Use a secure token or OAuth flow to authorize API requests. Ensure scopes are set to readonly for data retrieval or full access for write operations
Zapier handles app authentication via OAuth2 or API keys depending on your setup; configure credentials in your connector settings
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, API Endpoint9: contacts.write, API Endpoint10: POST /contacts/, API Endpoint11: PUT /contacts/:contactId, API Endpoint12: DELETE /contacts/:contactId, API Endpoint13: POST /contacts/:contactId/tasks, API Endpoint14: PUT /contacts/:contactId/tasks/:taskId, API Endpoint15: PUT /contacts/:contactId/tasks/:taskId/completed, API Endpoint16: DELETE /contacts/:contactId/tasks/:taskId, API Endpoint17: POST /contacts/:contactId/tags
Trigger: A new contact is added in your source system then upsert the contact in the Contacts API via POST /contacts
Actions: Upsert contact data including name email phone and company; optionally create initial tasks or notes
POST /contacts/
Required fields: name email; Optional: phone, company, custom fields
Trigger: A contact is updated and you need latest data synced to the app
Actions: Read contact details via GET /contacts/:contactId and pull related tasks notes and appointments
GET /contacts/:contactId
Key fields: contactId name email
Trigger: New task or note created for a contact or status change
Actions: Create update or delete tasks with POST /contacts/:contactId/tasks PUT /contacts/:contactId/tasks/:taskId and manage completion with PUT /contacts/:contactId/tasks/:taskId/completed; fetch or add notes with GET /contacts/:contactId/notes
POST /contacts/:contactId/tasks and related task endpoints plus notes retrieval
Fields: contactId taskId title status
Automate repetitive workflows without writing code
Achieve real time data sync across systems
Scale processes easily with a centralized integration
This section defines essential terms and core processes involved in connecting the Contacts API to the Zapier App Connector including endpoints authentication triggers and actions
Authentication methods used by the API such as OAuth 2.0 Bearer tokens
A specific API route such as /contacts and /contacts/:contactId
An event in one app that starts an automation in another app
A method for real time data push from one app to another
Automatically create contacts in GHL when a lead is added in a CRM and kick off onboarding tasks
Sync notes and tasks from support tickets into GHL to keep all data in one place
Trigger renewal reminders when contact status changes and create follow up tasks automatically
Obtain API key or OAuth credentials for Contacts API and configure in the Zapier app
Add required endpoints map fields and test the connection
Create a Zap that triggers on a contact event and performs actions like creating tasks
You can authenticate using OAuth 2.0 or API keys depending on how your app is configured. Ensure the access token has the proper scopes for reading or writing data. If you are using a key based approach, keep credentials secure and rotate them regularly.
The Contacts API exposes endpoints for retrieving and manipulating contacts tasks notes appointments and tags. You can list get create update and delete contacts and manage related resources like tasks and notes. Use GET POST PUT and DELETE as appropriate for each resource.
Yes you can update a contact via PUT /contacts/:contactId. You can also update tasks via PUT /contacts/:contactId/tasks/:taskId and mark them completed with PUT /contacts/:contactId/tasks/:taskId/completed. Make sure your Zapier actions map the correct IDs.
Rate limits depend on your GHL account and API plan. Implement retry logic and exponential backoff in your Zapier workflows. If you approach the limit you can queue requests or stagger runs to stay within quotas.
No code is required to start, as Zapier App Connector provides a no code interface to connect endpoints and map fields. Basic configuration includes authentication credentials endpoint paths and simple field mappings.
To test the connection use the built in test feature in Zapier to validate a sample run. Confirm you can fetch a contact or create a new one and verify the data mirrors in GHL. Review error messages to adjust scopes and endpoints as needed.
Starting the sync will not erase existing data by default. It will pull and push data based on the triggers and actions you configure. You can implement safeguards to avoid duplicates and reconcile conflicts as part of your Zap design.
Due to high volume, we will be upgrading our server soon!
