Authenticate requests to the Contacts API using your API credentials and proper scopes. For read-only data, use the provided Scope: contacts.readonly to limit access.
Grant access to your GHL data by authenticating the Zapier App Connector within your GHL account. Use OAuth 2.0 or API keys as configured in your setup, and ensure the secret is secured.
Available endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/tasks/:taskId, GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id, GET /contacts/:contactId/appointments, GET /contacts/, GET /contacts/business/:businessId, and for write operations: POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags. Note: API Endpoint9 refers to the contacts.write permission; actual endpoints above cover write operations.

Automate data flows without writing code; trigger-based automation across apps.
Centralize data mapping to reduce manual entry and errors.
Scale workflows quickly with templates and reusable steps.
Key elements include endpoints, triggers, actions, method paths, and key fields that power your GHL to Zapier automation.
A specific URL and HTTP method that performs a defined action in the GHL API.
An event in GHL that starts an automation in Zapier when conditions are met.
The process of verifying identity to access the GHL API, typically via OAuth 2.0 or API keys.
Critical data fields used to uniquely identify and map records (e.g., contactId, email).
Automatically enrich contact records from your CRM to marketing tools and contact lists.
Route new leads to the right teams via tasks, notes, and tags in Zapier.
Send alerts to Slack, email, or Teams when tasks update or approach due dates.
Generate an API key or OAuth client in GHL to authorize the connection.
In Zapier, set up the Contacts API app, connect using your credentials, and select endpoints and scopes.
Run tests, validate mappings, and then enable the Zapier integration in your workflow.
Endpoints in the GHL Contacts API allow reading and writing core contact data, tasks, notes, and related items. Common read endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, and GET /contacts/:contactId/notes. For creating or updating data, use POST /contacts/, POST /contacts/:contactId/tasks, and PUT or DELETE variants as needed. In Zapier, these endpoints enable automated syncs between your CRM and your apps, reducing manual data entry. These endpoints empower no-code automations by exposing the essential actions you need to keep systems aligned and up-to-date.
Authentication relies on OAuth 2.0 or API keys. Start by creating credentials in GHL for the Zapier App Connector, then configure those credentials in Zapier to authorize API calls. Use the minimum required scopes (for example, contacts.readonly for read-only workflows) and elevate permissions only as your automation requires. Regularly rotate credentials and secure your keys to maintain a safe integration.
You can read and write a broad set of data: contacts, tasks, notes, and appointments. Read operations pull details like contactId, name, email, and associated tasks or notes; write operations allow creating and updating contacts, tasks, notes, and tags. The exact capabilities depend on the credentials and scopes you configure in GHL and the Zapier app.
Yes. You can create and update tasks and notes for a contact, and you can create or assign tags. Use POST and PUT endpoints to modify data, and ensure your Zapier mappings correctly reflect the fields you want to update on each record.
Field mapping in Zapier lets you align GHL fields (such as name, email, phone) with your target app. Use test records to verify mappings, and adjust data types and formats to prevent mismatches during transfers.
Webhooks are supported for real-time updates. Configure GHL webhooks to send events to your Zapier webhook URL, then trigger Zaps on events like contact or task updates. This enables near-instant automation in response to changes.
Rate limits depend on your API plan. Plan calls accordingly, implement exponential backoff retries in Zapier, and batch requests where possible to avoid hitting limits. Monitoring dashboards can help you tune frequency and concurrency.
Due to high volume, we will be upgrading our server soon!
