To access the Contacts API, obtain an API key or OAuth token with the necessary scopes (for example, contacts.readonly or contacts.write). Use token-based authentication in your Zapier app and rotate credentials regularly.
In Zapier, connect the Zapier App Connector to your GHL account by supplying credentials and selecting the correct scopes. Confirm permissions before triggering any reads or writes.
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; contacts.write; 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: When a contact is created or updated in GHL, Zapier pulls the latest data to start a workflow.
Actions: Retrieve full contact records (GET /contacts/:contactId), then create or update the contact in your destination app using POST /contacts/ or PUT /contacts/:contactId.
Method paths: GET /contacts/:contactId; GET /contacts/; POST /contacts/; PUT /contacts/:contactId
Key fields: contactId, email, name, phone, tags
Trigger: Updates in GHL can create tasks via the tasks endpoints in Zapier.
Actions: Create tasks with POST /contacts/:contactId/tasks; mark completion with PUT /contacts/:contactId/tasks/:taskId/completed.
Method paths: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId/completed
Key fields: contactId, taskId, status
Trigger: Notes or tags changes in GHL trigger automations in Zapier.
Actions: Create notes with POST /contacts/:contactId/notes; add tags with POST /contacts/:contactId/tags.
Method paths: GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; POST /contacts/:contactId/tags
Key fields: contactId, noteId, tag
Automate data transfer without writing code between GHL and Zapier
Eliminate manual data entry with triggers and actions built visually
Scale workflows across teams with consistent data sync
Understand the core parts of a GHL-to-Zapier integration: endpoints, authentication, data objects, and common workflows.
A specific URL in the GHL Contacts API used to perform a function such as retrieving a contact or updating a task.
The process of proving your app or user has permission to access GHL data, typically via tokens.
An individual in your GHL CRM with associated data like notes, tasks, and activities.
A URL that receives real-time event notifications to trigger automations.
Fetch all contacts, identify duplicates, and automatically merge or tag for review using Zapier workflows.
Create tasks in GHL when triggers fire in Zapier, ensuring teams stay aligned.
Auto-attach notes and tags to contacts based on events, surfacing context for teams.
Connect GHL Contacts API in Zapier by providing credentials and selecting the correct scopes (e.g., contacts.readonly, contacts.write).
Choose triggers from the Contacts API (e.g., new or updated contact) and define actions using the appropriate endpoints.
Run tests, validate data flows, and deploy the automation with logging and alerting.
The GHL Contacts API is a set of endpoints that let you read and manage contact data, tasks, notes, and more from your GHL account. It enables programmatic access for automation and integration with external apps. By using the GHL API, you can synchronize contacts to your CRM, trigger actions in downstream systems, and build custom workflows without manual data entry.
Authentication is token-based. Obtain an access token with the required scopes and include it in the Authorization header of each request. In Zapier, securely store the token and rotate credentials as needed, using OAuth when supported for user-by-user access.
Common endpoints to start with include GET /contacts/:contactId to fetch details and GET /contacts/ for listing. The POST and PUT variants enable updating and creating data as part of automation. Refer to the API docs for exact field requirements and response formats to design reliable automations.
Yes. You can create new contacts, update existing ones, and manage related resources like tasks and notes from Zapier using endpoints like POST /contacts/ and POST /contacts/:contactId/tasks. Ensure you have the right permissions and test changes in a staging environment before production.
Common errors include invalid tokens, missing scopes, and rate limit responses. Validate credentials and endpoints in your Zap, then enable logging and retries. Set up alerting to catch failures quickly.
GHL API usage is governed by rate limits that protect the service. If you hit a limit, implement exponential backoff and retry policies. Plan automation to minimize calls and consider batching where feasible.
Sample payloads typically include a contact object with fields like id, name, email, and associated tasks or notes. Use the API docs to confirm required fields for each endpoint. Zapier templates or webhooks can provide starter payloads you can adapt for your workflow.
Due to high volume, we will be upgrading our server soon!
