Authenticate securely with OAuth or API keys to grant your App access to contact data. Use the GHL API credentials provided in your developer dashboard and follow scope-specific permissions to control read or write access.
Your App (Zapier Connector) authenticates to GHL using the same OAuth flow or API token approach. Store tokens securely and renew them before expiry to maintain uninterrupted access.

You can read a wide range of contact data using endpoints like GET /contacts/:contactId and GET /contacts/:contactId/tasks. This enables you to surface contact details, tasks, notes, and history in your App. Use appropriate scopes to limit access to only the data you need. Consider caching responses in your app to reduce repeated API calls and improve performance.
Authentication is typically handled via OAuth 2.0 or API keys. Register your app in the GHL developer portal to obtain client credentials or tokens, and store them securely. Your app should refresh tokens automatically to maintain access. Follow best practices for secure storage and rotation of credentials.
GHL enforces rate limits per endpoint and per API token. Plan your requests, batch calls where possible, and implement exponential backoff on 429 responses. Monitor usage via the dashboard to avoid interruptions.
Yes. The API supports creating and updating contacts, tasks, and notes. Use POST for creation, PUT for updates, and DELETE when needed. Ensure your app respects write scopes and handles optimistic locking where supported.
Map fields by aligning your app data model with GHL fields (e.g., contactId, email, name). Use IDs for linking and ensure consistent data types. A field mapping matrix helps maintain data integrity.
If a token expires, trigger a refresh flow automatically. Re-authenticate and renew your access tokens before making requests. Implement error handling to retry failed calls after a refresh.
Logs are available in your app’s dashboard and the GHL developer portal. Look for request/timestamp, endpoint, status, and error messages to diagnose issues. Use webhooks and retries to ensure reliability.
