Authenticate GHL API calls using OAuth 2.0 with the required scope: contacts.readonly to protect data while enabling automation.
In APPNAME’s Zapier integration, configure a GHL connection by selecting OAuth 2.0, entering client credentials, and granting the contacts.readonly scope. Store tokens securely and rotate as needed.
Available endpoints include: 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, 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. Permissions include: contacts.write.
Trigger: when a contact is created or updated in GHL, syncs to APPNAME.
Actions: create or update the contact in APPNAME, and optionally attach related notes or tasks.
GET /contacts/:contactId
contactId, lastModified
Trigger: a new or updated task in GHL should create or update a corresponding task in APPNAME.
Actions: sync tasks and status between GHL and APPNAME; create, update, or complete tasks as needed.
GET /contacts/:contactId/tasks
contactId, taskId, status
Trigger: notes added or updated in GHL should reflect in APPNAME.
Actions: log notes in APPNAME and associate with the related contact; optionally create reminders.
GET /contacts/:contactId/notes
contactId, noteId
Faster setup with no-code automation using Zapier App Connector.
Easier maintenance through centralized zaps and automatic updates.
Reliable data sync across contacts, tasks, notes, and appointments with built-in error handling.
This glossary covers endpoints, authentication, data mapping, triggers, actions, and error handling to help you build reliable automations.
A specific URL path and HTTP method used to access a resource in the GHL API.
Authorization framework that lets apps obtain access tokens after user consent.
Permissions that define what data an app can read or write.
A callback mechanism that notifies your app of events in real-time.
Automatically tag contacts in APPNAME based on activity and properties pulled from GHL for smarter segmentation.
Route tasks to the right owner in APPNAME using contact insights from GHL.
Create follow-up reminders and calendar events in APPNAME when GHL appointments are scheduled.
Generate a client secret or API access and configure OAuth 2.0 for APPNAME.
In Zapier, authorize the GHL connection and grant the required scopes.
Create Zaps that map GHL data to APPNAME fields for contacts, tasks, and notes.
No developer account is required to get started with Zapier App Connector. You will need access to both GHL and APPNAME, and you can authenticate via OAuth 2.0. If you already have a GHL workspace, you can generate credentials in the GHL developer settings. In Zapier, connect APPNAME to GHL and choose the Contacts API with the required scope.
Use OAuth 2.0 for secure access and token rotation. For read-only automation, apply the scope: contacts.readonly. If you need write access, request the appropriate scope like contacts.write, and ensure your app handles updates safely.
Key endpoints for syncing contacts include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments. Map the results to corresponding APPNAME fields and handle pagination as needed.
Yes. You can create Zaps that trigger on GHL events (e.g., new task, new note) and push updates to APPNAME automatically. Use filters and mappings to control what gets synced and when.
Implement retries with exponential backoff and provide clear error messages. Use Zapier’s built-in retry logic and consider queueing failures to reprocess later.
Yes, API rate limits apply. Plan your polling frequency and pagination strategies to stay within quotas, and leverage webhooks where available to reduce polling.
The API endpoint list is in the GHL developer docs for the Contacts API. In this guide, we summarize the most commonly used endpoints and show how to map them to APPNAME fields.
Due to high volume, we will be upgrading our server soon!
