Access to the Contacts API requires secure authentication using the provided credentials (scope: contacts.readonly). Use OAuth or an API key as issued by your GHL account to authorize requests.
In Zapier, create a new app connection using your GHL credentials. Configure the OAuth flow or API key, test the connection, and save. This ensures requests to the Contacts API are securely authenticated.
GET /contacts/:contactId — fetch a single contact; GET /contacts/:contactId/tasks — retrieve tasks for a contact; GET /contacts/:contactId/tasks/:taskId — get a specific task; GET /contacts/:contactId/notes — list notes; GET /contacts/:contactId/notes/:id — get a note; GET /contacts/:contactId/appointments — fetch appointments; GET /contacts/ — list contacts; GET /contacts/business/:businessId — list contacts by business; POST /contacts/ — create a contact; PUT /contacts/:contactId — update a contact; DELETE /contacts/:contactId — delete a contact; POST /contacts/:contactId/tasks — create a task; PUT /contacts/:contactId/tasks/:taskId — update a task; PUT /contacts/:contactId/tasks/:taskId/completed — mark a task completed; DELETE /contacts/:contactId/tasks/:taskId — delete a task; POST /contacts/:contactId/tags — add tags to a contact.
Trigger: A contact is updated in GHL, then fetch the latest data via GET /contacts/:contactId and push updates to Zapier workflows.
Actions: Update contact fields in downstream apps, create tasks, or add notes based on the pulled data.
Method/path example: GET /contacts/:contactId to pull data; PUT /contacts/:contactId to update; POST /contacts/ to create a new contact.
Key fields: contactId, name, email, phone, tags.
Trigger: A new task is created in Zapier and linked to a GHL contact, using POST /contacts/:contactId/tasks.
Actions: Update task status (completed), add due dates, or attach notes via GHL endpoints.
Method/path examples: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed.
Key fields: contactId, taskId, title, dueDate, status.
Trigger: Add a note or tag to a contact via GHL, then reflect changes in Zapier.
Actions: Post new notes and assign tags using POST /contacts/:contactId/notes and POST /contacts/:contactId/tags.
Method/path examples: POST /contacts/:contactId/notes; POST /contacts/:contactId/tags.
Key fields: contactId, noteId, tagId.
Automate repetitive contact workflows without writing a line of code.
Save time with real-time data sync and event-driven actions.
Maintain clean, centralized data across GHL and connected apps.
A quick glossary of terms and concepts to help you design reliable integrations.
Application Programming Interface: a set of endpoints and rules that let apps talk to each other.
A person stored in your GHL Contacts database with associated data like name, email, and phone.
A specific URL and HTTP method used to perform an action against an API.
An actionable item linked to a contact, such as follow-up, call, or email task.
Set up triggers to push updates to GHL and pull the latest data back into Zapier workflows.
Automatically create and track tasks in GHL when new users join via another app connected to Zapier.
Leverage notes and tags to categorize and segment contacts for tailored campaigns.
Obtain your API key or configure OAuth in GHL, then register the credentials in Zapier.
Select the appropriate endpoints (e.g., GET /contacts/:contactId, POST /contacts/:contactId/tasks) and define Zapier triggers and actions.
Run tests to verify data flow, then enable the integration for your team.
Use OAuth 2.0 or an API key as provided by GHL. Ensure your token includes the required scope (e.g., contacts.readonly) and attach it to your request headers. Always test connections in a secure environment before going live. In Zapier, you can store credentials securely and reuse them for multiple actions.
No-code is a core feature of the Zapier App Connector. You can map triggers and actions to API endpoints without writing code. Some advanced scenarios may require small custom fields or scripts, but for most workflows you can build everything visually.
GET /contacts/ returns a list of contacts with pagination. Use filters for business or status if supported by your GHL account. For large datasets, implement pagination logic in Zapier to iterate through pages.
Use POST /contacts/:contactId/notes to add notes to a contact. Include content in the request body and associate it with the correct contactId. Notes can be retrieved with GET /contacts/:contactId/notes.
Call POST /contacts/:contactId/tags to assign one or more tags. Manage tag IDs in your system and ensure the contactId matches the intended record.
Yes. Use PUT /contacts/:contactId/tasks/:taskId/completed to mark a task as finished. You can also update task fields with PUT /contacts/:contactId/tasks/:taskId.
Refer to the API documentation or your GHL account dashboard to view the full list of endpoints. Endpoints may vary by plan and permissions.
Due to high volume, we will be upgrading our server soon!
