Glossary explains API endpoint authentication trigger action and key fields used in the GHL Contacts API and Zapier App Connector
A URL path and HTTP method used to interact with a specific API function
Proof of identity that allows access to API resources via API keys or OAuth tokens

Authenticate using your GHL API key or OAuth token with the required scope. In Zapier connect the app and test the connection. Then set up a trigger to pull contact updates.
Be aware that endpoints have different methods and permissions. Use GET for reads and POST/PUT for changes as permitted by the scope. Always test in a sandbox.
No code is required for most automations via Zapier. Use triggers and actions to connect data between GHL and your apps.
Use Zapier test steps and sample data to verify the flow. Check endpoint responses and mapping.
With the contacts read only scope you can view data. If the API key includes write permissions you can create update or delete based on scope.
Updates may propagate in minutes depending on polling settings. Real time is possible with webhooks where supported.
Explore the endpoint list in the arm docs and try examples like get contact and list tasks to understand usage
