Start here
The workspace owner creates API keys and webhooks in Developers. The API docs cover every endpoint, webhook events, signatures, test mode, safe retries and the JavaScript and Python libraries.
Try it safely
Create a test key (it starts cp_test_). It only sees and creates sample data, never counts toward your plan and never emails a family.
A webhook was switched off
After 20 failed deliveries in a row a webhook is switched off and you get an inbox notice. Fix the endpoint, turn it back on in Developers, and retry any failed delivery from the log.
