Use your GHL API key with the Contacts API to authorize requests. Ensure the correct scope (such as contacts.readonly) is granted and store credentials securely in your vault or credential store.
Authenticate via OAuth 2.0 in the App Connector, providing a client ID and client secret. Test the connection to confirm access to the Contacts endpoints and verify token validity.
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 on new or updated contacts in GHL to start a workflow in the App Connector.
Actions include creating or updating the contact in GHL and pushing updated data to downstream apps.
Example: GET /contacts/:contactId to fetch latest data for sync.
Key fields include contactId, email, firstName, lastName, phone.
Trigger when a task or note is created or updated in GHL to trigger actions in App Connector.
Actions include creating/updating tasks and notes, tagging contacts, and syncing activity data.
Example: PUT /contacts/:contactId/tasks/:taskId for updating a task.
Key fields: taskId, contactId, status, dueDate.
Trigger: webhook events from GHL to App Connector when endpoints fire.
Actions: create notes, update contacts, or trigger downstream automations.
Example: POST /contacts/:contactId/notes to add a note.
Key fields: noteId, contactId, type, content.
Automate data flow without writing code using prebuilt triggers and actions.
Reduce manual data entry by keeping contacts, tasks, and notes in sync across apps.
Scale workflows quickly with endpoint-rich automation and no custom coding required.
This section covers authentication, endpoint usage, triggers, actions, field mapping, and error handling to help you build reliable automations.
Granting access to the GHL API to perform operations on Contacts.
A specific API route, such as GET /contacts/:contactId.
A real-time event notification that triggers automations.
OAuth 2.0 protocol used to authorize apps to access user data securely.
Capture new form responses and automatically create or update Contacts in GHL via the API.
When a task is created in GHL, push to downstream apps via App Connector to trigger follow-up.
Aggregate notes from contacts into a unified workspace in Zapier for quick reference.
Obtain your GHL API key and configure OAuth in the App Connector.
Run a test call such as GET /contacts or GET /contacts/:contactId to verify connectivity.
Create a simple Zap: on new contact, update a task or add a note to illustrate end-to-end automation.
No code is required for many common flows thanks to prebuilt actions and triggers in the App Connector. You can map fields and configure simple automations without writing a line of code. If you need more advanced transformations, you can add optional steps or use built-in functions to shape data before it moves to downstream apps.
Core endpoints like GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and POST /contacts/ support typical CRM workflows. Use tasks and notes endpoints to keep activities in sync, and leverage tags and business endpoints for organization.
Authentication is handled via API keys for server-to-server calls or OAuth for user-consent scenarios. Keep credentials secure, rotate tokens regularly, and apply the principle of least privilege by restricting scope to what you need (for example, contacts.readonly).
Yes. You can trigger updates in real time using webhooks or near real-time polling depending on the endpoint. This enables immediate propagation of changes to tasks, notes, and contact data across connected apps.
Rate limits depend on your GHL plan and API tier. Plan for bursts during peak automation and implement exponential backoff in your App Connector workflows to handle retries gracefully.
Absolutely. Field mapping lets you align GHL contact fields with your App Connector fields. You can map standard fields like email, name, and phone, plus custom fields, ensuring data consistency across systems.
API documentation is available in the GHL developer portal and within the App Connector’s connected app docs. Refer to the Contacts API section and the endpoint reference for details on parameters and responses.
Due to high volume, we will be upgrading our server soon!
