Obtain credentials for the GHL API via OAuth or an API key and configure them in Zapier to enable secure access to your contacts data.
Authorize the Zapier App Connector in your GHL account and complete the OAuth flow to enable automation between GHL and connected apps.
Available endpoints 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.
Use GET /contacts/:contactId to pull contact data and trigger downstream workflows when a contact is updated or a new contact is added.
Actions can include fetching related tasks, notes, and appointments to populate downstream apps.
Primary method: GET /contacts/:contactId (read only) to begin automation.
Key fields: contactId, email, name, lastInteractionDate.
Trigger on form submission in your app to create a new contact in GHL via POST /contacts/.
Actions: create a new contact, set tasks or notes, sync fields to other apps.
POST /contacts/ is the creation path.
Required: name, email; optional: phone, businessId.
Trigger when a contact is updated in GHL to sync changes in connected apps.
Actions: update contact via PUT /contacts/:contactId, update related tasks via PUT /contacts/:contactId/tasks/:taskId, or mark tasks completed.
PUT /contacts/:contactId is used to update core fields.
Key fields: contactId, updated fields such as name, email, phone.
Automate repetitive tasks without writing code.
Create multi step workflows that connect GHL with CRM, email, and collaboration tools.
Scale operations quickly with ready to use triggers and actions.
Key elements include endpoints, authentication, triggers, actions, and data fields used to connect GHL with Zapier.
A URL path that executes a specific operation on the GHL API (GET, POST, PUT, DELETE).
An event in GHL that starts a Zapier workflow.
Method to verify access, usually OAuth or API key.
A data element transferred to or from the API, such as name, email, etc.
When a new contact is added in GHL, Zapier creates a task in the related project.
Push notes to Notion, Slack, or your team wiki for quick reference.
On form submission, update contact data in GHL via the API.
Select GHL Contacts API as the trigger and map fields to your destination app.
Authorize in the Zapier OAuth flow and select the GHL account.
Choose actions like create contact, add task, or write notes.
The GHL Contacts API exposes endpoints for reading and managing contact data within your GHL account. It supports retrieving a single contact, their tasks, notes, and appointments, as well as creating new contacts and updating existing ones. This enables you to build automated flows that respond to contact events and keep systems in sync. By using Zapier App Connector, you can trigger actions based on contact events and route data to your CRM, email, or project management tools.
Authorization can be achieved via OAuth for secure, token-based access, or via an API key if your setup requires it. In Zapier, configure the GHL account with OAuth so workflows can access only the necessary data. If your organization uses API keys, ensure the key has the appropriate scopes such as contacts.readonly or contacts.write as needed.
Reading contacts is supported through endpoints like GET /contacts/:contactId and GET /contacts/. You can also fetch related data such as tasks, notes, and appointments for a given contact. This makes it easy to assemble a complete picture of a contact in downstream apps. The endpoints are designed to be combined in multi-step Zaps for robust automation.
Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. You can also attach tasks and notes via their respective endpoints. The API supports typical CRUD operations to keep data synchronized across systems without manual data entry.
The supported authentication methods are OAuth and API key based. OAuth is preferred for secure, user-consented access, while API keys may be used in trusted environments. Always follow best practices to protect credentials and restrict scopes to the minimum required for the workflow.
No coding is required to use the integration in many cases. Zapier App Connector provides a no-code way to connect GHL Contacts API to hundreds of apps. For advanced scenarios, you can customize mappings and use multi-step Zaps to achieve complex automation.
To test a Zapier workflow, run a test trigger to fetch sample contact data, verify field mappings, and perform a test action such as creating a dummy contact or note. Use Zapier’s built in testing tools and monitor the task history to ensure the automation behaves as expected.
Due to high volume, we will be upgrading our server soon!
