To use the Contacts API in the Zapier App Connector you will obtain an access token with the required scope contacts.readonly and store it securely. This ensures you can read contact data without writing changes.
In Zapier create a new connection for the Contacts API. Provide the credentials, test the connection, and approve the requested permissions to enable data sync.
The following endpoints are available for integration: 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 operation endpoints such as contacts.write, 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 and POST /contacts/:contactId/tags. These endpoints cover reading and basic management of contacts, tasks, notes and related data within the GHL Contacts API.
Trigger: when a specific contact is requested or updated via GET /contacts/:contactId
Actions: sync contact fields to APPNAME, update CRM records or create related tasks
GET /contacts/:contactId
Key fields: contactId, name, email, phone, customFields
Trigger: retrieve tasks for a contact via GET /contacts/:contactId/tasks
Actions: bring task data into APPNAME and update task statuses as needed
GET /contacts/:contactId/tasks
Key fields: taskId, taskName, status, dueDate
Trigger: fetch notes for a contact via GET /contacts/:contactId/notes
Actions: sync notes to APPNAME and attach to the contact record
GET /contacts/:contactId/notes
Key fields: noteId, note, createdAt
Automate data flow without writing code and leverage ready made endpoints
Keep contact data in sync across apps in real time without manual exports
Build custom workflows using existing endpoints to fit your processes
Key elements and processes explained for integrating GHL Contacts API with Zapier App Connector
A specific URL and HTTP method used to access or modify data in an API
The process of proving identity to gain access to the API
A callback URL that receives event notifications from an API
Permissions granted to an app to access specific data or perform actions
Use GET /contacts/:contactId and POST /contacts/:contactId/tasks to automatically create tasks in APPNAME when a new contact is added
Map GET /contacts/:contactId/notes to your notes app to automatically store contact notes
Aggregate data from contacts, tasks and notes into a unified dashboard in APPNAME
Obtain API credentials for the Contacts API and configure the connection in Zapier
Select GET endpoints and map fields to APPNAME
Run tests to confirm data flows correctly and deploy to live workflows
No heavy coding is required. The Zapier App Connector provides a configurable interface to connect to the GHL Contacts API. You can map fields and set up basic workflows without writing code. For more advanced logic you can add filters and multi step automations. The goal is to make data flow simple and repeatable across your apps.
You can access core contact data such as name and contact details, plus related data like tasks, notes and appointments depending on the endpoints you enable. With the scope set to contacts.readonly you can read data but not modify it by default.
Authentication is handled by creating a connection in Zapier that uses your GHL credentials. You will typically obtain an access token with the required scope and set it in the Zapier connector. Always keep credentials secure and rotate tokens as recommended.
Webhooks are supported in many workflows. If you need event driven updates you can configure triggers that react to changes in GHL or rely on Zapier polls where webhooks are not available. Review endpoint capabilities to choose the best approach.
Yes. You can configure triggers in Zapier to react to changes from GHL data. Real time updates depend on your trigger and the endpoints used; some flows can approach real time with short polling intervals.
Rate limits are determined by the GHL API. Typical quotas apply and are documented in the API docs. If you hit limits, stagger requests or implement caching and batch processing in your workflows.
API documentation is available in the GHL developer portal. The page referenced on this site includes endpoint descriptions, authentication steps and usage examples to get you started with the Contacts API.
Due to high volume, we will be upgrading our server soon!
