Patterns and APIs beyond the basics. Reach for these once your app is past the proof-of-concept stage.

  • Webhooks: receive real-time notifications when user data changes. Subscribe to activity_* and test_* 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 stand up your own database for small amounts of app state.
