Use OAuth 2.0 to authorize the Zapier App Connector to access your GHL Contacts data. Obtain client credentials, authorize the application, and store tokens securely in Zapier.
In Zapier, connect your app using OAuth or API key, then select the GHL Contacts API as the action source. Authenticate once and reuse connections for automations.
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, GET /contacts/ (list), 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
When a contact is added or updated in GHL, the Zapier App Connector can trigger an automation in your workflow.
Actions: Create or update contact, add notes, schedule tasks, or fetch contact data to drive downstream steps.
GET /contacts/:contactId
Key fields: id, email, firstName, lastName, phone
Trigger when a contact field changes or a note is added to keep data synchronized.
PUT /contacts/:contactId
Fields: email, firstName, lastName, phone, status
Trigger when a calendar event is created in GHL to schedule an appointment in Zapier workflow.
Actions: Create appointment in GHL from KingSumo data, or push appointment updates.
POST /contacts/:contactId/appointments
Fields: appointmentTime, date, location, notes
No coding required — leverage visual workflow builders to connect GHL with Zapier.
Faster release cycles — deploy automations in hours, not weeks.
Scalable automation — easily add more endpoints and actions as needs grow.
Understand the core elements: endpoints, triggers, actions, methods, and fields used to stitch GHL Contacts API into your KingSumo workflows via the Zapier App Connector.
A URL path and HTTP method that lets you access or modify a resource in an API.
An event that starts an automation in your workflow.
An operation performed by the automation in response to a trigger.
The process of verifying identity and granting access to API resources.
Automatically create or update a contact in GHL when a new lead comes from KingSumo, then enroll them into a follow-up sequence.
Create follow-up tasks in GHL when milestones occur in KingSumo campaigns, helping your team stay on track.
Push KingSumo events to GHL as appointments to streamline scheduling.
Register your application in GHL and authorize the Zapier App Connector to access Contacts data.
Select a trigger such as contact creation or update to start your workflow and map fields from GHL to KingSumo.
Define actions like creating a contact, adding notes, or scheduling tasks, and test the integration.
The GHL Contacts API allows you to read and write contact records, tasks, notes, and appointments. It enables programmatic access to core CRM data for automations and integrations. Use endpoints like GET /contacts/:contactId to fetch a single contact and GET /contacts/ to list contacts.
No-code automation is possible here. The App Connector and the Zapier platform provide a visual workflow builder that lets you connect GHL without writing code. You may need some configuration, but no traditional coding is required.
Common endpoints used for syncing include GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, and GET /contacts/:contactId/tasks. These cover core CRM data like contacts, tasks, and notes.
Yes. You can create or update tasks in GHL from KingSumo via the Zapier App Connector, triggering automation workflows based on KingSumo events or participant actions.
The integration uses standard HTTPS with OAuth tokens to authorize requests. Store credentials securely and rotate tokens periodically to maintain security.
To test the connection, create a test Zap, connect both apps, run a test action, and verify data in GHL. Use sample data to ensure mappings are correct.
API limits depend on your GHL plan. Review your plan’s rate limits in the GHL developer docs and monitor usage via the Zapier task history.
Due to high volume, we will be upgrading our server soon!
