No extensive coding is required. The Zapier App Connector uses standard REST endpoints that you can call with built-in actions and triggers. Use the authentication method described to securely connect. The documentation provides examples and test tools to verify data flow.
A full list of endpoints is provided in the endpoint list. Start with GET /contacts/:contactId to fetch a contact, then expand to tasks, notes, and other resources as needed. You can also POST, PUT, and DELETE to manage data.
Connections are secured with OAuth 2.0 or API keys, plus TLS encryption for transport. Rotate credentials periodically and use scoped permissions to limit access.
