Use OAuth 2.0 with the scope: contacts.readonly to access contact data securely. When write access is needed, ensure appropriate permissions are granted.
ClassMarker stores your connected app credentials to securely authenticate requests to the GHL API. Use the Zapier App Connector to manage tokens and secure headers.
Key endpoints 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. Write operations include 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, and POST /contacts/:contactId/tags.
Trigger on new or updated contacts in GHL to sync ClassMarker and start related workflows.
Actions: ensure a matching ClassMarker contact exists, then create or update tasks and attach notes as needed.
Use POST /contacts/ to create contacts, PUT /contacts/:contactId to update, and GET /contacts/:contactId to fetch.
Key fields: contactId, name, email, phone, company, ownerId.
Trigger when a task is created or updated under a contact in GHL.
Actions: create or update corresponding tasks in ClassMarker and reflect status changes.
POST /contacts/:contactId/tasks to create tasks; PUT /contacts/:contactId/tasks/:taskId to update.
Key fields: contactId, taskId, title, dueDate, status.
Trigger on notes added to a contact in GHL.
Actions: create notes in ClassMarker and apply relevant tags.
POST /contacts/:contactId/notes to create notes.
Key fields: contactId, noteId, content, createdAt, tagIds.
Automate data flow without writing any code in between GHL and ClassMarker.
Create real-time workflows across apps using Zapier App Connector.
Maintain synchronized contact, task, and note data across systems.
This glossary covers endpoints, triggers, actions, and field mappings used to connect the GHL Contacts API with ClassMarker.
An API endpoint is a specific URL path that performs a defined operation (read, write, delete) on resources.
The process to verify identity and grant access to the API, typically using OAuth 2.0.
GET, POST, PUT, DELETE and other methods describe the action to perform on an endpoint.
A callback URL that is triggered by events to notify another system.
When a new contact is created in GHL, automatically create a corresponding ClassMarker profile, assign starter tasks, and add a welcome note.
Push task status changes from GHL to ClassMarker to keep teams aligned and up to date.
Apply ClassMarker tags based on GHL data fields to enable targeted workflows and reporting.
Authorize GHL and securely connect to ClassMarker via the Zapier App Connector.
Link GHL contact fields to ClassMarker fields and choose relevant endpoints to automate data flow.
Create zaps, test mappings, and monitor logs to ensure reliable automation.
The Contacts API provides access to contact records, tasks, notes, appointments, and business data. The read-only scope allows you to view data; write endpoints are available if you have the necessary permissions to create, update, or delete records. Use appropriate endpoints to fetch or modify data as your workflow requires.
No extensive coding is required when using the Zapier App Connector. You can design automations with a visual editor by mapping fields and endpoints. A basic understanding of the endpoints helps you tailor workflows to your needs.
Start with GET /contacts/:contactId to pull existing data, then use POST /contacts/ to create new records or PUT /contacts/:contactId to update. For task automation, leverage POST /contacts/:contactId/tasks and related note endpoints to build out workflows.
Yes. Use PUT to update existing ClassMarker records and POST to create new ones. Ensure you map the correct contactId and related fields to maintain data consistency across systems.
Authentication uses OAuth 2.0 with the required scopes. Tokens should be stored securely and refreshed as needed. The Zapier App Connector handles token management for you.
Rate limits depend on your GHL plan and endpoint type. Implement retries with exponential backoff and monitor usage via logs to avoid interruptions.
Test in a staging or sandbox environment when available. Use Zapier’s test feature to simulate triggers, verify mappings, and confirm that data flows correctly between GHL and ClassMarker.
Due to high volume, we will be upgrading our server soon!
