Authenticate requests to the Contacts API using OAuth 2.0 tokens and/or an API key provided in your GHL developer settings. Store credentials securely and rotate credentials regularly.
Connect Zapier to the Contacts API by granting OAuth access or supplying a dedicated API token in your Zapier app credentials. Follow the on-screen prompts to authorize the connection.
The following endpoints are available for managing contacts, notes, tasks, and appointments. Use these as reference when building Zapier workflows to automate data flow between GHL and your apps.
Trigger: New or Updated Contact in GHL starts a Zapier workflow.
Actions: Create or Update Contact in GHL via /contacts/ and /contacts/:contactId, attach notes, and schedule tasks.
POST /contacts/ (create) and PUT /contacts/:contactId (update)
Key fields: email, firstName, lastName, phone, status
Trigger: Tasks for a contact are created or updated in GHL.
Actions: Create or update tasks in Zapier, update status, and push completion data back to GHL.
GET /contacts/:contactId/tasks
Key fields: taskId, title, dueDate, status
Trigger: Notes are added or updated for a contact in GHL.
Actions: Create or update notes in Zapier and attach to the corresponding contact record.
GET /contacts/:contactId/notes
Key fields: id, noteId, content, createdDate
Eliminate manual data entry by automating contact updates across systems.
Build multi-step workflows without coding to keep data in sync across apps.
Rapidly deploy integrations that scale with your business without heavy development.
Key elements include endpoints, triggers, actions, and the data fields that map between GHL and Zapier.
A specific URL path you call to perform a function in the GHL Contacts API.
An event in a source app that starts a Zapier workflow.
The operation Zapier performs in response to a trigger (e.g., create a contact, add a note).
The API route used to access a resource (GET, POST, PUT, DELETE) with the resource path.
Capture new form data and automatically create or update a contact in GHL via the Contacts API, then trigger a welcome email in Zapier.
When a contact is updated in GHL, push a notification to Slack or Teams via Zapier.
Store chat transcripts or meeting notes as notes on the GHL contact using the API and Zapier.
Step 1: In Zapier, add a new connection and authorize access to your GHL Contacts API account.
Step 2: Choose a trigger (for example, New Contact) and corresponding actions (such as Create Contact or Add Notes) for your Zap.
Step 3: Run tests, enable the Zap, and monitor the workflow for retries and errors.
The GHL Contacts API lets you read and manage contact data, notes, tasks, and appointments. It enables your apps to create, update, or fetch records efficiently. In Zapier, you can trigger actions when a contact is created or updated and pass data to other tools in your workflow. This combination powers no-code automations across your stack.
You’ll typically need appropriate OAuth scopes or an API key from your GHL account. Grant Zapier access in your GHL developer settings, and select the necessary scopes (for example, read or write). The exact requirements depend on whether you only read data or also update records.
For common workflows, start with GET /contacts/:contactId to fetch a contact, POST /contacts/ to create, PUT /contacts/:contactId to update, and GET /contacts/:contactId/tasks to load tasks. For notes, use GET /contacts/:contactId/notes and POST /contacts/:contactId/notes if available in your setup. Adapt based on what your Zapier workflow needs.
Yes. You can chain triggers and actions so a single Zap can update a contact and create or modify related tasks or notes. This allows cohesive workflows across GHL and other apps without switching tools.
Connections are secured using standard API security practices, including OAuth tokens and encrypted transmission. Rotate credentials regularly and limit scopes to the minimum needed for your use case.
If you need more fields, map them in Zapier’s data mapping step and ensure the fields exist on the GHL side. You may need to expose custom fields in GHL or use default fields that align with your Zapier trigger and action steps.
The endpoint list and details are summarized in this page under the Endpoints section. For full documentation, refer to your GHL API docs and the API reference provided in your developer portal.
Due to high volume, we will be upgrading our server soon!
