Six areas cover the whole journey: installing the SDK, modeling events, calling the API, shipping integrations, and locking down access. Pick a starting point, follow the path, skip what you know.
Getting started
Create a workspace, install the SDK and send your first event in under five minutes.

Docs answer most questions. For everything else, the engineers who built the API are one message away.

CAN’T FIND IT?
Ask the people who build the API. Send a request ID
or a failing payload and we’ll trace it on our side.

Full logs checked for every request ID
These are the guides teams open most in their first week, covering retries, live debugging, webhook signatures and going live. Short reads, real code, no theory you won’t use.

Hit a limit?
Requests over your rate limit return a 429 with a Retry After header, so your code knows exactly when to try again. No events are dropped, and upgrading never changes your API keys.
