Full API reference
Where the exact shapes live, and why they are not restated here.
The authoritative reference is the API Reference page inside the app. It is generated against your workspace, so it shows the real request and response shapes — including any custom objects and fields you have added, which no static document could know about.
Why this page does not restate it
A second copy of an API contract is a second thing to keep correct, and the copy is always the one that goes stale. Anything written here about exact field names would eventually contradict the app, and a reader has no way to tell which is right.
What is public
- CRM — accounts, contacts, leads (including convert), opportunities, activities
- Studio apps — list and execute registered actions
Objectives, chat, campaigns and the Hub are not public API surfaces. To start work externally, use a routine webhook; to file something in, use the inbound webhook.
