Authenticate to the GHL Contacts API using OAuth credentials or an API key, ensuring the scope includes contacts.readonly for read access. Keep tokens secure and rotate them regularly.
In Zapier, connect the Zapier App Connector to your GHL account by selecting the Contacts API integration and granting the necessary permissions. A secure session will be established for the duration of your automations.

Fast setup with intuitive UI, zero coding required
Automate data sync across contacts, notes, tasks without writing code
Reusable templates for repeatable processes and scalable workflows
Key elements include endpoints, authentication, triggers, actions, and data mapping between GHL Contacts API and Zapier App Connector
Application Programming Interface: a set of endpoints that let apps talk to each other and exchange data
Security process to verify identity and grant access to resources
A specific route in an API that performs an action or returns data
A URL that receives event payloads from another service (not used in this read-only example)
When a new contact is added in GHL, automatically create a welcome task and a notes template in Zapier to immediately engage the new lead.
Trigger tasks when contact status changes in GHL and route updates to your project management tool via Zapier.
Push full contact profiles, including notes and tasks, to a data warehouse or CRM for analytics and reporting.
Connect your GHL account for the Contacts API and grant Zapier App Connector the necessary scopes
Choose endpoints such as /contacts/:contactId and /contacts/:contactId/tasks to populate your Zapier workflows
Create Zaps, simulate runs, and monitor results in the Zapier dashboard
The GHL Contacts API exposes endpoints to read and manage contact records, tasks, notes, and more. In Zapier, you can connect and orchestrate these endpoints to automate CRMs and workflows without writing code. By using the Read-Only scope, you can safely fetch data for reporting and automation triggers. For more advanced workflows, you may request elevated permissions through your GHL administrator to enable additional write actions as needed.
No full‑stack coding is required. Zapier App Connector provides a visual builder to connect endpoints, map fields, and configure triggers and actions. Some basic understanding of your data structure helps you design effective automations, but minimal to no coding is often sufficient. If you need complex transformations, you can add small code steps within Zapier or pre-process data in a prior step.
Core endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, POST /contacts/, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, and more. These allow you to read, create, and update key CRM data. Your exact needs determine which endpoints you should map; start with basic read endpoints and expand as your automations mature.
Permissions are defined by your GHL access and the scope granted to Zapier. Read access (contacts.readonly) allows viewing data, while write endpoints require appropriate authorization. Always adhere to least privilege and rotate credentials regularly. Regularly audit your connected apps to ensure that only approved automations have access to sensitive data.
Security is maintained through OAuth tokens or API keys, encrypted transmission, and scoped access. Zapier stores connection data securely, and you control which Zaps have access to your GHL data. For additional protection, enable IP whitelisting and monitor token activity in your GHL and Zapier accounts.
Yes. You can map fields such as contactId, name, email, and custom fields between GHL and Zapier. The App Connector provides field mapping in both triggers and actions, so you can format data for downstream systems or dashboards. If a field is missing, you can create a custom field in GHL or use a data transform step in Zapier.
Common issues include invalid credentials, insufficient scopes, or endpoint mismatch. First, re-authenticate the connection and verify the scope. Next, confirm the endpoint paths and ensure you are using the correct environment (sandbox vs. production). If issues persist, check API rate limits and review any recent changes to your GHL configuration or Zapier app connector settings.
Due to high volume, we will be upgrading our server soon!
