To enable the API:
- Go to the Manage > Integrations pane.
- Expand IN: from cloud services to your app.
- Enable the Enable toggle.
This enables the API for the application as a whole.
- Ensure that at least one unexpired Application Access Key is present.
Otherwise, click Create Application Access Key.
Note: Every API request must include an Application Access Key. AppSheet verifies the Application Access Key before performing the API call. This ensures that only authorized API calls are performed.
