Versioning

The version is in the path. Within v1 changes are additive only: new fields, enumeration values, optional filters and endpoints. Anything else ships as v2. Ignore unknown fields and treat unknown enumeration values as opaque.

Playground

Every endpoint page has a playground. Paste an API key in the authorization field to run requests against your own workspace. Keys stay in your browser.
