Instrument Product Analytics
Quick Start
- Inspect the application stack, installed Altertable packages, existing client initialization, and current tracking conventions.
- Read the canonical ingestion guide and the page for the operation being implemented:
- Use the project's installed SDK and types as the exact API reference. Reuse its existing Altertable client rather than creating another instance.
- Add the smallest instrumentation change at the source of truth for the action.
- Verify the success path, identity lifecycle, consent behavior, and the project's targeted checks.
Use the Product Analytics API reference only when an SDK is unavailable or a direct HTTP integration is intentional.
When to Use This Skill
- Adding or changing product event instrumentation in an application
- Initializing an Altertable SDK
- Identifying users after signup, login, or restored authentication
- Updating user or account traits
- Resetting client identity on logout
- Managing tracking consent, page views, or screen views
- Aliasing IDs during an identity migration or external-system integration
For questions about events already stored in Altertable, use query-product-events. For ordered conversion journeys, use analyze-funnels.
Implementation Workflow
1. Inspect Before Editing
Determine:
- whether the application is browser, React, mobile, server, or a mixed architecture
- which Altertable SDK and version are installed
- where the shared client is initialized
- how configuration and environment-specific API keys are supplied
- whether event names or properties already have project-owned types
- how authentication, logout, and consent are represented
Follow the repository's local conventions and the installed package types. Do not infer a signature from a skill example or from another SDK.
2. Define the Event Contract
Before adding a call, establish:
- the user action or business outcome the event represents
- the stable event name
- only the properties needed for filtering, grouping, or decisions
- the correct identity context
- whether the browser or backend is the source of truth
Prefer a small number of durable business events over low-level interaction noise. Track server-owned outcomes such as successful billing changes or completed background jobs from the backend.
3. Place Calls at Durable Boundaries
- Track an outcome after it succeeds, not when the user merely attempts it.
- Identify as soon as authenticated state is established or restored.
- Reset client identity on logout.
- Update traits when analytically relevant account state changes.
- Use aliasing only for explicit ID merges or migrations; normal signup and login flows use identification.
- Preserve existing consent gates and privacy behavior.
4. Verify
- Exercise the relevant success path and confirm the call occurs once.
- Check that failed or cancelled actions do not emit success events.
- Check anonymous-to-known identity behavior when authentication is involved.
- Check logout does not leave the prior user's identity active.
- If runtime access is available, confirm a non-production event reaches the intended Altertable environment without exposing user data.
Safety Rules
- Never send passwords, tokens, secrets, payment details, or regulated sensitive data as properties or traits.
- Do not hardcode environment-specific credentials in source files.
- Do not silently broaden tracking beyond the user's requested behavior.
- Do not initialize multiple competing clients.
- Do not replace established event names or property shapes without checking downstream dashboards, queries, and consumers.
- Do not bypass consent, privacy, or data-residency requirements to make an event appear.
Common Pitfalls
- Tracking before an operation succeeds, which inflates conversion metrics
- Adding duplicate initialization or duplicate listeners
- Using mutable data such as email as the stable user ID
- Forgetting to identify an already-authenticated user after a full reload
- Forgetting to reset identity on logout
- Using aliasing for routine authentication instead of an explicit ID merge
- Copying an API signature without checking the installed SDK version
- Sending properties that have no planned analytical use
