Authenticate requests with your GHL credentials and required scope. For read-only access, use the contacts.readonly scope; write capabilities require additional permissions.
ScreenshotOne uses the existing Zapier connection to access the GHL Contacts API. No separate login is required beyond the Zapier app connection with the appropriate scope.
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

Key elements include endpoints, authentication, triggers, actions, and data mapping between GHL and ScreenshotOne
Application Programming Interface: a set of endpoints that enable apps to communicate
A URL that represents a specific resource or action in an API
Process to verify identity and grant access to API resources
An event that starts an automated workflow
Set up a Zapier workflow to capture a screenshot when a contact is created or updated, then attach it to the contact record in ScreenshotOne
Organize screenshots by business or contact segment for quick review
Process multiple contacts in a single run to generate a summarized report
In Zapier, add a new connection to the Contacts API (GHL) using API credentials and enable the required scope
Choose endpoints such as core contact data, tasks, and notes to map fields
Run tests, verify data flows, and enable the automation
The GHL Contacts API exposes endpoints like GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and more, allowing you to read core contact data and related items. Use the endpoints listed in the Endpoints section to build your workflows. For read-only workflows, ensure the scope is contacts.readonly.
To authenticate in Zapier, establish a connection between the Zapier app and GHL using your API credentials. Select the appropriate scope for your needs (e.g., contacts.readonly for reading). The connection token is stored securely in Zapier and reused across Zaps.
With the current scope of contacts.readonly, you can read contact data but not modify it. To write or update data, you would need the contacts.write scope and corresponding permissions configured in your GHL account and the Zapier app connector.
Yes. You can update a task with PUT /contacts/:contactId/tasks/:taskId and add notes with POST /contacts/:contactId/notes. Ensure your connection has the necessary write permissions and that you provide the required identifiers and payload fields.
Rate limits depend on your GHL plan and the API usage. Plan for retries with exponential backoff in your Zaps and batch requests when possible to stay within limits. Monitor API usage in your GHL account to avoid throttling.
Test the connection by creating a simple Zap that retrieves a contact or notes data. Use the built-in test feature in Zapier to verify fields map correctly and that data flows into ScreenshotOne as expected.
Key terms: API, Endpoint, Authentication, Trigger, and Action. API is the interface that lets apps talk to each other; an Endpoint is a specific URL for a resource; Authentication verifies identity; Trigger starts an automation; Action is the result of the automation.
Due to high volume, we will be upgrading our server soon!
