Authenticate requests to the Contacts API using your GHL credentials with the required scope: contacts.readonly. Use OAuth2 tokens or API keys as configured in your GHL developer settings.
In Zapier, create a connection to the GHL Contacts API by providing your app credentials. Store tokens securely and rotate them per your security policy.
Available 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; 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 contact is updated in GHL, fetch the latest contact details and related tasks to start a Zap.
Actions: Retrieve tasks (GET /contacts/:contactId/tasks), fetch notes (GET /contacts/:contactId/notes), and create or update tasks (POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId).
GET /contacts/:contactId
Key fields: contactId; optional: taskId for task drilling. Map fields such as name, email, and status.
Trigger: when a note is added or updated on a contact, start a Zap to sync or archive notes.
Actions: Read notes (GET /contacts/:contactId/notes) and retrieve specific note details (GET /contacts/:contactId/notes/:id).
GET /contacts/:contactId/notes
Key fields: contactId, id
Trigger: when a task is updated or an appointment is created for a contact, start a Zap.
Actions: Update tasks (PUT /contacts/:contactId/tasks/:taskId), mark complete (PUT /contacts/:contactId/tasks/:taskId/completed), and read appointments (GET /contacts/:contactId/appointments).
GET /contacts/:contactId/tasks
Key fields: contactId, taskId, appointmentId
Build powerful automations without writing code by linking data between GHL and your other apps in Zapier.
Use drag and drop to map fields, set up triggers and actions, and test flows instantly.
Centralized CRM data across systems reduces duplicate work and errors.
This glossary defines API endpoints, authentication, triggers, actions, and data mapping used in the GHL Contacts API Zapier integration.
A specific URL and HTTP method that allows your app to request data from GHL.
A to-do item linked to a contact used to manage follow-ups.
A person stored in GHL with attributes like name, email, and notes.
A freeform item attached to a contact to capture context or history.
When a new contact signs up, automatically create a corresponding task in GHL to follow up.
Push form submissions into the contact notes to keep complete activity history.
When a purchase completes, automatically update contact fields such as status or loyalty tier.
Create or select your GHL API credentials and connect to Zapier App Connector, ensuring the scope matches contacts.readonly.
Pick the endpoints you need and map fields in Zapier.
Run tests, confirm data flows, and deploy your automation.
The Contacts API is GHL’s RESTful interface that lets apps read and manage contact records, tasks, notes, and related data. It provides endpoints for retrieving information and performing updates. In this integration you can use endpoints like GET /contacts/:contactId and GET /contacts/:contactId/tasks to surface CRM data in Zapier workflows, enabling automation without coding.
Authentication is handled via GHL API credentials and the access token with the required scope, such as readonly. In this setup, ensure your Zapier connection uses the same credentials and scopes and rotates tokens securely.
The available endpoints include read operations such as GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and others, plus write operations such as POST /contacts/ and PUT /contacts/:contactId. Use the endpoints that fit your use case and map fields accordingly; some endpoints require contactId, others require taskId or note id.
Yes. Zapier provides a no-code interface to connect GHL and your apps by creating Zaps that trigger on events and perform actions. This means you can automate CRM workflows without writing code.
Rate limits apply to GHL API requests; if you hit limits, implement exponential backoff and staggered requests. Plan your Zaps to batch updates where possible and cache data to minimize unnecessary calls.
When errors occur, Zapier surfaces error messages. Use built-in retry rules and test steps to identify whether the problem is authentication, permissions, or endpoint issues. Always check scope, endpoint path accuracy, and data mapping; enable detailed logging and retries during testing the workflow.
Yes, no-code automation is possible using the Zapier App Connector to connect GHL’s Contacts API. You can build complex workflows with triggers, actions, and conditional logic without writing code.
Due to high volume, we will be upgrading our server soon!
