Authenticate requests to the GHL Contacts API using your API credentials and the chosen auth flow. Make sure the selected scope aligns with your use case (for example, contacts.readonly for read access).
Configure OAuth 2.0 or an API key-based approach in the Zapier App Connector to securely call the GHL API and protect your data.
Key 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; 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
Action: Create or Update Contact in the Zapier App
PUT /contacts/:contactId
id, email, name
Trigger: New Task for a Contact in GHL
Action: Create Task in the Zapier App
POST /contacts/:contactId/tasks
contactId, taskId, title
Trigger: New Note for a Contact in GHL
Action: Create Note in the Zapier App
GET /contacts/:contactId/notes
contactId, id
Automate repetitive tasks without writing code, saving time and reducing manual data entry.
Instant data syncing between GHL and your apps for up-to-date contact activity.
Scalable workflows with reusable templates and triggers.
A quick glossary of terms you’ll encounter when integrating GHL’s Contacts API with the Zapier App Connector, including endpoints, authentication, triggers, and data mapping.
A specific URL path and HTTP method used to perform an action against the GHL API.
A method to verify requests and grant access to resources (OAuth2, API keys).
An event in GHL that starts a Zap in Zapier (e.g., new contact).
The process of aligning fields between GHL and the Zapier app to ensure correct data flow.
When a lead enters your CRM, automatically create a corresponding GHL contact via the API and begin onboarding tasks.
Create tasks in GHL when a new deal reaches a stage in your pipeline, keeping teams aligned.
Aggregate notes from multiple sources for a complete contact activity history.
Obtain your GHL API credentials and set up OAuth or API key authentication in Zapier.
Select the endpoints you’ll use (e.g., get contact, list notes) and map fields to your Zapier app.
Test the connection end-to-end and deploy your workflow to production.
No coding is required thanks to the Zapier App Connector. Use the prebuilt GHL integration templates to connect your Contacts API with your workflows. You can trigger actions, map fields, and automate data flows without writing any code. If you do customize, you’ll typically modify field mappings and test endpoints within the connector UI.
For a basic sync, focus on essential endpoints like GET /contacts/:contactId, GET /contacts/:contactId/notes, and POST /contacts/ for creation. Map key fields (id, email, name) to your app, and set up triggers such as New Contact or New Note to start your automation.
Authenticate with GHL by using your API credentials and the supported flow (OAuth2 or API Key). In Zapier App Connector, configure the same credentials and scopes, then test calls to ensure authenticated access to the Contacts API. Use secure storage for tokens and rotate credentials as needed.
Yes. Use filters and field mappings to control which contacts are pulled. You can apply query parameters or conditional logic within your Zap to limit data by segment, tag, or update date. This helps keep data transfers small and relevant.
GHL APIs enforce rate limits. If you hit a limit, implement exponential backoff and retries in your Zapier app, and batch requests where possible. Monitoring tools in Zapier can alert you when usage approaches the cap.
Map fields by matching GHL contact fields (id, email, name, phone, notes) to corresponding fields in your app. Use Zapier’s data transformer steps to format values (dates, IDs) as needed and ensure data types align.
API usage metrics are available within the GHL account dashboard and your Zapier task history. Review endpoint hit rates, errors, and latency to optimize your integration.
Due to high volume, we will be upgrading our server soon!
