Use OAuth 2.0 to authorize the Zapier App Connector to access your Contacts data via the GHL Contacts API. Create a client in GHL, then configure the client ID and secret in Zapier to establish the connection.
In Zapier, connect the Contacts API using OAuth 2.0. Zapier handles token refresh automatically and prompts you to grant access.

This glossary covers authentication, endpoints, data mapping, and workflows to help you design robust automations.
The process of granting Zapier App Connector access to GHL data using OAuth 2.0; tokens are exchanged to secure API calls.
URLs you call with HTTP methods to read and modify data, such as GET, POST, PUT, and DELETE.
Real-time notifications sent to Zapier when events occur in GHL.
Data fields defined for contacts, tasks, notes, and appointments used in mapping.
Trigger nurture emails or SMS when a contact’s tasks are completed.
Create tasks automatically from notes or appointments to keep teams aligned.
Aggregate notes into a daily summary and push to Slack or email.
In Zapier, add a new connection and choose Contacts API as the trigger/app.
Complete OAuth 2.0 flow between GHL and Zapier; verify scopes.
Map contactId, IDs, and data fields; run test to ensure data flows.
To connect, you will use OAuth 2.0 to authorize Zapier App Connector to access your GHL Contacts data. This involves creating an OAuth client in your GHL account and supplying the client ID and secret to Zapier to establish the connection. Once authorized, Zapier can securely call the GHL endpoints on your behalf, and tokens are refreshed automatically to maintain uninterrupted automation.
The Contacts API exposes a variety of endpoints for reading and writing data, including endpoints for contacts, tasks, notes, and appointments. You can retrieve, create, update, and delete records as needed; some endpoints also support bulk and business-scoped access.
Field mapping lets you align GHL data with your Zapier fields. Start by selecting the source fields (e.g., contactId, taskId, note content) and map them to your Zapier action fields. Test the mapping to confirm data appears correctly in your workflow.
GHL imposes typical API rate limits based on your plan. When limits are reached, requests may be throttled. Design your Zaps to handle retries gracefully and implement exponential backoff where possible.
Yes. You can trigger actions from changes to contacts, tasks, notes, and appointments. Configure triggers on the relevant endpoints so your workflows respond as soon as data changes occur.
Some endpoints support pagination via standard paging parameters. If a response is paginated, your Zapier integration can be configured to fetch subsequent pages automatically until all data is retrieved.
Zapier provides logs and task history for each connection. You can review run details, errors, and data mappings to diagnose issues and optimize your automations.
Due to high volume, we will be upgrading our server soon!
