This endpoint allows you to update your current settings for open tracking.
Open Tracking adds an invisible image at the end of the email which can track email opens.
If the email recipient has images enabled on their email client, a request to SendGrid’s server for the invisible image is executed and an open event is logged.
These events are logged in the Statistics portal, Email Activity interface, and are reported by the Event Webhook.
- API Key
on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g.,
on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g.,
on-behalf-of: <subuser-username>). See On Behalf Of for more information.
