Overview

1Sygnal Docs

1Sygnal ships in-app surveys, event tracking, and user identification across four SDKs. They’re not one API in four syntaxes — each platform’s operations, events, and API key setup differ where the underlying platform does, and every divergence is documented with its reason rather than smoothed over. Start with the Quickstart for a minimal end-to-end example on each platform, or jump straight to one:

Guides

  • Concepts — the platform-neutral domain model shared by all four SDKs: triggering, identity, throttling, survey lifecycle events, question types, offline persistence, and privacy/consent.
  • Platform Parity — a table of every operation and event, generated directly from the same contract fixtures the SDKs’ own test suites run against, so it can’t silently drift from reality.
  • SDK Versions and Distribution Model — current version numbers and how each SDK is (and isn’t yet) published.
