Access the Contacts API from Zapier by using your GHL credentials and sending an Authorization header with a Bearer token. Start with your API key and the required scope (contacts.readonly for view-only access; use contacts.write for changes).
In Zapier, create a new connection to the Contacts API by providing your GHL API credentials. Select the appropriate authentication method and grant the needed scopes for your workflow.

Centralize analytics and segmentation from Zapier workflows
Key elements include authentication, endpoints, triggers, actions, and data fields used by the Zapier–Contacts API integration.
API stands for Application Programming Interface: a set of rules that lets different software talk to each other.
OAuth 2.0 is an authorization framework that lets apps access data securely without sharing passwords.
An Endpoint is a specific URL in an API that performs a function and returns data.
Rate limit is the maximum number of API requests allowed in a given period, used to prevent abuse.
Capture website form submissions and automatically create or update contact records in the Contacts API via Zapier.
Automatically tag contacts and create related tasks when activity occurs in connected apps.
Set up follow-up reminders after form submissions or task completions.
In Zapier, select Contacts API as the app, then choose authentication and connect your GHL account.
Choose a trigger such as New Contact or Updated Contact and map fields to your Zapier action.
Define actions like Create or Update a contact, attach notes, or create tasks.
You’ll need a GHL API key and a Zapier connection. Provide the key in the Authorization header and ensure your connection has the required scope for your task. If you run into permissions issues, verify that the endpoint supports the chosen scope and consult the API docs for roles.
Yes. Using the contacts.readonly scope allows you to fetch data without making changes. If you need to modify data, switch to contacts.write and ensure secure handling of credentials.
The integration exposes endpoints for retrieving contacts, tasks, notes, and appointments, plus create/update/delete actions. Typical calls include GET /contacts/:contactId, POST /contacts/ to create, and PUT/DELETE for updates or removals.
The API enforces a rate limit to prevent abuse. Plan your workflows accordingly and implement retries with exponential backoff for transient errors. For large data syncs, batch processing is recommended.
Yes. You can create, update, and delete contacts from Zapier, and you can attach related tasks and notes in the same workflow. Map fields carefully and test your Zap in a sandbox before going live.
Use Zapier’s built-in test features to pull sample data and send test requests to the Contacts API. Check the response payload and authentication headers, then iterate on field mappings and error handling.
The endpoint list and field mappings are provided in the Endpoints section of this guide and within the Zapier app documentation. When configuring a Zap, review available fields and their data types to ensure proper mapping.
Due to high volume, we will be upgrading our server soon!
