Authenticate requests to the Contacts API using OAuth 2.0, then pass the access token in the Authorization header. Use the same credentials you use for your GHL account.
Connect your Zapier app securely, authorize with your GHL account, and manage scopes to control what the integration can access.
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; 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: new or updated contact in GHL initiates a Zap in Zapier
Actions: upsert contact in GHL via PUT /contacts/:contactId, optionally attach notes or tasks
PUT /contacts/:contactId
email, name, phone
Trigger: when a contact’s tasks are created or updated
Actions: list tasks, create new task, update task status
POST /contacts/:contactId/tasks
taskId, title, dueDate
Trigger: a note is added or updated for a contact
Actions: create note, fetch notes, update note
POST /contacts/:contactId/notes
notesId, content
Rapid integration without custom code between GHL and Zapier
Automate multi-step workflows across apps in minutes
Scale data flows with error handling and retries
A concise glossary of terms and the core data flow for connecting the GHL Contacts API via the Zapier App Connector.
An API is a set of rules that allows apps to communicate, fetch data, and trigger actions programmatically.
A specific URL and HTTP method used to access a resource in an API.
The process to verify identity and authorize access, commonly via OAuth 2.0 or API keys.
A way for an app to receive real-time notifications when an event occurs.
Set up a workflow that creates or updates a contact when a new lead is captured, assigning tasks and notes automatically.
Trigger reminders when tasks approach due dates and notify teammates via Zapier actions.
Automatically summarize new notes and push summaries to a shared channel.
Create a connected app in GHL and grant OAuth permissions to Zapier App Connector.
Use sample API calls to verify data flow and mapping.
Create Zaps to automate actions based on triggers.
No coding is required: use Zapier to connect GHL and the Contacts API through a visual workflow builder. You can map fields, set up triggers, and configure actions without writing code. The platform handles data transfer and error handling for you. Tip: start with a simple trigger and expand as you grow.
Authenticate using OAuth 2.0 and provide the necessary tokens in requests. In GHL, create a connected app and authorize Zapier App Connector. In Zapier, link the GHL-connected app to your workflow and select the required scopes. Security note: keep tokens secure and refresh as needed.
EndPoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes, and more. Check the Endpoint List for the full set and rate limits. If a specific endpoint isn’t listed, you can typically use a related endpoint with the same auth and payload shape.
Implement retry logic with exponential backoff, handle 429 Too Many Requests, and respect rate limits defined by your GHL plan. Use Zapier’s built-in scheduling and error handling features to pause and retry as needed.
Rate limits vary by endpoint and plan. Plan for bursts and implement a backoff strategy in your Zapier workflows to stay within allowed limits. Monitor usage with dashboards and alerts.
Use secure storage for tokens, rotate credentials regularly, and only request the minimum scopes necessary for your automation. Follow best practices for API security and webhook validation.
In Zapier, use test mode and sample data to validate your Zap steps before enabling live runs. Use the built-in test feature to verify mapping and data flow.
Due to high volume, we will be upgrading our server soon!
