Where to start
If you have an API key already, Getting started gets you a
response in one curl. If you are still working out what the objects mean, read the
Glossary first — events, sessions and offers are easy to confuse.
Before you ship, read Versioning: the API is date-versioned, and pinning a version is what stops a future release changing a payload underneath you.
