GHL uses secure OAuth 2.0 tokens with the scope needed for contacts. When you connect via Zapier, you’ll configure a GHL connection that stores tokens and refreshes them automatically, ensuring uninterrupted access to endpoints like GET /contacts/:contactId.
Zapier manages OAuth 2.0 client credentials and securely stores access tokens. During setup, select the Contacts API as the resource to authorize and grant the necessary scope (e.g., contacts.readonly) to enable reading and automating contact data.
1) GET /contacts/:contactId — Retrieve a single contact by ID 2) GET /contacts/:contactId/tasks — List tasks for a contact 3) GET /contacts/:contactId/tasks/:taskId — Get a specific task for a contact 4) GET /contacts/:contactId/notes — List notes for a contact 5) GET /contacts/:contactId/notes/:id — Get a specific note for a contact 6) GET /contacts/:contactId/appointments — List appointments for a contact 7) GET /contacts/ — List all contacts 8) GET /contacts/business/:businessId — List contacts by business ID 9) contacts.write — API scope for writing contact data 10) POST /contacts/ — Create a new contact 11) PUT /contacts/:contactId — Update a contact 12) DELETE /contacts/:contactId — Delete a contact 13) POST /contacts/:contactId/tasks — Create a task for a contact 14) PUT /contacts/:contactId/tasks/:taskId — Update a task for a contact 15) PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed 16) DELETE /contacts/:contactId/tasks/:taskId — Delete a task for a contact 17) POST /contacts/:contactId/tags — Add tags to a contact
Trigger when a contact is created or updated in GHL, then pull fresh data into Zapier for downstream apps.
Actions: fetch contact details (GET /contacts/:contactId) and push updates to your CRM, email platform, or support tool.
GET /contacts/:contactId
contactId, email, firstName, lastName
Trigger when a new task is created for a contact in GHL.
Actions: create task (POST /contacts/:contactId/tasks), list tasks (GET /contacts/:contactId/tasks), update or complete tasks (PUT /contacts/:contactId/tasks/:taskId or PUT /contacts/:contactId/tasks/:taskId/completed).
POST /contacts/:contactId/tasks
contactId, taskId, name, dueDate, status
Trigger when a tag is added to a contact in GHL, enabling downstream routing.
Actions: add tag to contact (POST /contacts/:contactId/tags), search by tag, and trigger campaigns.
POST /contacts/:contactId/tags
contactId, tag
Automate repetitive contact workflows without writing code, using ready-made triggers and actions.
Centralize data flow between GHL and your apps with reliable, repeatable automations.
Scale CRM automation with reusable Zap templates and clean data mappings between systems.
Understand the core elements (contacts, tasks, notes, tags) and the processes (authentication, endpoints usage, data mapping) that drive GHL + Zapier integrations.
An individual in GHL with associated fields like name, email, and company.
An action item linked to a contact, such as a follow-up or appointment.
A memo or comment added to a contact’s profile for context.
A label used to categorize or segment a contact for targeted workflows.
Capture leads from landing pages and immediately create a new contact in GHL via POST /contacts/, then trigger a welcome task or email sequence.
Push ticket updates into the contact notes (GET /contacts/:contactId/notes, POST /notes) to maintain a complete history.
Assign tags from support outcomes or form responses to trigger tag-based automations and campaigns.
Create or select a OAuth 2.0 client in Zapier to authenticate with the GHL Contacts API (scope: contacts.readonly).
Use the endpoint list (GET /contacts/:contactId, GET /contacts/) to verify access and data mapping.
Create a Zap that triggers on new or updated contacts and routes data to marketing, support, or analytics apps.
To connect, you’ll configure OAuth 2.0 credentials for the GHL API within Zapier and grant the required scope (contacts.readonly). This ensures Zapier can read contact data securely. If you’re integrating data into other apps, you may add write permissions (via the contacts.write scope) where allowed. Always store tokens securely and rotate them as recommended by OAuth best practices. If you’re using a test environment, start with GET /contacts/:contactId to verify authentication and then move to more advanced actions as you validate data mappings.
Key endpoints include listing contacts (GET /contacts/), retrieving a specific contact (GET /contacts/:contactId), and managing related data like tasks (GET/POST/PUT/DELETE /contacts/:contactId/tasks). You’ll also find notes, appointments, and tags endpoints useful for building end-to-end automations. Use POST for creating, GET for reading, PUT for updating, and DELETE for removal as needed.
No heavy coding is required for most automations. Zapier provides a visual workflow builder where you map fields from GHL to other apps. For complex logic, you can use built-in filters, paths, and formatter steps, along with multi-step Zaps that chain several endpoints together.
Authentication is handled via OAuth 2.0. In Zapier, you connect your GHL account, authorize access, and Zapier stores tokens securely. Regularly review connected accounts and scopes to ensure only the required permissions are granted.
Yes. You can push updates back to GHL using endpoints like PUT /contacts/:contactId and POST /contacts/:contactId/tasks. When designing your Zap, ensure data consistency by validating IDs and using idempotent steps where possible.
Rate limits vary by endpoint and plan. If you hit limits, implement exponential backoff in Zapier, batch requests where possible, and stagger polling to avoid throttling. Consider using webhooks where available to minimize polling overhead.
The endpoint list is provided in this page as a reference. You can also explore GHL API documentation within the developer portal and use the ENDPOINTLIST section here to quickly locate common operations like contacts, tasks, notes, and tags.
Due to high volume, we will be upgrading our server soon!
