Use OAuth 2.0 Bearer tokens with the Contacts API and the required scope: contacts.readonly. Include your access token in the Authorization header.
Zapier handles authentication for the connected GHL app; connect the Zapier App Connector to your GHL account and grant access to the Contacts API.

Automate repetitive tasks without writing code.
Fast data synchronization between GHL and Leadpages.
Scalable, repeatable workflows with centralized logs and audit trails.
Overview of elements and processes used to connect GHL Contacts API with Zapier App Connector.
A set of rules that allow software applications to communicate with each other and share data.
The process of proving identity and authorizing API requests.
A specific URL path in an API that performs an action.
A callback URL that receives real-time notifications from another app.
Automatically add new GHL contacts to Leadpages lists via Zapier.
Send task due dates from GHL to Leadpages to trigger reminders.
Keep notes synchronized between Leadpages and GHL for full context.
Connect your GHL account and authorize access to the Contacts API; then connect the Zapier App Connector.
Choose a GHL trigger and a Leadpages action, then map fields.
Run tests, enable the Zap, and monitor results.
No coding is required. Use Zapier App Connector’s visual editor to connect GHL’s Contacts API to Leadpages actions. Start by selecting a trigger, then map fields from the GHL contact to Leadpages, save your Zap, and run a test. The workflow can be adjusted as your Leadpages campaigns evolve.
You will typically use a combination of GET endpoints to read data and POST/PUT endpoints to create or update records. For Leadpages integration, focus on creating or updating contacts (POST /contacts/, PUT /contacts/:contactId) and syncing notes or tasks (POST/PUT for notes and tasks).
Yes. You can read contact data with GET endpoints and write changes back with POST, PUT, or DELETE as permitted by your scopes. Ensure you have the correct permissions configured in GHL and in Zapier.
Security is maintained through OAuth tokens, encrypted data transmission, and least-privilege access. Only the required scopes (eg, contacts.readonly) should be granted for your workflow.
Yes. You can filter and route by tags by mapping tag fields in Zapier and applying tag-based filters within your Zap steps to control which contacts are affected.
If a Zap fails, review the task history in Zapier, verify OAuth scopes, and test each step individually. Check endpoint responses for error codes and adjust mapping or data formats as needed.
Logs appear in Zapier task history and, where configured, in GHL’s audit logs. Use these to track data flow, field mappings, and any failed requests.
Due to high volume, we will be upgrading our server soon!
