Authenticate with a token that carries the contacts.readonly scope. Use your GHL API credentials to authorize the Zapier App Connector and grant read‑only access to contact data.
In Zapier, connect the app once to authorize data access. The connector securely uses tokens to access Contacts API data, with no coding required.
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
Trigger: Retrieve a contact via GET /contacts/:contactId when new data is available or a contact is updated.
Actions: fetch contact details, pull related tasks and notes, and attach any upcoming appointments for downstream workflows.
GET /contacts/:contactId
Key fields: contactId, name, email, phone, status
Trigger: List all contacts using GET /contacts/ to populate dashboards or bulk actions.
Actions: iterate over each contact, map fields, and feed into CRMs, spreadsheets, or downstream apps.
GET /contacts/
Key fields: contactId, name, email, phone, status
Trigger: Update contact tags via POST /contacts/:contactId/tags when tagging is required.
Actions: apply tag(s) to the contact, filter by tag, and propagate updates to connected apps.
POST /contacts/:contactId/tags
Key fields: contactId, tags
Automate data flow between your CRM and apps without writing code.
Create multi-step workflows that trigger actions across platforms on a schedule or event.
Keep contacts, tasks, notes, and appointments synchronized with minimal setup.
This section defines core terms used in the guide: API endpoints, authentication scopes, triggers, actions, and data mapping.
GHL API is the programming interface provided by GHL to access contacts, tasks, notes, appointments, and more from external apps.
A no‑code bridge that connects GHL APIs to apps like Zapier to automate workflows.
The permissions granted for an access token, such as ‘contacts.readonly’.
A specific URL path used to access a resource in the API.
Capture form submissions in your site and push new contacts into GHL via the Contacts API, then automatically sync related tasks and notes.
When a note is added or updated in a contact, send it to your knowledge base app to keep records current.
Automatically create reminders when a contact’s tasks are due to ensure timely follow-up.
Open Zapier, select the Contacts API, and authorize the connection to grant access to your contact data.
Choose a trigger like ‘New or Updated Contact’ to start your workflow.
Map fields and set up downstream actions to run when the trigger fires.
The integration uses secure token-based authentication with controlled scopes to limit access to only what you need. Always use HTTPS and keep tokens confidential. Regularly review app permissions in Zapier and revoke access if an integration is no longer needed. Second, follow best practices for handling sensitive contact data within your automation flows to maintain compliance and data integrity.
The Contacts API provides access to core contact data (name, email, phone, etc.), tasks associated with contacts, notes, and appointments. Depending on the endpoint, you can read or write certain data, always respecting the scope defined (e.g., contacts.readonly). Use the endpoints to pull, map, and push data into your other tools.
No traditional coding is required. Zapier App Connector provides a visual workflow builder to configure triggers, actions, and data mappings. Some understanding of how data fields map between apps helps, but you can build powerful automations with drag-and-drop steps.
Yes. You can update a contact’s tasks and notes via respective endpoints (e.g., POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes). When configured in a Zap, changes in one app can trigger updates in another. Ensure you have write permissions where needed.
For a basic workflow, you typically need GET /contacts/:contactId to fetch data, GET /contacts/ to list contacts, and POST /contacts/:contactId/tags to update tags. These endpoints cover retrieval, listing, and tagging—core operations for many automations.
Authentication is handled in Zapier by connecting the app and granting access once. The connector uses tokens with the necessary scope (such as contacts.readonly) to authorize requests without exposing credential details in your workflows. If the connection is revoked, automations will stop until reauthorized.
You typically need the ‘contacts.readonly’ scope for most viewing workflows. If you plan to modify data (creating or updating contacts, tasks, or notes), request broader scopes aligned with your use case and follow least-privilege practices to minimize risk.
Due to high volume, we will be upgrading our server soon!
