The Contacts API uses OAuth 2.0 for secure access. Obtain client credentials, request tokens, and refresh tokens automatically within Zapier App Connector to maintain continuous connectivity.
In Zapier, configure OAuth scopes to cover reads and writes for contacts, tasks, notes, and tags. Token storage is handled by Zapier to keep credentials secure and rotating as needed.

Zapier Trigger: Retrieve a contact by ID
Pull contact data into workflows, update related records, or sync with marketing campaigns
GET /contacts/:contactId
contactId, fields to return (name, email, phone)
Zapier Trigger: New contact from another system
Create the contact in GHL, then map resulting contactId back to subsequent actions
POST /contacts/
email, firstName, lastName, phone, tags
Zapier Trigger: New task for a contact
Create a task under the specified contact, then update status as needed
POST /contacts/:contactId/tasks
contactId, taskName, dueDate, status

Glossary of terms and core concepts for mapping endpoints, authentication flows, and data fields between the GHL Contacts API and the Zapier App Connector.
A standard for token-based authorization used to grant apps secure access without exposing user credentials.
A specific URL in an API that performs an action or returns data, such as retrieving a contact.
A method for event-driven updates where one app notifies another when something happens.
A unit of work attached to a contact, such as a to-do item or reminder.
Capture form submissions, create a contact in GHL, and tag them for onboarding, all without writing a line of code.
When a task is created or updated, trigger reminders and update related notes.
Sync notes from your tools to GHL contacts to maintain a complete history.
Set up OAuth credentials in the Zapier app and grant necessary scopes.
Choose the endpoints you need, map contact fields, and set business rules.
Run end-to-end tests, review logs, and deploy to production with confidence.
The Contacts API uses OAuth 2.0 token-based authentication. In Zapier App Connector, you configure your OAuth client, authorize access, and Zapier manages token refreshes so your automations stay connected without manual re-auth. If you prefer API keys for test environments, you can generate scoped keys and rotate them regularly, but OAuth provides broader and safer access for ongoing integrations.
Common endpoints include GET /contacts/:contactId to read contact data, POST /contacts/ to create new contacts, and POST /contacts/:contactId/tasks to assign tasks. These enable onboarding, task management, and data synchronization across apps.
Yes. Use POST /contacts/ to create a new contact and PUT /contacts/:contactId to update details. For task management, you can POST /contacts/:contactId/tasks to create tasks, and PUT /contacts/:contactId/tasks/:taskId to update them.
Map fields from source apps to the corresponding GHL contact fields in Zapier actions. Use the field mapping UI to ensure name, email, phone, and custom fields sync correctly and validate data types.
Rate limits depend on your GHL plan and Zapier plan. Plan ahead by batching requests and handling retries with exponential backoff. Logging and alerts help catch throttling early.
Zapier retries failed actions based on configured settings. If failures persist, you’ll receive a notification and can inspect error details to adjust mappings or endpoints.
Yes. Use endpoints like GET /contacts/ with query filters or specify contactId for direct retrieval. Combine with tasks or notes endpoints to build richer workflows.
Due to high volume, we will be upgrading our server soon!
