Authenticate to GHL using OAuth 2.0 tokens or a personal API key. Store credentials securely and configure your Zapier connection to refresh tokens automatically.
Zapier handles authentication within the app connection. Use OAuth if supported, or provide API keys in secure fields. Test the connection to confirm access scopes such as contacts.readonly are granted.
GET /contacts/:contactId Retrieve a single contact; GET /contacts/:contactId/tasks List tasks for a contact; GET /contacts/:contactId/tasks/:taskId Retrieve a specific task; GET /contacts/:contactId/notes Retrieve notes for a contact; GET /contacts/:contactId/notes/:id Retrieve a specific note; GET /contacts/:contactId/appointments Retrieve appointments; GET /contacts/ Retrieve all contacts; GET /contacts/business/:businessId Retrieve contacts for a business; contacts.write; POST /contacts/ Create a new contact; PUT /contacts/:contactId Update a contact; DELETE /contacts/:contactId Delete a contact; POST /contacts/:contactId/tasks Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId Update a task; PUT /contacts/:contactId/tasks/:taskId/completed Mark a task as completed; DELETE /contacts/:contactId/tasks/:taskId Delete a task; POST /contacts/:contactId/tags Add tags to a contact.
Trigger: when a contact is created or updated in GHL so Zapier can sync records instantly.
Actions: find or create contacts, update contact fields, attach tasks, notes, and tags.
Example path: GET /contacts/:contactId to fetch data, then use related resources such as /contacts/:contactId/tasks to pull tasks.
Key fields to map: contactId, firstName, lastName, email, phone, tags, notes
Trigger for bulk updates can be configured via scheduled or batch processes to keep datasets aligned.
Actions: create and update contacts, add tasks, notes, and tags in bulk.
Paths: POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks
Key fields: contactId, businessId, fields for batch updates
Trigger via data returned from endpoints to drive downstream steps.
Actions: read, write, and manage data across contacts, tasks, notes, and tags using listed endpoints.
Paths include GET, POST, PUT, DELETE across the 17 endpoints listed.
Key fields: contactId, taskId, id for notes, businessId
Automate complex CRM flows without writing code
Link contacts, tasks, notes, and appointments across apps
Rapid deployment with testable steps in Zapier
Understand the core elements: API endpoints provide actions, triggers initiate workflows, authentication secures access, scope defines what you can do, and data mapping connects fields across apps.
A specific URL path that performs an action such as retrieving or updating data in the GHL Contacts API.
The process of proving identity and granting access to the API, typically via OAuth tokens or API keys.
An event in GHL or Zapier that starts a workflow or action in your automation.
A concrete operation performed by a Zapier step, such as create or update of a contact or task.
Set up a Zap to create onboarding tasks whenever a new contact enters GHL, keeping kickoff steps organized.
Automatically attach support notes to the contact timeline in GHL for a complete history.
Use tags in Zapier to segment contacts and trigger campaign-specific automations in GHL.
Obtain OAuth tokens or API keys for both GHL and Zapier.
Configure triggers and actions using the 17 endpoints listed above.
Run end-to-end tests to ensure data sync works across apps before going live.
The GHL Contacts API lets you read and manage contact data, tasks, notes, and appointments. In Zapier, you can trigger workflows when a contact is created or updated and perform actions such as creating tasks or updating fields.
No coding is required. Use prebuilt Zap templates and the App Connector to assemble your automation visually with triggers and actions.
Authentication uses OAuth tokens or API keys. Store credentials securely and connect the GHL and Zapier accounts in your integration setup.
For basic syncing, start with GET /contacts/:contactId to retrieve contacts and POST /contacts/ to create new ones, then add related endpoints for tasks and notes as needed.
Yes. You can update contacts with PUT /contacts/:contactId and manage tasks with POST, PUT, and DELETE on /contacts/:contactId/tasks.
Yes, there are no code templates and step-by-step guides to help you build a starter workflow quickly.
The endpoint list and parameters are available in the developer docs within the GHL API reference; the content above highlights the key endpoints and usage.
Due to high volume, we will be upgrading our server soon!
