To access the Contacts API you authenticate with your GHL credentials using the required scope of contacts.readonly. Use a secure method such as an OAuth token or API key as supported.
Authorize the Zapier App Connector with your GHL account, store credentials securely, and refresh tokens as needed.

Automate Mercado Pago notifications without writing code
Real time data sync between your Contacts API and automation workflows
Use prebuilt triggers and actions to speed up setup
This glossary defines core elements and processes used in connecting the GHL Contacts API with the Zapier App Connector
A person in the Contacts API with a dedicated record in your system
A unit of work linked to a contact such as follow ups or reminders
A text entry attached to a contact for context
A specific API route used to perform actions or fetch data
Set up a Zap that creates or updates a contact whenever a Mercado Pago event occurs, keeping contact data fresh.
When a task is created in Contacts API, mirror it to your task management tool for real time collaboration.
Attach notes from contact records to customer journeys for richer context in automation.
Connect your GHL account and the Zapier App Connector to begin integrations.
Select the relevant endpoints (eg contacts tasks notes) and map triggers to actions in your workflow.
Run tests, verify data flow, and deploy your automation with confidence.
The Contacts API is a RESTful interface that lets you access and manage contact data within GHL. Use the endpoints to pull or update contacts, tasks, notes, and more. This page focuses on Mercado Pago notifications and how to connect via the Zapier App Connector. In addition, start with authentication steps and test endpoints in a sandbox to avoid impacting live data.
Authentication is typically done via OAuth tokens or API keys with proper scopes. For the App Connector, secure credential storage and token refresh are essential. In the Zapier setup, connect accounts and grant permissions as prompted. Use the test feature to confirm access before routing live events.
Notifications endpoints include contacts/:contactId and related resources. You can pull and monitor tasks, notes, and appointments to trigger downstream actions. Always respect rate limits and refer to your API docs for the exact response schemas.
Yes. Use a sandbox environment or mock data to safely run tests without touching real records. Validate each step of the workflow before moving to staging or production.
No extensive coding is required. The App Connector provides no code triggers, actions, and filters to map to your workflows. If custom transformations are needed, lightweight logic can help.
API endpoints are listed in the page content and here. You will typically access them via GET, POST, PUT, and DELETE operations to manage contacts, tasks, notes, and more. Bookmark the docs for quick reference during setup.
If you encounter authentication failures or missing endpoints, re-check credentials, scopes, and permissions. Review rate limits and implement retry logic; contact support if issues persist.
Due to high volume, we will be upgrading our server soon!
