Authenticate to the GHL Contacts API using your API credentials. Ensure your OAuth2 flow or API key has at least read access to contacts to begin pulling data securely.
In Zapier, connect the app using OAuth2 or API key as configured in your Zapier app settings. Store credentials securely and grant the app only the permissions it needs.
Core endpoints cover reading contacts, tasks, notes, and basic CRUD operations. Examples include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId. There are additional endpoints for business, appointments, and tagging to support richer workflows.
Trigger: New or Updated Contact to pull the latest data into your workflow.
Actions: Retrieve a contact’s details, then fetch associated tasks for reporting or automation.
GET /contacts/:contactId
Key fields: contactId, name, email
Trigger: Task created or updated for a contact.
Actions: Create, update, or complete tasks linked to a contact.
POST /contacts/:contactId/tasks
Key fields: contactId, taskId, title
Trigger: Notes added or updated for a contact.
Actions: Create notes and attach relevant content to the contact record.
POST /contacts/:contactId/notes
Key fields: contactId, noteId, content
Faster implementation with no code, using pre-built endpoints in Zapier to automate common workflows.
Easier maintenance and updates; test workflows in minutes and deploy changes without developers.
Scalable automation across contacts, tasks, notes, and appointments with simple mappings.
This glossary covers API basics, endpoints, authentication, and data structures involved in connecting GHL Contacts API to Zapier App Connector.
Application Programming Interface: a defined set of rules that allow software components to communicate with each other.
A specific URL in an API that accesses a resource or collection of resources.
The process of verifying identity and permissions to access API resources.
The maximum number of API calls allowed within a defined time window, used to protect services from overload.
Automatically push new leads from your website or form into GHL Contacts as fresh contact records to kick off your automation.
Create or update tasks in your PM tool when GHL tasks are created or modified, ensuring teams stay aligned.
Automatically append notes to contacts when statuses shift, keeping history visible across apps.
Obtain client credentials and authorize the app in Zapier. Ensure the app has access to basic contacts data.
Select the Contacts API endpoints you need and map contact fields to your Zapier fields for seamless data flow.
Run tests in Zapier, verify triggers and actions, then deploy your workflow to run automatically.
No traditional coding is required. The Zapier App Connector provides a no-code interface to map fields, set up triggers, and perform actions against the GHL Contacts API. If you’re familiar with basic data fields, you can quickly assemble automation flows. For advanced scenarios, you can still customize field mappings and workflows through the app settings. Tip: Start with a simple read of a contact, then incrementally add tasks and notes to build a fuller automation stack.
For basic syncing, use core read endpoints such as GET /contacts/:contactId and GET /contacts/ to fetch contacts, along with GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to bring related data into your Zap. If you need write capabilities, you can use POST /contacts/ to create, and PUT /contacts/:contactId to update. Always test with a sample contact to validate mappings.
Zapier enforces encrypted connections (TLS) for data in transit and securely stores credentials. Use scoped permissions to limit access to only what your workflows require. Regularly rotate API keys or refresh OAuth tokens as part of your security routine. Monitor app activity for unusual access patterns.
Yes. You can create and update contacts and tasks via endpoints such as POST /contacts/ and POST /contacts/:contactId/tasks, and update with PUT. Note that some actions may require additional permissions set on your GHL account. Start with non-destructive tests to confirm behaviors before enabling automation in production.
Both OAuth 2.0 and API keys are supported depending on how your Zapier app is configured. OAuth provides user-consented access, while API keys can be used for service-to-service connections. Choose the method that best fits your security and deployment requirements, and ensure the selected method has the necessary read/write scopes.
Yes. API usage is subject to rate limits defined by your plan. If you anticipate heavy automation, consider batching requests, caching results where possible, and spacing trigger checks to stay within limits. Contact support if you need higher quotas or a tailored rate-limit strategy.
The Endpoint List is described in the Endpoints section of this guide. It enumerates core read/write operations and related resources such as contacts, tasks, notes, and business data. You can reference the full list there to plan which endpoints your workflows will call.
Due to high volume, we will be upgrading our server soon!
