Authenticate your requests using OAuth 2.0 with your GHL developer account and securely manage access tokens.
Zapier App Connector uses OAuth 2.0 and API keys as configured in your app settings to securely authorize calls to the Contacts API.
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; contacts.write; 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
Trigger: when a new contact is created in Contacts API
Actions: create a task for the contact and apply a tag using the endpoints POST /contacts/:contactId/tasks and POST /contacts/:contactId/tags
POST /contacts/:contactId/tasks; POST /contacts/:contactId/tags
contactId, taskId, tagId
Trigger: contact update in Contacts API
Actions: update contact fields (PUT /contacts/:contactId) and reflect changes in Zapier
PUT /contacts/:contactId
contactId, updatedFields
Trigger: task marked completed in Contacts API
Actions: mark task completed (PUT /contacts/:contactId/tasks/:taskId/completed) and optionally delete finished tasks (DELETE /contacts/:contactId/tasks/:taskId)
PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId
contactId, taskId
Rapid automation setup without writing a line of code
Flexible data mapping across contacts, tasks, notes, and tags
Scalable workflows that grow with your CRM needs
A concise glossary of API terms and the data flows used in this integration.
Application Programming Interface — a set of rules that lets software systems talk to each other.
Proving identity to access secure APIs, typically via OAuth 2.0 or API keys.
A specific URL in an API that performs an action or returns data.
The data sent with an API request or returned in a response.
Create a Zap that automatically creates a welcome task, assigns tags, and adds a reminder after a new contact is added.
Sync notes from Contacts API into a notes field or activity log in your app connector.
Periodically pull business-related data via GET /contacts/business/:businessId and update related records.
Create your app, obtain client credentials, and authorize access to the Contacts API and Zapier.
Align fields for contacts, tasks, notes, and tags between the API and the connector.
Run tests in Zapier, verify data integrity, and deploy your automations.
No coding is required to start automating with the Zapier App Connector. The connector handles authentication, field mapping, and trigger/action setup in a no-code interface. For advanced logic, you can add filters or use webhooks, but you can achieve most workflows without writing code.
You can automate with endpoints such as GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, and related task/note endpoints. Choose endpoints that fit your workflow, and remember not every page needs all endpoints.
Use OAuth 2.0 with your GHL developer credentials to obtain access tokens. Rotate tokens as recommended and store credentials securely in your app settings.
Yes. Notes, tasks, and tags can be mapped between GHL and Zapier App Connector. Define fields like taskId, notesId, and tagId to ensure accurate synchronization.
Most setups finish in under 30 minutes for simple workflows. Complex automations with multiple endpoints may take longer to configure and test.
Yes, there are rate limits defined by GHL for API requests. Plan your automations accordingly and stagger requests to avoid throttling.
Endpoint definitions and examples are documented in this guide and in your developer portal. Refer to the endpoint list above for quick reference and use cases.
Due to high volume, we will be upgrading our server soon!
