To access the Contacts API, obtain your API credentials from the GHL developer portal and authorize the integration. Use OAuth 2.0 with the scope set to contacts.readonly to begin; you can request additional scopes as needed.
In Zapier, establish an OAuth 2.0 connection for the Zapier App Connector. Store refresh tokens securely and ensure the connection can be re-authenticated when tokens expire.
GET /contacts/:contactId — fetch a single contact; GET /contacts/:contactId/tasks — fetch tasks for a contact; GET /contacts/:contactId/tasks/:taskId — fetch a specific task; GET /contacts/:contactId/notes — fetch notes; GET /contacts/:contactId/notes/:id — fetch a note; GET /contacts/ — list contacts; GET /contacts/business/:businessId — list contacts by business; POST /contacts/ — create; PUT /contacts/:contactId — update; DELETE /contacts/:contactId — delete; POST /contacts/:contactId/tasks — create a task; PUT /contacts/:contactId/tasks/:taskId — update a task; PUT /contacts/:contactId/tasks/:taskId/completed — mark complete; DELETE /contacts/:contactId/tasks/:taskId — delete task; POST /contacts/:contactId/tags — add tags
Trigger: when a contact is retrieved or updated; you can pull in related tasks and notes for a complete view.
Actions: Get contact, Get contact tasks, Get contact notes
Paths: GET /contacts/:contactId and GET /contacts/:contactId/tasks
Key fields: contactId, taskId, noteId
Trigger: contact record changes; then create related tasks.
Actions: PUT /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId
Paths: PUT /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Trigger: new contact created or imported; ready for tagging.
Actions: POST /contacts/, POST /contacts/:contactId/tags
Paths: POST /contacts/; POST /contacts/:contactId/tags
Key fields: contactId, tagId
No coding required to automate data flows between GHL and your apps.
Drag-and-drop automation in Zapier to design multi-step workflows.
Real-time data syncing with robust error handling and retries.
Understand the main elements: endpoints, triggers, actions, fields, and responses; mapping between GHL Contacts API and Zapier.
API stands for Application Programming Interface – a set of endpoints and data formats that allow apps to communicate.
OAuth 2.0 is an authorization framework that enables secure access to APIs using tokens.
An individual URL and method for performing an action or retrieving data in an API.
A callback URL that apps can notify when events occur.
Automatically sync contact changes from GHL to your CRM, email marketing, and support tools via Zapier.
Capture new leads from forms and create follow-up tasks and campaigns across apps.
Tag and segment contacts automatically based on interactions, increasing targeting precision.
Create an app in the GHL developer portal, obtain client_id and client_secret, and specify a redirect URL for OAuth.
In Zapier, set up a new connection, select OAuth, and provide the client credentials and required scopes like contacts.readonly.
Test API calls, map response fields to Zapier output, and enable automation across your stack.
No coding is required to start. The Zapier App Connector provides a no-code interface to configure triggers, actions, and searches. You can set up automations by selecting endpoints and mapping fields using simple UI elements. For more complex logic, you can chain steps, add filters, and use paths without writing code.
You can access core contact data (name, email, phone), plus related items like tasks, notes, appointments, and tags via the Contacts API. You can create, update, or delete records using the corresponding HTTP methods. Field availability depends on your GHL plan and the API permissions granted.
Authentication uses OAuth 2.0 with tokens. Zapier can manage token refresh automatically. Keep credentials secure and limit scopes to what you need (for example, contacts.readonly). If tokens expire, re-authentication is required.
Yes. Use the connection test feature in Zapier to verify endpoints, authentication, and field mappings before going live. This helps confirm permissions and data formats.
Commonly used endpoints include GET /contacts/:contactId to retrieve a contact, GET /contacts/:contactId/tasks for associated tasks, POST /contacts/ to create, and POST /contacts/:contactId/tags to tag a contact. These cover most read/write automation scenarios.
Use Zapier’s field mapping UI to align GHL fields with your target app fields. Test with sample data, adjust types, and validate required fields. Save mappings and run a few test tasks to ensure accuracy.
Rate limits depend on your GHL plan and API access. Check response headers for quota information, and contact support if you anticipate higher usage. Implement retry logic and exponential backoff to handle temporary limits.
Due to high volume, we will be upgrading our server soon!
