Learn how to securely authenticate using your API key or OAuth flow to grant access to the GHL Contacts API through the connector.
Configure OAuth2 or API key-based authentication in the connector to securely access endpoints such as GET /contacts/:contactId and POST /contacts/.
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; GET /contacts/; POST /contacts/:contactId/tasks; POST /contacts/:contactId/tags; PUT /contacts/:contactId; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId; DELETE /contacts/:contactId
Trigger events when a contact is created or updated using the API key path, enabling fast automation setup in Zapier.
Actions include creating or updating contacts, adding tasks, posting notes, and scheduling appointments from Zapier.
Example methods: GET /contacts/:contactId, POST /contacts/
Key fields: contactId, businessId, taskId, noteId, appointmentId
Trigger events when a contact changes via OAuth-enabled flow, keeping data fresh across apps.
Actions include listing and retrieving contacts, tasks, notes, and creating new records from Zapier.
Example methods: GET /contacts, GET /contacts/:contactId, POST /contacts/:contactId/tasks
Key fields: contactId, taskId, noteId, eventType
Trigger on webhook payloads when contacts, tasks, or notes are updated.
Actions include parsing payloads, mapping fields, and kicking off downstream automations in Zapier.
Webhook examples: POST /webhook/contacts, POST /webhook/tasks
Key fields in payload: contactId, eventType, timestamp
No coding required—build automations with a visual workflow designer.
Rapid setup with prebuilt actions for contacts, tasks, notes, and appointments.
Centralized data and real-time sync across connected apps.
Understand REST endpoints, authentication methods, data fields, and best practices for integrating the GHL Contacts API with the Zapier App Connector.
Application Programming Interface: a set of endpoints to access resources programmatically.
Authorization framework that allows secure access to resources without sharing credentials.
A mechanism for apps to send real-time data to other apps via HTTP POST.
Specific URLs that perform actions on resources in an API.
Create a Zap that postpones a task and automatically notifies the relevant team or owner when the status changes.
Use filters to segment contacts and trigger tailored outreach after postponement.
Log postponement events in notes or a dedicated history to support compliance.
Grant the Zapier App Connector access to your GHL Contacts API account.
Choose API Key or OAuth 2.0 and map fields for endpoints like GET /contacts/:contactId.
Build a workflow to postpone a contact’s task and update related records automatically.
A developer account isn’t strictly required if you use the Zapier App Connector with API key or OAuth-based authentication. However, having access to your GHL account credentials and proper permissions will help you configure connections and test endpoints. Ensure you follow security best practices when storing keys or tokens. Two-factor authentication and scoped access reduce risk.
Supported methods include API Key-based auth and OAuth 2.0. API Keys are simple to implement for basic tasks, while OAuth 2.0 provides secure delegated access for more complex automations. Choose the method that aligns with your security needs and workflow requirements, then map fields accordingly in Zapier.
Bulk updates can be performed by looped actions in Zapier or by using batch endpoints if available. For large datasets, consider paging through results (GET /contacts) and applying updates in batches to minimize rate-limit impacts. Always test on a subset before full rollout.
Postponing a task typically involves updating the task status via PUT /contacts/:contactId/tasks/:taskId/completed or adjusting the due date. Use a Zap to trigger on specific events and call the appropriate endpoint with the taskId and new status or date.
Yes. Webhooks can deliver real-time updates about contacts, tasks, notes, and appointments. Configure your Zapier webhook receiver to listen for relevant event types and process payloads to trigger downstream automations.
Rate limits depend on your GHL plan and API usage. Monitor response headers for quota information, implement exponential backoff, and batch requests where possible to stay within limits while maintaining reliability.
Endpoint details are documented in the Contacts API section of the GHL API reference. You can also view example calls and required fields for each endpoint (e.g., GET /contacts/:contactId, POST /contacts/).
