Set up secure authentication for the Contacts API using OAuth 2.0 or an API token. Ensure you grant only the necessary scopes for reading contact data and related resources.
In Zapier, create or select a connection for the App Connector, enter the required client credentials, and authorize access to contacts resources. Use the minimal required permissions for your workflow.
The Contacts API endpoints cover contacts, tasks, notes, and appointments. Typical operations include listing, creating, updating, and deleting records such as GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, and related sub-resources like tasks and notes. This page highlights the endpoints most commonly used when building Zapier automations.
Trigger: A new or updated contact in GHL initiates a Zap to create or update the contact in your app and to assign or modify related tasks.
Actions: POST /contacts/ to create a contact; PUT /contacts/:contactId to update; POST /contacts/:contactId/tasks to assign tasks; PUT /contacts/:contactId/tasks/:taskId to update tasks.
Example paths: POST /contacts/ for new records; PUT /contacts/:contactId for updates; POST /contacts/:contactId/tasks for task creation; PUT /contacts/:contactId/tasks/:taskId for task updates.
Key fields: contactId, taskId, businessId. Map these to your app fields to ensure consistent synchronization.
Trigger: Changes in a contact profile prompt Zapier to pull the latest details for synchronization.
Actions: GET endpoints to fetch contact data and related resources such as /contacts/:contactId/tasks, /contacts/:contactId/notes, and /contacts/:contactId/appointments; map fields to your app.
Example paths: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments.
Key fields: contactId, businessId; maintain stable IDs for reliable syncing.
Trigger: Bulk import or scheduled batch sync to process large sets of contacts and related data.
Actions: POST /contacts/ to create multiple contacts; PUT /contacts/:contactId and POST /contacts/:contactId/tasks to assign multiple tasks; use DELETE for cleanup and POST /contacts/:contactId/tags for tagging.
Leverage sequences of endpoints for batch work: create, update, then attach tasks and notes as a batch.
Key fields: contactId, taskId, businessId, tagId; ensure mappings support batch processing.
Automate lead intake, onboarding, and follow ups without writing code.
Real time data synchronization across your apps improves accuracy and response times.
Drag and drop workflow builders enable rapid experimentation and scalable automation.
Understand API concepts such as endpoints, authentication, triggers, actions and field mappings used when integrating the GHL Contacts API with the Zapier App Connector.
An Application Programming Interface that allows software to request and exchange data with another service.
A specific URL path used to access a particular function of an API.
The process of verifying identity and permissions before allowing access to API resources.
A callback URL that receives real time notifications when events occur in a system.
Pull contact data, apply scoring rules, and route high quality leads to sales tasks automatically.
Create a new contact in your CRM and kick off welcome tasks and notes for a smooth onboarding.
Sync calendar events and send reminders automatically via Zapier after a meeting is scheduled.
Obtain credentials from the GHL account and configure the Zapier App Connector connection with the appropriate scopes.
Choose contact based triggers, map fields, and define actions in your Zap to flow data into the target app.
Run tests, validate data mappings, and deploy the automation with logging and alerts.
The integration supports OAuth 2.0 for secure user delegated access and API keys for service to service connections. Choose the method that best fits your security requirements and ensure the token has only the necessary scopes. Store credentials securely and rotate them according to your security policy.
Common endpoints include GET /contacts/:contactId to read contact data, POST /contacts/ to create, PUT /contacts/:contactId to update, and GET /contacts/:contactId/tasks to fetch related tasks. For full context you may also use notes and appointments endpoints to enrich data.
Yes. You can create and update tasks using POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId, as well as add or modify notes via the notes endpoints. Map these actions in your Zap to keep data synchronized.
Rate limits apply to API calls and depend on your GHL plan. Plan for retries and backoff in Zapier unless your workflow is near limits. If you anticipate heavy usage, consider batching requests and caching IDs where appropriate.
Use Zapier’s field mapping to align GHL contact fields with your app data structure. Map identifiers like contactId, name, email, and custom fields, then transform values if needed before sending to the target service.
Store the GHL contactId as the canonical key for each contact. Use businessId or internal IDs as secondary references for relationships like tasks and notes to avoid duplicates.
Refer to the API documentation within GHL for the most up-to-date endpoint list. Updates to endpoints and permissions are reflected in the changelog and the App Connector release notes.
Due to high volume, we will be upgrading our server soon!
