Obtain OAuth 2.0 credentials or an API key for the Contacts API to securely authorize requests from Zapier App Connector.
Create a new connection in Zapier, select the Contacts API as the resource, and configure the OAuth 2.0 or API key flow.
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: when a contact is updated in GHL to keep related tasks and notes in sync.
Actions: create or update tasks, add notes, and update the contact’s fields in Zapier.
Method paths: GET /contacts/:contactId to fetch, POST /contacts/:contactId/tasks to create tasks, GET /contacts/:contactId/notes to fetch notes.
Key fields: contactId, taskId, notesId, businessId.
Trigger: new or updated contact triggers note creation.
Actions: create or update notes linked to the contact.
Methods: GET /contacts/:contactId/notes, GET /contacts/:contactId to fetch the contact.
Key fields: contactId, id (note).
Trigger: when a contact is tagged or untagged.
Actions: add or remove tags on the contact.
Methods: POST /contacts/:contactId/tags (tag management).
Key fields: contactId, tag IDs.
Automate repetitive workflows without writing code.
No-code data synchronization between GHL and other apps via Zapier.
Quickly test and deploy automations with built-in connectors.
Definitions for terms like endpoints, triggers, actions, and fields used in the GHL Contacts API integration.
A unique identifier assigned to a contact within GHL.
A unique identifier for a task linked to a contact.
A specific API URL path used to perform an operation.
The permission level requested for an API call (e.g., readonly).
Pull external data to enrich contact records as they change.
Create tasks automatically when deal stages update.
Synchronize notes across GHL and Zapier for a single source of truth.
In Zapier, add a new connection and select the Contacts API as the resource.
Map triggers (contact update) and actions (create task, add notes) to your workflow.
Test data flows, verify results, and deploy to automation pipelines.
The Contacts API lets you read and manage contact records in GHL, including retrieving details, tasks, notes, and tags. This no-code approach via Zapier App Connector enables you to create, update, and sync data across apps without coding. You can tailor workflows to automatically keep records up to date across your tech stack.
To authenticate the GHL API from Zapier, you typically use OAuth 2.0 or an API key. In Zapier, create a new connection and supply the credentials, then authorize the connection to access the Contacts API with the configured scope. Store credentials securely and rotate them per your security policy.
Available endpoints include reading contacts, tasks, notes, and tags, as well as creating and updating contacts and tasks. You can also fetch business details and manage contact-level resources like tags and notes. Use the endpoints to build robust, no-code automations.
Yes, the API supports write and delete operations for contacts and related resources, such as creating new contacts, updating them, deleting, or managing tasks. Ensure your connection has the proper scope (e.g., write access) to perform these actions.
Tagging support allows you to add or remove tags on contacts via POST /contacts/:contactId/tags. This enables tagging-based segmentation and workflow triggers when tags change. Use tags to drive targeted automations across apps.
Error handling uses standard HTTP status codes and structured error messages. Plan for rate limits by implementing retries with backoff and respect retry-after headers. Zapier provides tooling to manage errors and backoff strategies.
Yes, you can test the integration in a sandbox or with test data before going live. Use Zapier’s test features to validate triggers, actions, and data mapping without impacting real records.
Due to high volume, we will be upgrading our server soon!
