Use OAuth 2.0 or API tokens provided by the GHL developer console to securely authenticate API calls to the Contacts API. Ensure scopes include read and write as needed.
In Zapier, configure a connected app with client ID and client secret; securely store credentials and enable token refresh to keep connections alive.
GET /contacts/:contactId — Retrieve a contact by ID; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task; GET /contacts/:contactId/notes — List notes for a contact; GET /contacts/:contactId/notes/:id — Retrieve a specific note; GET /contacts/:contactId/appointments — List appointments for a contact; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List contacts for a business; contacts.write — Permission to write to contacts; POST /contacts/ — Create a new contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task complete; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact
Trigger on new or updated contacts in GHL and push data to Zapier to power a workflow.
Actions include creating or updating a contact in GHL from Zapier, adding notes, or creating related tasks.
Example methods: POST /contacts/ to create and PUT /contacts/:contactId to update; use POST /contacts/:contactId/tasks to create tasks.
Key fields: contactId, email, name.
Trigger on new notes or tasks added to keep information aligned across systems.
Actions include cloning notes to GHL and creating tasks in GHL from APPNAME events.
Use POST /contacts/:contactId/notes and POST /contacts/:contactId/tasks for creation; PUT endpoints for updates.
Key fields: contactId, noteId, taskId
Trigger when invoicing data changes in Fatture in Cloud related to a contact and sync highlights to GHL.
Actions include updating custom fields, tagging, or creating related tasks in GHL from invoice data.
POST /contacts/:contactId, PUT /contacts/:contactId, and POST /contacts/:contactId/tags depending on the workflow.
Key fields: contactId, invoiceId, customerEmail
Automate data flows without writing code.
Fast setup with pre-built endpoints and triggers in Zapier App Connector.
Reduce manual data entry and ensure consistency across systems.
This glossary covers API basics, authentication, triggers, actions, endpoints and data fields used to connect GHL Contacts API with APPNAME.
Application Programming Interface: a set of rules that enables software to communicate.
OAuth 2.0 authorization framework for secure access tokens.
A specific URL in an API that performs an action or returns data.
A real-time notification mechanism that fires when data changes.
Trigger a reminder when a contact’s invoice status changes in Fatture in Cloud; create a follow-up task in GHL.
Sync invoice notes to contact notes in GHL for a complete history.
Auto-tag customers by billing value or payment status to tailor campaigns.
Create the connected app, authorize, and validate permissions in both GHL and APPNAME.
Choose endpoints and map fields, then set up triggers and actions in Zapier.
Test end-to-end flows, verify data mapping, and deploy to production.
No-code integration is possible with the Zapier App Connector. Start by creating a connected app in GHL, authorize the connection, and choose triggers like New or Updated Contacts. Then map fields and set actions to create or update contacts in GHL from APPNAME. If you encounter permission errors, verify that the correct scopes (such as contacts.readonly and contacts.write) are granted and that the access token is valid and refreshed automatically.
Essential endpoints include GET /contacts/:contactId to retrieve contact data, POST /contacts/ to create, PUT /contacts/:contactId to update, and POST /contacts/:contactId/tasks to manage tasks. For notes and appointments, GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments are commonly used. Use these in workflows that require syncing or enriching contact records.
Secure authentication uses OAuth 2.0 tokens or API keys issued by GHL. Store credentials securely in Zapier, enable token refresh, and rotate credentials periodically. Always limit token scope to what your workflow requires and monitor access logs for unusual activity.
Yes. You can synchronize notes and tasks automatically by triggering on note or task changes and performing corresponding actions in the other system. This keeps contact history and to-dos aligned across GHL and APPNAME without manual data entry.
Rate limits depend on your GHL plan. Implement exponential backoff and retry logic in Zapier to handle transient errors. If limits are reached, stagger requests and batch operations where possible to avoid hitting caps.
Enable detailed logging for triggers and actions, review request payloads, and use test mode in Zapier to reproduce failures. Validate field mappings, endpoint availability, and authorization status to identify root causes quickly.
Due to high volume, we will be upgrading our server soon!
