Access to the Contacts API requires a valid GHL API key with the contacts.readonly scope. Follow the GHL docs to obtain credentials and manage them securely.
In Zapier, connect your Zapier App Connector to GHL by adding a connection and supplying your GHL API key securely. Use a vault or secure storage for credentials.
Key endpoints include: GET /contacts/:contactId, GET /contacts/, POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, DELETE /contacts/:contactId/tasks/:taskId, GET /contacts/:contactId/notes, GET /contacts/:contactId/notes/:id, GET /contacts/:contactId/appointments, POST /contacts/:contactId/tags.
Trigger: When a contact is updated in GHL, Zapier fetches the latest data to keep downstream apps in sync.
Actions: Create or update a contact in GHL via POST /contacts/ or PUT /contacts/:contactId; attach notes or tasks to the contact.
GET /contacts/:contactId
Required: contactId; optional: include tasks, notes, appointments
Trigger: New contact created in Zapier can create a new contact in GHL
Actions: Create new contacts or update existing ones via POST /contacts/ or PUT /contacts/:contactId; assign tags.
POST /contacts/
Required: email, firstName; optional: lastName, phone, businessId
Trigger: Tag changes in GHL can start a Zap to update related records.
Actions: Add or remove tags using POST /contacts/:contactId/tags; update segmented lists for campaigns.
POST /contacts/:contactId/tags
Required: contactId; tag(s)
No code required to automate CRM flows between GHL and other apps using Zapier App Connector.
Centralized data flow reduces manual entry and errors and is easy to test with Zapier workflows.
Scalable, restartable automation with retries and clear error handling.
This glossary defines terms used in GHL to Zapier integrations, including endpoints, authentication, and payloads.
An API is a set of rules that lets apps talk to each other over the web to access and modify data in GHL from Zapier.
A specific URL in an API that performs a defined operation such as retrieving a contact or updating a task.
The process of proving identity to access an API, typically via API keys or OAuth credentials.
A lightweight data interchange format used for request and response payloads in REST APIs.
Capture new form submissions and push them to GHL via the Contacts API to create and update CRM records automatically.
When a GHL task updates, trigger corresponding updates in your project management tool via Zapier.
Automatically tag contacts based on activity to drive targeted campaigns and lists.
In Zapier, add a connection and authorize access to the GHL Contacts API using your API key.
Choose triggers such as contact updates and map fields to your downstream apps.
Run tests to verify data flow and deploy your Zap for ongoing automation.
Yes, authentication is required to access the Contacts API. Use an API key with the contacts.readonly scope, and follow GHL’s recommended security practices. For most Zapier flows, a secure connection via OAuth or API key vanity credentials is used. Ensure you rotate credentials regularly and monitor activity.
Write operations exist for creating and updating contacts, tasks and notes. Endpoints like POST /contacts/, PUT /contacts/:contactId and POST /contacts/:contactId/tasks enable changes. Use the minimum required scope for your integration and protect your credentials.
Yes. You can manage contacts, tasks, notes, and tags from Zapier by configuring appropriate triggers and actions that map fields between Zapier apps and GHL’s Contacts API. Start with a read flow to sync data, then add write actions as needed.
Test connections with Zapier’s built in test feature and by running sample Zaps. If errors occur, check credential scope, endpoint paths, payload structures and field mappings. Use logging to identify where data diverges.
Rate limits depend on your GHL plan and endpoint. Plan for retries and backoff in Zapier to handle temporary throttling gracefully. If you anticipate high volume, consider batching requests where possible.
If a Zap fails, Zapier retries according to your configuration. Review error messages, validate credentials, and verify that endpoints and payloads match the GHL API spec. Update mappings as needed and re-run the Zap.
Webhooks can be used for real time updates in GHL to Zapier in supported configurations. Ensure your webhook URL is correct and that events align with your triggers in Zapier.
Due to high volume, we will be upgrading our server soon!
