Requests to the Contacts API must be authenticated. Use an API Key or OAuth 2.0 token with the scope contacts.readonly to access contacts, tasks, notes, appointments, and related data.
In Zapier, connect your GHL account once and reuse the connection across steps. OAuth 2.0 is used to securely authorize access to your data without sharing credentials.
GET /contacts/:contactId — Retrieve a single contact.\nGET /contacts/:contactId/tasks — List tasks for a contact.\nGET /contacts/:contactId/tasks/:taskId — Retrieve a specific task.\nGET /contacts/:contactId/notes — List notes for a contact.\nGET /contacts/:contactId/notes/:id — Retrieve a specific note.\nGET /contacts/:contactId/appointments — List appointments for a contact.\nGET /contacts/ — List contacts.\nGET /contacts/business/:businessId — List contacts by business.\ncontacts.write — Scope for write access.\nPOST /contacts/ — Create a new contact.\nPUT /contacts/:contactId — Update a contact.\nDELETE /contacts/:contactId — Delete a contact.\nPOST /contacts/:contactId/tasks — Create a new task for a contact.\nPUT /contacts/:contactId/tasks/:taskId — Update a task.\nPUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed.\nDELETE /contacts/:contactId/tasks/:taskId — Delete a task.\nPOST /contacts/:contactId/tags — Tag a contact.
Trigger: when a contact is created or updated in GHL, Zapier pulls the latest data to drive downstream actions in connected apps.
Actions: create or update a contact in GHL, fetch related tasks, attach notes, or update appointments in synchronized tools.
Use endpoints like GET /contacts/:contactId and PUT /contacts/:contactId to keep data in sync across platforms.
Key fields: contactId, email, phone, businessId.
Trigger: a new or updated task on a contact fires a Zap to update project boards or calendars.
Actions: create, update, or delete tasks; mark tasks as completed; propagate changes to your project tools.
Paths include /contacts/:contactId/tasks and /contacts/:contactId/tasks/:taskId, including /contacts/:contactId/tasks/:taskId/completed.
Key fields: contactId, taskId.
Trigger: notes or appointments updated for a contact, enabling downstream workflows.
Actions: create notes, fetch notes, fetch appointments, update related business data as needed.
Paths: /contacts/:contactId/notes and /contacts/:contactId/appointments.
Key fields: contactId, noteId, appointmentId.
Automate repetitive workflows without writing code using drag-and-drop triggers and actions in Zapier.
Keep data synchronized across tools with reliable, testable automations and centralized control.
Scale processes quickly with reusable templates and secure connections via OAuth.
This glossary defines API Endpoints, OAuth 2.0, contactId, and other terms used to connect GHL with the Zapier App Connector.
A specific URL path and HTTP method used to perform an action on the server.
An authorization framework that grants access tokens without sharing credentials.
A unique identifier for a contact within GHL.
Notes are text records linked to a contact that can be created and retrieved via the API.
Detect duplicates, merge fields, and normalize data to keep your Contacts in sync across apps with minimal manual effort.
Automatically create or update tasks in your project tool when a task is added in GHL, ensuring teams stay aligned.
Send alerts to Slack or email when notes or appointments change to keep everyone informed.
In Zapier, create a new connection to GHL via OAuth, selecting the Contacts API scope you need.
Select endpoints like GET /contacts/:contactId and POST /contacts/ and map GHL fields to Zapier fields.
Run tests, validate mappings, and deploy your Zap to automate workflows.
The Contacts API supports API Key authentication and OAuth 2.0 tokens. In the Zapier App Connector, you can connect using OAuth 2.0 and specify the necessary scopes; for read-only access, use the contacts.readonly scope. If you need write access, request the appropriate scopes for contacts, tasks, notes, and appointments. If you run into issues, verify credentials, ensure the connection is active, and review API error codes for guidance.
For syncing contacts, use endpoints such as GET /contacts/:contactId to fetch a single contact, GET /contacts/ to list contacts, and GET /contacts/business/:businessId to pull contacts by business. Map fields in Zapier to align contact data with your destination apps. If you manage related data, also pull tasks and notes with the corresponding endpoints.
In Zapier, use the field mapping interface in each action to align GHL fields with your target app. Common mappings include name, email, phone, and custom fields. For derived values, use Zapier’s built-in utilities to transform data during the workflow.
Rate limits depend on your GHL plan and Zapier usage. To minimize hits, batch requests when possible and prefer polling intervals that fit your needs. Where supported, use webhooks or event-driven triggers to reduce constant polling.
Use Zapier’s Test feature to simulate steps with sample data. Validate that mappings are correct, then run a full test Zap to confirm end-to-end flow. If errors occur, review the API response codes and adjust credentials or field mappings accordingly.
Yes. You can configure multiple triggers for notes, appointments, or tasks within a single Zap or across multiple Zaps. This allows different teams to respond to changes in real time.
Handle API errors by inspecting HTTP status codes, retrying with exponential backoff, and using Zapier’s error handling features. Keep a logs trail to diagnose failures and adjust mappings or permissions as needed.
Due to high volume, we will be upgrading our server soon!
