To access the Contacts API, obtain a valid OAuth token or API key from your GHL account and include it in your requests. Always use secure storage for credentials and follow rate limits.
Create or connect a Zapier app connection using OAuth or API credentials. Store tokens securely and refresh as needed. The connector will pass authentication details to each API call.

Automate everyday contact workflows without writing code.
Safely sync data between GHL and your apps with no custom development.
Trigger-based automations reduce manual data entry and errors.
This glossary explains common terms used when integrating the GHL Contacts API with the Zapier App Connector.
A specific URL path you can call in the API to perform an operation.
Process to verify identity and authorize API requests.
Event that starts an automation in Zapier.
Operation performed by Zapier in response to a trigger.
Automatically mirror new and updated contacts from GHL into your app via Zapier.
Create tasks in your project or CRM when a task is added or updated in GHL.
Use notes attached to a contact to trigger updates to your app, reminders, or reports.
Connect your GHL account and your Zapier app, then securely save credentials.
Choose relevant contact events (create/update, notes, tasks) and map to actions in your app.
Run full tests, validate data paths, and enable the Zap to run automatically.
The easiest way is to set up a Zap that uses the Contacts API as the trigger source (e.g., New Contact) and your app as the action. This lets you start automations without writing code. If you need more complex logic, you can chain multiple steps or use filters in Zapier to refine when the automation runs.
You typically authenticate via OAuth for the Zapier App Connector and API tokens for the GHL Contacts API. OAuth is user-friendly and secure for end users, while API tokens are suitable for service accounts. Always follow best practices for storing credentials and rotating them regularly.
Use OAuth tokens with short lifespans and refresh tokens where supported. Store tokens securely in a vault and avoid embedding them in prompts or client-side code. Enforce least-privilege access by scoping tokens to only the needed endpoints.
Rate limits depend on your GHL plan and API usage. Plan for bursts by spreading requests and using exponential backoff on retries. If you exceed limits, implement retry logic and consider batching where appropriate.
Visit the Zapier and GHL developer docs for detailed guides, sample zaps, and endpoint references. If you need tailored guidance, reach out to support with your use case and data flow diagram.
