To securely access the Contacts API, obtain an OAuth 2.0 access token with the required scope (contacts.readonly) and include it in the Authorization header of each request. Rotate tokens regularly and store them securely.
In Zapier, connect to GHL using a secure connected account. Use OAuth or an API key as supported, and let Zapier manage token refresh automatically.
Endpoints covered in this guide 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, 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. These endpoints let you fetch, create, update, and manage contacts, tasks, notes, tags, and appointments.
Trigger: when a contact is updated in GHL; fetch details with GET /contacts/:contactId to sync with APPNAME.
Actions: create or update contact in APPNAME, attach notes and tags as needed.
GET /contacts/:contactId
contactId, name, email, phone, tags, lastUpdated
Trigger: new or updated tasks appear under a contact; view via GET /contacts/:contactId/tasks.
Actions: create/update tasks in APPNAME; set completed status via PUT /contacts/:contactId/tasks/:taskId/completed.
GET /contacts/:contactId/tasks
contactId, taskId, title, status, dueDate
Trigger: new notes or appointments for a contact; pull data with GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments.
Actions: push notes to APPNAME using POST /contacts/:contactId/notes and sync appointments as needed.
GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments
contactId, noteId, appointmentId, date, summary
No-code automation lets you build powerful data flows without writing code, using Zapier triggers and actions against the GHL API.
Real-time syncing between GHL and your apps ensures up-to-date contact data and timely task completion.
Consolidated records and activity history reduce manual data entry and errors.
Key elements include endpoints, authentication, triggers, actions, and data fields. Understanding these helps you design reliable automations.
A specific URL path used to perform an operation against the GHL Contacts API (e.g., GET /contacts/:contactId).
A token issued after authentication that authorizes API requests.
A person in GHL with associated data like name, email, phone, and activity history.
A URL endpoint that receives real-time notifications when events occur in GHL.
Capture new leads in APPNAME and push them to GHL via POST /contacts/ to automatically create or update contacts.
When notes are added in APPNAME, mirror them in GHL via POST /contacts/:contactId/notes to keep history.
Create and update tasks in GHL from APPNAME project milestones using POST/PUT on /contacts/:contactId/tasks.
Configure OAuth with GHL and connect the account in Zapier’s App Connector.
Select endpoints such as notes, tasks, and contacts; map fields and set test data.
Run tests, verify data flow, and turn on the Zap for live automation.
No coding is required. You can connect GHL to Zapier using a secure connected account. Define triggers and actions in a no-code Zap to automate workflows. You control which data flows between GHL and APPNAME.
Commonly used endpoints include GET /contacts/:contactId to fetch data, GET /contacts/:contactId/tasks to retrieve tasks, and POST /contacts/ to create new contacts. For notes and appointments, prefer GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments. Map fields to fit your automation goals.
Use OAuth tokens and API keys securely. Store credentials in the connected account area of Zapier, rotate tokens regularly, and never expose tokens in logs. Enable least-privilege access with the contacts.readonly scope when appropriate.
Yes. You can update existing GHL contacts with PUT /contacts/:contactId and reflect those changes back into APPNAME as needed. Use mapping to ensure name, email, and other fields stay in sync.
Rate limits vary by plan. Monitor your usage, implement retry with exponential backoff, and batch requests when possible to stay within quotas.
Test using Zapier’s built-in test tools and a sample contact. Validate field mappings, triggers, and actions, then review task logs and data flow before going live.
The API docs provide a complete endpoint list and their purposes, including endpoints for contacts, tasks, notes, and appointments. Use GET examples to explore data structures and required parameters.
Due to high volume, we will be upgrading our server soon!
