Patterns and APIs beyond the basics, for when your app is past the proof-of-concept stage.

  • Webhooks: receive notifications when user data changes. Subscribe to activity_*, test_* and source_* events, verify HMAC signatures, handle retries.
  • App metadata: attach per-app JSON to activities, traces, tests, and users. A built-in key-value store, so you don't have to run your own database for small amounts of app state.
