Resolve a SaaS Tier 1 Support Case

Investigate API errors and communicate a Tier 1 SaaS support resolution.

Introduction

30 Second Summary

When customer reviews disappear from a product page, shoppers lose useful context while the brand needs answers quickly. The first clue can look reassuring while hiding the real problem.

In this project, you will investigate a fictional brand's missing Ratings and Reviews content in Google Chrome and Microsoft Edge. You will uncover an API error hidden behind HTTP 200. Your evidence becomes a complete Tier 1 support-case portfolio.

What You'll Build

Your finished portfolio shows one support case moving from comparable browser evidence to a corrected JSON diagnosis and a client-ready response.

By the end of this project, you'll have:

A browser evidence comparison that records reproducible request details from Chrome and Edge.
A searchable 24-term acronym card covering B2B support, web troubleshooting, Bazaarvoice, and ecommerce terminology.
A complete communication pack with a client email, an internal case note, and a 60-second interview story.
Secret Mission: Triage an account-level feature limitation and prepare an evidence-led escalation without promising activation.

Are there any prerequisites?

No support experience is required. A Windows computer with Chrome, Edge, and Visual Studio Code is enough because the case includes self-contained evidence.

Before We Start

This is your moment to define the Tier 1 support role you are pursuing and connect this realistic client case to the troubleshooting and communication skills that role requires.

Set Up Your Support Workspace

A live support case creates several kinds of evidence. A repeatable workspace keeps each artifact tied to the same investigation.

In this step, you will confirm that Google Chrome, Microsoft Edge, and Visual Studio Code launch. You will create a dedicated workspace before locating the browser panels used for evidence.

In this step, get ready to:

Confirm that Google Chrome, Microsoft Edge, and Visual Studio Code launch.
Create the support workspace with three empty case files.
Locate Console and Network in both browsers.

Confirm your tools launch

This simulation uses tools that are already installed on your Windows computer. A quick launch check confirms that each one is available before the investigation begins.

Enter Google Chrome in the search box on the Windows taskbar.
Select Google Chrome from the search results.
Enter Microsoft Edge in the search box on the Windows taskbar.
Select Microsoft Edge from the search results.
Enter Visual Studio Code in the search box on the Windows taskbar.
Select Visual Studio Code from the search results.

That's your tool check complete: all three apps are open without extensions, accounts, or credentials.

One of the apps won't open?

Search again using the full product name shown above. Check the Windows taskbar for an existing app window if selecting the result seems to do nothing.

If an app still does not open, help me troubleshoot an installed Windows app that will not launch.

Create the case workspace

A Visual Studio Code workspace is an opened folder that keeps related files together. Your workspace separates investigation notes from client-facing communication.

Switch back to Visual Studio Code.
Select File from the top menu.
Select Open Folder....
Select Desktop in the folder dialog.
Select New Folder.
Enter bazaarvoice-tier1-lab as the folder name.
Select Select Folder.
Choose Yes if Workspace Trust appears.

You should see bazaarvoice-tier1-lab at the top of the Explorer view. Visual Studio Code now treats this folder as your workspace.

Each empty Markdown file has a distinct audience. Creating the files now gives every later observation a clear destination.

Select New File... in the Explorer view.
Enter case-workbook.md.
Press Enter.

You should see the empty case-workbook.md file in the Explorer.

Select New File... in the Explorer.
Enter client-email.md.
Press Enter.
Select New File... in the Explorer.
Enter acronym-glossary.md.
Press Enter.

Your workspace now shows all three empty files. Each file is ready for a different part of the case.

Why split the case into three files?

The case-workbook.md file holds browser evidence, case triage, diagnosis, internal notes, and your interview story.
The client-email.md file holds client-facing communication.
The acronym-glossary.md file holds the support and ecommerce reference card.

Locate browser evidence tools

Browser DevTools exposes the objective evidence behind a client report. The Console shows page messages.

The Network panel records browser requests. The Bazaarvoice Conversations API troubleshooting page gives both browsers the same public source for this simulation.

Switch to Google Chrome.
Select Chrome's address bar.
Enter https://developers.bazaarvoice.com/v1.0-ConversationsAPI/docs/troubleshooting.
Press Enter.

When internet access is available, Chrome displays the Bazaarvoice Conversations API troubleshooting page.

Switch to Microsoft Edge.
Select Edge's address bar.
Enter https://developers.bazaarvoice.com/v1.0-ConversationsAPI/docs/troubleshooting.
Press Enter.

When internet access is available, Edge displays the same troubleshooting page. This shared page keeps the browser comparison consistent.

Use the supplied evidence excerpts for the simulation if either browser cannot reach the page.

Switch back to Google Chrome.
Press Ctrl+Shift+J.

Chrome opens DevTools with the Console available.

Select the Network tab in Chrome DevTools.

Chrome's Network panel is now ready for evidence capture.

Switch back to Microsoft Edge.
Press Ctrl+Shift+J.

Edge opens DevTools with the Console available.

Select the Network tab in Edge DevTools.

Edge's Network panel is now ready for the same evidence workflow.

Can't find a DevTools panel?

Widen DevTools if a panel name is hidden. Use the hidden-tab menu if the Network tab still does not fit.

If the shortcut does not respond, select the browser page before trying it again. You can also ask for help locating Console and Network in Chrome or Edge.

Before the final check, do you expect both browsers to expose the same two evidence panels?

Press Ctrl+Shift+J in Google Chrome.
Press Ctrl+Shift+J in Microsoft Edge.
Return to Visual Studio Code.

In both browsers, you should see DevTools with the Console available after using the shortcut. You should also be able to select the Network panel.

In Visual Studio Code, the Explorer should show bazaarvoice-tier1-lab with case-workbook.md, client-email.md, and acronym-glossary.md inside it.

Your support workspace is ready. Next, you will capture comparable request evidence in Chrome and Edge.

Capture Browser Evidence

Your support workspace is ready. The next goal is to turn a client symptom into evidence that another analyst can review.

Google Chrome and Microsoft Edge expose browser requests through DevTools. You will store matching observations in the workspace already open in Visual Studio Code.

A client report gives you the symptom. Request evidence gives you an objective trail to investigate before you propose a fix.

In this step, get ready to:

Capture a main document request from the Bazaarvoice troubleshooting page in Chrome.
Compare the same request evidence in Edge.
Build a 24-term support acronym reference.

Capture the Chrome request

The main document request represents the page load itself. Its request row gives you a consistent place to capture the page address plus the request type and result.

Use live Network data when the troubleshooting page loads. The supplied evidence keeps the simulation available when your internet connection blocks the live page.

✔️ The page loads

Switch back to Chrome from earlier.
Select the Network tab in DevTools.
Reload the troubleshooting page.
Select the main document request row after the reload finishes.
Read the Status and Type values from the request row.
Inspect the Headers panel for the request URL.
Choose one useful header observation from the Headers panel.
Inspect the Response panel for one response observation.

What makes this evidence reproducible?

A reproducible record identifies the request before describing what happened. The request URL anchors every other observation to the same page load.

Select case-workbook.md in the Visual Studio Code Explorer sidebar.
Add a Chrome evidence record containing the URL, Status, Type, one header observation, and one response observation.
Save case-workbook.md.

You should see a Chrome evidence record with all five required fields in your workbook.

ⓧ The page will not load

Keep the Network tab visible in Chrome.
Reload the troubleshooting page once.
Return to the supplied Chrome evidence excerpt from the simulation.
Select case-workbook.md in the Visual Studio Code Explorer sidebar.
Add a Chrome evidence record by transcribing the supplied URL, Status, Type, header observation, and response observation exactly.
Add Evidence source: supplied excerpt beneath the record.
Save case-workbook.md.

You should see a complete Chrome record with its simulation source clearly identified.

Why capture all five fields?

The URL identifies the resource. Status and Type summarize the request at a glance.

Headers provide request context. The response observation records what the server returned for closer investigation.

Your first browser record now has a clear source and a repeatable evidence structure.

No request rows in Chrome?

Keep the Network tab selected before reloading the page.
Check whether an active filter is hiding the main document request.
Use the supplied evidence excerpt if the page still cannot load.

help me find the main document request in Chrome DevTools

Compare the Edge request

Comparable evidence uses the same fields in each browser. This keeps interface layout differences separate from request behavior.

Switch back to Edge from earlier.
Select the Network tab in DevTools.
Reload the troubleshooting page.

The reload determines whether you continue with the live request or the supplied Edge evidence.

✔️ Request rows appear

Select the main document request row.
Read the Status and Type values from the request row.
Inspect the Headers panel for the URL and one useful header observation.
Inspect the Response panel for one response observation.
Add an Edge evidence record to case-workbook.md using the same five fields as the Chrome record.
Save case-workbook.md.

You should see matching evidence structures for Chrome and Edge.

ⓧ Request rows do not appear

Return to the supplied Edge evidence excerpt from the simulation.
Add an Edge evidence record to case-workbook.md.
Transcribe the supplied URL, Status, Type, header observation, and response observation exactly.
Add Evidence source: supplied excerpt beneath the record.
Save case-workbook.md.

You should see a complete Edge record with its simulation source identified.

Add a Browser comparison section beneath the two evidence records.
Create a two-column comparison labeled Shared evidence and Interface differences.
List URL, Status, Type, Headers, and Response under Shared evidence.
Record the cosmetic layout differences you observed under Interface differences.
Save case-workbook.md.

You should see two browser records with identical evidence fields. Your comparison should keep presentation differences separate from the request observations.

Cosmetic Differences Stay Cosmetic

Chrome and Edge may place fields differently. They may also show different supporting columns in the request table.

A technical fault requires a meaningful difference in the request or response evidence. Interface placement alone does not demonstrate a fault.

Build the acronym reference

Support acronyms become useful when you can explain them in plain English. This reference card connects each term to the work a Tier 1 analyst performs.

Business and support terms describe customer relationships plus the processes used to deliver reliable service.

B2B: business-to-business. It covers applications or transactions between businesses.
B2C: business-to-consumer. It covers applications or transactions between a business and consumers.
CRM: customer relationship management. It uses connected technologies to track customer relationships and interactions.
SLA: service level agreement. It records service responsibilities plus expected performance and resolution commitments.
KPI: Key Performance Indicator. It measures progress toward an intended result.
ROI: return on investment. It compares the benefit of an investment with its cost.
QA: quality assurance. It builds confidence that defined quality requirements are being met.
SOP: Standard Operating Procedure. It provides a repeatable set of steps for a routine task.

Web troubleshooting terms describe how browsers locate resources plus how systems exchange data.

API: Application Programming Interface. It provides features and rules that let software systems interact.
HTTP: HyperText Transfer Protocol. It transfers web resources between clients and servers.
HTTPS: HyperText Transfer Protocol Secure. It uses TLS to encrypt communication between a client and server.
URL: Uniform Resource Locator. It specifies where an internet resource can be found.
JSON: JavaScript Object Notation. It is a data-interchange format used to structure information.
CORS: Cross-Origin Resource Sharing. It uses HTTP headers to control browser access to responses from another origin.
CDN: Content Delivery Network. It uses geographically distributed servers to deliver stored copies of data.
TLS: Transport Layer Security. It protects network communication from tampering and eavesdropping.

Bazaarvoice and ecommerce terms describe review content plus the identifiers used around products and shoppers.

UGC: User-Generated Content. It is content created by a brand's users.
R&R: Ratings and Reviews. It is product feedback that combines rating scores with written reviews.
PDP: product display page. In this case, it is the product page where Ratings and Reviews content appears.
GTIN: Global Trade Item Number. It is a globally unique number used to identify a product or service.
UPC: Universal Product Code. It is the scannable barcode element associated with a product identifier.
EAN: European Article Number. It is a 13-digit GTIN used by retailers in many regions.
SKU: Stock Keeping Unit. It is an internal code a company uses to track inventory.
PII: Personally Identifiable Information. It is information that can distinguish or trace an individual's identity.

Connect Terms to Support Work

Use SLA to explain how service commitments guide prioritization and client updates.
Use API to explain where request and response evidence appears during an integration problem.
Use HTTP to explain how the request status provides an initial troubleshooting signal.
Use JSON to explain where structured response details can appear.
Use R&R to connect the technical symptom with the missing product content.
Use PII to explain why support evidence must protect shopper information.

Select acronym-glossary.md in the Visual Studio Code Explorer sidebar.
Create headings for Business and support, Web troubleshooting, and Bazaarvoice and ecommerce.
Add the eight matching entries beneath each heading using the reference above.

You should now see three groups of eight terms. Every entry should include an expansion and a plain-English meaning.

Add a Why Tier 1 cares note to the SLA, API, HTTP, JSON, R&R, and PII entries using the support focus above.
Save acronym-glossary.md.

Before your final review, do you expect another analyst to find the same five fields in both browser records?

Review the Chrome record in case-workbook.md for URL, Status, Type, Headers, and Response evidence.
Review the Edge record in case-workbook.md for the same five evidence fields.
Confirm the browser comparison contains shared evidence and cosmetic interface differences.
Count the 24 entries in acronym-glossary.md.
Confirm at least six glossary entries include a Why Tier 1 cares note.

You should see two directly comparable browser records plus three glossary groups containing eight terms each. Six or more terms should also explain their Tier 1 relevance.

Your browser evidence and terminology reference are ready. Next, you will use them to triage the fictional Ratings and Reviews report.

Diagnose the Hidden API Error

You already captured comparable request evidence in Google Chrome and Microsoft Edge. Now you will use that evidence to investigate why Ratings and Reviews content is missing from a production PDP.

An HTTP 200 status can encourage a quick success conclusion. This case tests that conclusion against the API response body before you choose a next action.

In this step, get ready to:

Capture the reported impact plus the environment plus the scope plus the reproduction information.
Inspect the response body to identify the hidden error.
Correct the initial hypothesis to make a resolve-or-escalate decision.

Triage the client report

Ticket triage separates reported facts from working assumptions. That separation lets you revise a hypothesis while preserving the original evidence.

Return to case-workbook.md from earlier.
Add a case section beneath your browser comparison for the fictional production outage.
Record the impact as missing Ratings and Reviews content on the production PDP.
Record the environment as production.
Record the scope as Ratings and Reviews content on the reported production PDP.
Treat wider page or client impact as unconfirmed.
Record reproduction information showing that the content is absent while the browser request returns HTTP 200.

Pause before reading the supplied body to decide whether HTTP 200 alone proves that the content request succeeded.
Record the initial hypothesis that HTTP 200 means the API request succeeded.

Inspect the response body

A JSON response body can describe the application outcome in more detail than the HTTP status. Reading both layers prevents a successful-looking status from ending the investigation too early.

Inspect the supplied response body by reading this evidence:

"Errors": [
  {
    "Message": "The passkey provided is invalid.",
    "Code": "ERROR_PARAM_INVALID_API_KEY"
  }
]

What Does This Evidence Prove?

The Errors field shows that the response body contains an application error.
The message states that the supplied passkey was invalid.
The code identifies the error as ERROR_PARAM_INVALID_API_KEY.

The initial hypothesis now falls short. The response body proves that the API rejected the passkey despite the HTTP 200 status.

Return to case-workbook.md.
Record the response message as The passkey provided is invalid..
Record the response code as ERROR_PARAM_INVALID_API_KEY.
Record the confirmed diagnosis that the API rejected the passkey despite returning HTTP 200.
Use the official Bazaarvoice troubleshooting guidance from earlier to confirm which checks belong to this error code.

What Does the Official Guidance Add?

The documented possibilities include a staging-versus-production mismatch. They also include a typo or an unapproved key.

These possibilities require account evidence before one can become the root cause. Your diagnosis stays accurate by keeping each one unconfirmed.

Correct the diagnosis and choose the next action

A sound resolve-versus-escalate judgment separates the confirmed failure from its possible causes. Tier 1 can move the investigation forward without guessing about configuration that it cannot verify.

Correct the initial hypothesis to state that HTTP 200 did not prove the content request succeeded.
Add staging-versus-production mismatch as an unconfirmed possibility.
Add a passkey typo as an unconfirmed possibility.
Add an unapproved key as an unconfirmed possibility.
Label all three possibilities as unconfirmed.

Why Keep the Possibilities Unconfirmed?

Only account evidence can distinguish an environment mismatch from a typo or an approval issue. Labeling each possibility as unconfirmed protects client trust.

Record the safe next action as verifying the passkey plus the environment in authorized client configuration.
Record escalation as required when Tier 1 lacks authorized configuration access.
Record escalation as required when the verified configuration is correct but the error persists.
Save case-workbook.md.

Pause before your final review to predict which entries should be confirmed facts.
Confirm that the triage record includes every requested field.
Confirm that the initial HTTP 200 hypothesis is corrected.
Confirm that the exact message The passkey provided is invalid. appears.
Confirm that the exact code ERROR_PARAM_INVALID_API_KEY appears.
Confirm that the documented possibilities remain unconfirmed.
Confirm that the authorized configuration check appears as the safe next action.
Confirm that both escalation conditions appear.

You will see a complete trail from client impact to response evidence. You will also see a clear boundary for escalation.

Strong work. Your diagnosis now follows the evidence without overstating a root cause. Next, you will turn this investigation into a client response with clear ownership.

Own the Client Communication

Your diagnosis already proves that the response body can overturn a successful-looking HTTP status. The next goal is to turn that evidence into communication the client can act on.

A technically correct diagnosis still creates a poor support experience when the client cannot see the impact, the evidence, the next action, or the owner. You will package those pieces into a client email.

You will preserve the investigation in an internal note. You will also build an interview story that demonstrates your support judgment.

In this step, get ready to:

Write a client email that explains the verified evidence in plain English.
Create an internal case note that supports a clean analyst handoff.
Build a 60-second interview story from your investigation.

Write a client-ready email

A client-facing B2B support email separates verified evidence from possible causes. This protects trust while giving the client a useful next action.

Return to client-email.md from the Explorer sidebar in your Visual Studio Code workspace.
Add a useful subject line that names the missing production Ratings and Reviews content.
Start the body by acknowledging the impact of the missing production reviews.
State that the content request returned HTTP 200.
Add the verified error code ERROR_PARAM_INVALID_API_KEY.
Quote The passkey provided is invalid. as supporting response evidence.
Explain that the API rejected the passkey despite the successful-looking status.
Request verification of the passkey within the authorized production configuration.

What keeps the email client-safe?

Verified evidence belongs in definitive language. Possible causes stay labeled as possibilities until authorized configuration evidence confirms one.

Ownership names the next check. It also explains exactly when escalation becomes necessary.

Close with a commitment to update the client after the authorized configuration check.
State that you will escalate if Tier 1 lacks configuration access.
State that you will escalate if the verified configuration still produces the error.
Save client-email.md.
Scan the email for credentials or personal data.
Remove any unsupported promise about resolution timing.

In client-email.md, you should now see a complete path from acknowledgment to ownership. You have translated the technical finding into a response the client can follow.

Create a reusable internal case note

An internal case note lets another analyst continue the investigation without repeating your work. It records what is confirmed alongside the conditions that require escalation.

Separating confirmed facts from possible causes can feel fiddly. Clear section labels prevent assumptions from turning into false conclusions.

Return to case-workbook.md from earlier.
Add an Internal Case Note heading below your diagnosis.
Add a Scope section that names the missing production PDP Ratings and Reviews content.
Add a Reproduction section that summarizes the Chrome and Edge checks.
Add an Evidence section that records HTTP 200 alongside ERROR_PARAM_INVALID_API_KEY.
Add a Confirmed Diagnosis section that states the API rejected the passkey.
Add an Unconfirmed Possibilities section that lists an environment mismatch, a typo, or an unapproved key.
Add an Actions Taken section that summarizes the browser reproduction, response inspection, and documentation review.

Keep the handoff testable

A reusable note gives the next analyst enough detail to reproduce the issue. It also shows which evidence supports the current diagnosis.

Clear escalation conditions turn the handoff into a decision. The next analyst can continue from your last verified point.

Add an Information Still Needed section that requests authorized confirmation of the production environment and passkey status.
Add an Escalation Conditions section that covers missing Tier 1 access and a persistent error after configuration verification.
Replace every real passkey or item of Personally Identifiable Information with descriptive placeholder text.
Save case-workbook.md.

Your internal note should now separate scope, reproduction, evidence, confirmed findings, open possibilities, next actions, and escalation conditions. Another analyst can continue the case without rebuilding your investigation.

Turn the case into a STAR story

The STAR method organizes an interview answer into Situation, Task, Action, and Result. Your strongest evidence is the moment you challenged the initial status-code assumption.

Add a 60-Second STAR Interview Story heading to case-workbook.md.
Write the Situation as a production PDP with missing Ratings and Reviews content.
Write the Task as investigating the symptom while protecting client trust.
Write the Action as reproducing the issue across both browsers.
Add response-body inspection to the Action section.
Add your corrected assumption to the Action section.
Write the Result as an evidence-backed configuration check with clear escalation conditions.
Save case-workbook.md.

Before reading the story aloud, consider whether the Action section clearly shows how your investigation changed direction.

Read your STAR story aloud at a steady interview pace.
Trim repeated details if the story runs longer than about 60 seconds.
Read the revised story aloud once more.

You should hear all four STAR parts within a concise answer. The result should show ownership without claiming that the incident was fully resolved.

Before the final email read-through, consider whether every sentence supports one of the five client needs below.

Return to client-email.md.
Read the complete email aloud.

Confirm the opening acknowledges the missing production reviews.
Confirm the verified evidence includes HTTP 200 and ERROR_PARAM_INVALID_API_KEY.
Confirm the plain-English explanation says the API rejected the passkey.
Confirm the next action is an authorized configuration check.
Confirm the closing owns the update or escalation.

You should be able to point to one sentence or short section for every check. That gives the client a complete path from impact to next action.

Check that the subject line identifies the production review issue.
Check that the email contains no credentials or personal data.
Check that the email makes no unsupported resolution promise.
Save client-email.md after any final edits.
Read the final version aloud once more.

All five communication parts should now sound clear without exposing sensitive information. You now have a client-ready response, a reusable analyst handoff, and an interview story grounded in evidence.

Secret mission

Triage an Escalation-Only Case

A second client is blocked by a feature limitation that Tier 1 cannot verify at account level. Can you explain the evidence without guessing, then prepare a focused escalation that gives the next team a clear question to answer?

Clean Up Your Resources

Your completed case work lives in local files with no ongoing charges. Choose whether to keep the workspace ready, close the open tools for now, or remove the lab entirely.

Resources you used:

The bazaarvoice-tier1-lab local workspace folder containing case-workbook.md, client-email.md, and acronym-glossary.md.

Keep everything running

Leave everything in place if you plan to revisit the investigations or practise explaining your decisions.

Keep the bazaarvoice-tier1-lab folder on your computer.
Return to the workspace in Visual Studio Code when you want to review your evidence or rehearse your interview story.

Pause - I'll come back to this later

Pausing means closing the open tools while leaving every local file in place.

Close Google Chrome.
Close Microsoft Edge.
Close Visual Studio Code.
Return later by opening the bazaarvoice-tier1-lab folder in Visual Studio Code.

Your Markdown files remain in the workspace for your next practice session.

Delete - I don't want to use this again

Deleting the lab becomes permanent after its folder leaves your computer's deleted-items area. The steps target only bazaarvoice-tier1-lab.

Close Visual Studio Code.
Use Windows search to locate bazaarvoice-tier1-lab.
Open the folder's containing location from the search result.
Delete the bazaarvoice-tier1-lab folder.
Permanently remove only bazaarvoice-tier1-lab from your computer's deleted-items area.
Search for bazaarvoice-tier1-lab again.

You should see no matching workspace folder. This confirms that all three lab files have been removed.

Nice Work!

Excellent work! You've completed a realistic Tier 1 support case portfolio. Your workbook now demonstrates evidence-led troubleshooting from the client report through justified escalation.

What you learned:

Capture comparable browser evidence across Google Chrome and Microsoft Edge. Organize 24 support, web, Bazaarvoice, and ecommerce acronyms into a searchable reference card.
Build an evidence-based diagnosis for an API failure hidden behind HTTP 200 by inspecting its JSON response body. Separate verified facts from possible causes before choosing whether to resolve or escalate.
Translate one investigation into clear client communication. Your finished outputs include a customer-first email, a handoff-ready internal note, and a 60-second STAR interview story.
Secret Mission: Use ERROR_UNSUPPORTED to triage an account-level feature limitation. Prepare an evidence-led escalation without promising activation or a resolution timeline.
