Access to the GHL Contacts API is secured with OAuth 2.0 or an API key. Choose the scope you need (contacts.readonly or contacts.write).
Zapier App Connector authenticates to GHL on your behalf using OAuth or a dedicated API token. Keep credentials secure and rotate them regularly.
Key endpoints used in this integration include: 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, 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: a contact is created or updated in GHL so Zapier can pull the latest details
Actions: fetch full contact data, map fields, and push updates to your Zapier workflows or connected apps
Method/Path: GET /contacts/:contactId to retrieve the latest contact, along with related tasks, notes, and appointments as needed
contactId, name, email, phone, status, lastUpdated
Trigger: a new or updated note is added to a contact
Actions: transfer notes to Zapier App Connector and attach to CRM records or create follow-up items
Method/Path: GET /contacts/:contactId/notes
noteId, contactId, content, date
Trigger: a task is created or updated for a contact
Actions: sync or mirror tasks to Zapier App Connector and update statuses across apps
Method/Path: GET /contacts/:contactId/tasks
taskId, contactId, title, status, dueDate
Get up and running quickly with visual builders—no coding is required.
Automate cross-app data flows to save time and reduce manual entry.
Scale your CRM workflows safely with robust error handling and retry logic.
Data elements include contacts, tasks, notes, and appointments. Core processes cover authentication, endpoint calls, field mapping, testing, and deployment inside your Zapier App Connector workflows.
A person record in GHL that includes identifiers such as contactId, name, email, phone, and linked records like notes, tasks, and appointments.
A defined URL path used to access a specific resource in the GHL API, for example /contacts/:contactId.
An event in your automation that starts a workflow, such as a new contact or updated record.
An operation performed by automation in response to a trigger, such as creating a contact or updating a task.
Pull a weekly digest of changed contacts and post it to your team channel or dashboard for quick review.
If a task slips, trigger alerts in your project tool and assign follow-ups automatically.
Attach notes to contact records to enrich profiles and trigger personalized follow-ups.
Generate OAuth tokens or an API key in GHL and configure the Zapier App Connector with the client ID and secret, or token.
Complete the OAuth flow in Zapier to authorize access to GHL data for your account.
In Zapier, map essential contact fields (name, email, phone) and run a test to confirm data flows as expected.
No coding is required. The Zapier App Connector provides a visual interface to authenticate and map fields between GHL and your apps. This makes it easy to create powerful automations without writing code. If you want more control, you can add custom steps or filters within Zapier workflows.
At minimum, you will commonly use the following endpoints: GET /contacts/:contactId to retrieve contact data, GET /contacts/:contactId/tasks for related tasks, and GET /contacts/:contactId/notes for notes. You can also expand to POST, PUT, and DELETE for creating and updating records as needed.
Tokens are exchanged via OAuth 2.0 or API keys. GHL issues access tokens that Zapier uses to perform actions on your behalf, with refresh tokens to maintain long-lived access. Always store tokens securely and rotate them periodically.
Yes. You can sync tasks and notes in addition to contacts. Use endpoints like GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to pull related data, and map those fields into your Zapier automations.
Rate limits vary by plan but are designed for reliable automation. If you hit limits, implement exponential backoff in your Zapier workflows and stagger requests to avoid failures.
Use test utilities in Zapier’s editor to simulate triggers and actions. You can also run a dry run against the GHL API to verify authentication, permissions, and field mappings before going live.
API credentials are created in your GHL account and managed in the API credentials area. If credentials expire or are rotated, re-run the OAuth flow in Zapier to restore access and update your app configuration.
Due to high volume, we will be upgrading our server soon!
