Access to the Contacts API via the Zapier App Connector requires proper authentication. Use the OAuth flow or API keys issued for the GHL Contacts API with the scope: contacts.readonly.
In Zapier, authorize the Contacts API connection and grant the necessary scopes. This ensures secure, token-based access between GHL and your automations.
Endpoints covered 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, 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. The API also defines a write scope (contacts.write) where applicable.
Trigger: when you need full context on a single contact, pull the contactId and retrieve the contact details plus related tasks.
Actions: GET /contacts/:contactId to fetch the contact; GET /contacts/:contactId/tasks to list tasks; optionally GET a specific task with /contacts/:contactId/tasks/:taskId.
GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId (for a specific task)
Trigger: keep your CRM roster in sync by pulling the full list of contacts.
Actions: GET /contacts/ to fetch all contacts; optionally filter by businessId or other criteria.
GET /contacts/
Key fields: contactId
Trigger: when a contact field updates in your system, push the change to GHL.
Actions: PUT /contacts/:contactId to update fields on the contact.
PUT /contacts/:contactId
Key fields: contactId
Automate routine CRM tasks without writing a line of code.
Leverage native triggers and actions to build powerful workflows quickly.
Scale data access in real time with minimal setup and maintenance.
This glossary covers essential terms and processes used when connecting the GHL Contacts API with the Zapier App Connector, including identifiers, endpoints, and CRUD operations.
A unique identifier assigned to a contact in GHL; used to fetch, update, or relate data.
A unique identifier for a task associated with a contact; used to retrieve or modify a specific task.
A notes record attached to a contact; stores text notes and metadata.
A scheduled event linked to a contact, such as a meeting or call.
Automatically create a contact in Contacts API when a new lead enters Zapier, then pull related tasks and notes for immediate action.
Sync notes from emails, forms, or calls to the contact’s notes endpoint to maintain a complete activity history.
Create and complete tasks automatically based on events to ensure follow-ups never slip through the cracks.
In Zapier, authorize the Contacts API connection and grant the required scope (contacts.readonly).
Map fields and select endpoints to automate workflows between GHL and your apps.
Run end-to-end tests and deploy your automation to production.
Authentication for the Contacts API can be performed via OAuth tokens or API keys issued by GHL for the Contacts API. When connected through the Zapier App Connector, ensure the token has the required scope, especially contacts.readonly. This keeps your data access secure and compliant. If you encounter token expiration, refresh through the OAuth flow or re-authenticate the connection in Zapier to restore access quickly.
No traditional coding is required to set up these integrations. Zapier provides triggers and actions that map to the Contacts API endpoints. You can configure workflows with point-and-click builders, while advanced users may add simple logic in Zapier to handle conditional flows. For complex transformations, use built-in formatter steps or data utilities within Zapier.
Rate limits depend on your GHL plan and the API endpoint. Typical guidance is to design efficient workflows that batch requests where appropriate and cache results when possible. If you hit limits, implement exponential backoff and retry logic in your Zapier automations. Contact support if you consistently exceed quotas to adjust allowances or optimize calls.
Creating and updating contacts is supported via endpoints like POST /contacts/ and PUT /contacts/:contactId. Note that writing operations require the contacts.write scope. For updates to tasks, use PUT /contacts/:contactId/tasks/:taskId or POST /contacts/:contactId/tasks to add new tasks. Always validate response data to ensure fields align with your GHL schema before automating downstream steps.
Yes. You can fetch a contact along with their tasks, notes, and appointments by calling related endpoints such as GET /contacts/:contactId, GET /contacts/:contactId/tasks, and GET /contacts/:contactId/notes. You can chain these in a single Zap or across multiple steps to assemble a complete view. Use pagination and filtering where supported to manage large sets of data efficiently.
Testing is essential before going live. Use Zapier’s test feature to simulate the trigger and verify outputs from each endpoint. Validate that data mappings, error handling, and retries behave as intended. Once satisfied, switch to live mode and monitor logs for any unexpected behavior.
Due to high volume, we will be upgrading our server soon!
