Authenticate using the GHL credentials with the required scope: contacts.readonly. Keep credentials secure and rotate keys regularly.
In the Zapier App Connector, configure OAuth or an API key based on your setup, ensuring access to the Contacts API endpoints.
GET /contacts/:contactId — Retrieve a contact by ID; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Get a specific task; GET /contacts/:contactId/notes — List notes for a contact; GET /contacts/:contactId/notes/:id — Get a note; GET /contacts/:contactId/appointments — List appointments; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List contacts for a business; contacts.write — permission to write to contacts; POST /contacts/ — Create a new contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task completed; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact.
Trigger: New or updated contact in GHL triggers a Zap to pull contact data, tasks, and notes.
Actions: Retrieve contact, list tasks and notes, then update your downstream systems.
GET /contacts/:contactId
Key fields: contactId, taskId, noteId
Trigger: Contact updated.
Actions: Update contact, update notes, and sync with your CRM.
PUT /contacts/:contactId
Key fields: contactId, noteId
Trigger: New contact created.
Actions: Create contact, create initial tasks.
POST /contacts/
Key fields: contactId, taskId (for initial tasks)
Rapid setup with no-code automation and prebuilt actions.
Maintain data consistency across systems via webhook-like triggers.
Scale workflows easily as your contacts grow.
This section defines core elements: endpoints, triggers, actions, and data fields used to build Zapier-powered workflows with the GHL Contacts API.
The GHL API provides programmatic access to contacts, notes, tasks, appointments, and other CRM data.
A specific URL path that performs an action on a resource in the GHL API.
A person stored in GHL with personal details and related activity data.
A to-do item tied to a contact, used to track progress.
Pull contact data via GET /contacts/:contactId and enrich with notes and tasks for a richer profile in your CRM.
On new contacts, automatically create onboarding tasks using POST /contacts/:contactId/tasks.
Sync contact updates with external systems by triggering PUT /contacts/:contactId and related endpoints.
Obtain API keys or OAuth credentials for GHL and enter them in the Zapier App Connector.
Use sample GET requests to verify access and data structure.
Create a Zap with a GHL trigger and actions to map fields to your app.
The GHL Contacts API gives access to core CRM data, including contacts, tasks, notes, and appointments. It enables read-only access with the appropriate scopes. To perform writes, you will need write permissions granted by the API credentials. In Zapier App Connector, authenticate with GHL and use the GET endpoints to read data, then POST/PUT requests to update or create records. Always respect rate limits and security best practices when building automations.
You typically need the contacts.readonly scope for reading and the contacts.write scope for creating or updating records. Ensure your OAuth or API key has the necessary permissions before attempting write operations. In Zapier, select the correct authentication method and test changes in a sandbox or test Zap before going live to avoid unintended data changes.
Yes. Reading data is allowed with read permissions, and writing data is possible with write permissions on the correct endpoints. Use GET for reads and POST/PUT/DELETE for writes as appropriate. Always validate responses in Zapier’s test tool to confirm payload structure and field mappings before deploying.
In Zapier, use the built-in Test action in the trigger or action step to run sample API calls and inspect responses. Check status codes, response shapes, and error messages to adjust mappings. Use test data that mirrors your production data to ensure reliability in your automations.
Onboarding workflows benefit most from endpoints around contacts, tasks, and notes, since you typically create a contact and then seed onboarding tasks. Use a trigger on new contacts and orchestrate subsequent actions to create tasks and notes as needed. Map fields carefully so downstream apps receive a clean, consistent data model.
This integration is designed for no-code users via Zapier. Many common tasks can be achieved with triggers, actions, and field mappings in the UI. Some advanced scenarios may require light scripting or additional Zaps for complex transformations. If you run into limitations, you can augment with custom webhooks or small code steps in Zapier’s Code by Zapier feature.
Data mapping is shown in Zapier’s editor under each action and trigger. You can view available GHL fields when configuring the step and map them to your destination app. Documentation also provides field names and example payloads for reference.
Due to high volume, we will be upgrading our server soon!
