Authenticate requests to the Contacts API by obtaining a valid access token with the required scope (contacts.readonly). Store credentials securely and rotate tokens as needed.
In Zapier, connect the Zapier App Connector to your GHL account using OAuth 2.0. Grant the appropriate scopes to read and/or write data, depending on the endpoints you plan to use.
Key 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; API endpoint: 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
Trigger: when a new contact is created in GHL, or an existing contact is updated, to push data into Zapier workflows.
Actions: create or update a contact in GHL from Zapier; pass core fields like name, email, and phone; optionally create tasks or notes.
POST /contacts/ to create or PUT /contacts/:contactId to update existing contacts.
Required fields: name and email; phone is optional; additional fields include company and title.
Trigger: a new task is created for a contact in GHL, which starts a Zapier workflow.
Actions: create, update, or complete tasks via endpoints like POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId.
POST /contacts/:contactId/tasks
Required fields: title; optional: dueDate, description, priority, assignee
Trigger: a note is added or a tag is updated on a contact in GHL.
Actions: post notes with POST /contacts/:contactId/notes and add tags with POST /contacts/:contactId/tags.
POST /contacts/:contactId/notes; POST /contacts/:contactId/tags
Required fields: contactId; for notes: content; for tags: tag name
Automate repetitive data entry between GHL and other apps without writing code
Enable real-time syncing of contacts, tasks, notes, and tags across your stack
Build auditable, scalable workflows with history and error handling
This glossary covers API endpoints, authentication, triggers, actions, and field mappings used to connect the GHL Contacts API with the Zapier App Connector.
A set of rules that defines how software components communicate with the GHL Contacts API via HTTP.
The process of granting access to apps via OAuth 2.0 and access tokens.
A specific URL in the API used to perform an action, such as retrieving or updating a contact.
A short-lived credential used to authorize requests to the API after authentication.
Capture new form leads from your site and automatically create contacts in GHL via Zapier.
When a GHL task is updated, push a notification to your project management tool via Zapier.
Automatically add tags to contacts based on activity to trigger targeted campaigns.
Authorize the Zapier App Connector to access your GHL account and select the Contacts API.
Select a trigger like ‘New Contact’ and an action like ‘Create Task’ to automate workflows.
Run a test to verify data flow and deploy your Zap once it passes.
You generally need read permissions for most flows. For creating or updating data, request write access and ensure the defined scopes match the endpoints you plan to use. In Zapier, authenticate once and reuse the connection across Zaps.
No coding is required for basic automations. Zapier provides a visual editor to set triggers and actions. For advanced mappings, you may need to use custom fields or code by Zapier.
Common endpoints include GET /contacts/:contactId and POST /contacts/ for managing contacts, as well as task and note endpoints. Field mapping is done in Zapier via the built-in UI.
OAuth 2.0 is used to grant Zapier access to GHL. You’ll be prompted to log in and authorize; after that, Zapier stores a token and refreshes it automatically.
You can update existing contacts using PUT /contacts/:contactId and manage tasks with PUT /contacts/:contactId/tasks/:taskId.
Rate limits depend on your GHL plan and token scopes. If you exceed limits, retries with backoff are recommended.
Map fields by using Zapier’s built-in mappings and data types. Always test the mapping to ensure data integrity.
Due to high volume, we will be upgrading our server soon!
