Authenticate to the GHL Contacts API using OAuth 2.0 with the Zapier App Connector. The typical read scope is contacts.readonly, and to write or modify data you will request the contacts.write scope. Store tokens securely and refresh as needed.
In Zapier App Connector, create a connection named “Invoiced – Contacts API”, select the GHL Contacts API integration, and authorize via OAuth 2.0. Provide the client ID and secret from GHL, set the redirect URI, and request the appropriate scopes (including contacts.readonly and contacts.write as needed).
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
Trigger when a contact is updated in GHL to sync data into Zapier for downstream workflows.
Actions: Retrieve contact data, fetch related tasks and notes, and pull a contact list for reporting.
GET /contacts/:contactId
Key fields: contactId, name, email, phone, lastModified
Trigger: New note added or a tag is updated on a contact.
Actions: Create or update notes, add or remove tags, update contact metadata.
POST /contacts/:contactId/notes
Key fields: contactId, noteId, content, author
Trigger: New or updated tasks for a contact.
Actions: Create, update, or mark tasks as completed.
POST /contacts/:contactId/tasks
Key fields: contactId, taskId, title, dueDate, status
Faster setup with drag-and-drop connectors; no code required, cutting deployment time dramatically.
Synchronized data across GHL and connected apps ensures consistency and reduces manual entry.
Lower operating costs and improved accuracy through automated workflows and error reduction.
This glossary defines API, endpoint, webhook, OAuth 2.0, triggers, actions, and data mapping as used in this no-code integration.
A set of rules and endpoints that let you programmatically access GHL resources from APPNAME.
A specific URL path for a GHL API operation used by your integration.
An authorization framework that lets apps obtain access tokens securely without sharing passwords.
An event-driven HTTP callback used to notify apps when something changes in GHL.
Automatically create a GHL contact when a new lead enters APPNAME, then apply initial tags and assign to a campaign.
Sync contact status from GHL to APPNAME to trigger personalized campaigns based on lifecycle stage.
Create and track tasks in APPNAME from GHL activity to ensure follow-ups are completed automatically.
In APPNAME, choose the GHL Contacts API, authorize via OAuth 2.0, and approve the requested scopes.
Select triggers like contact updated, new note, or new task; map fields to Zapier fields and test.
Run tests, review data mappings, handle errors, and enable automation for production use.
To read contacts, grant the ‘contacts.readonly’ scope and use GET /contacts/:contactId to fetch a single contact. For multiple contacts, use GET /contacts/. Ensure your OAuth token includes the correct scope. Practical reads can be combined with related endpoints like GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to assemble a full profile.
Yes, you can write or update contacts using endpoints such as POST /contacts/ to create and PUT /contacts/:contactId to update. Deleting is available via DELETE /contacts/:contactId. Your token must have the ‘contacts.write’ scope for these operations. Use caution and validate data mappings to avoid unintended changes. In Zapier, implement safeguards like filters and confirmations where appropriate.
OAuth 2.0 tokens expire and must be refreshed. The APPNAME integration should use the refresh token flow to obtain a new access token without requiring the user to re-authenticate. Monitor token expiry and set up automatic refresh in your app configuration.
Notes and tasks are manipulated through POST and PUT endpoints such as POST /contacts/:contactId/notes and POST /contacts/:contactId/tasks. These endpoints support creating new items or updating existing ones. Use appropriate triggers in Zapier to respond to changes in notes or tasks and keep data in sync across apps.
No coding is required to set up the integration in a no-code environment like Zapier App Connector. You will configure a connection, define triggers and actions, and map fields between GHL and APPNAME. If you need more complex logic, you can layer filters, paths, and multi-step workflows within Zapier.
Yes, there are rate limits on the GHL API. Plan your calls, batch requests when possible, and implement retry logic with exponential backoff to handle transient errors gracefully.
The API endpoint list is documented in the integration guide. You can reference the ENDPOINTLIST token in your content and consult the GHL API docs for additional endpoints and usage notes.
Due to high volume, we will be upgrading our server soon!
