Use the Check Email Stats endpoint to review the complete details for an email sent as part of an Apollo sequence. This includes the contents of the emails, stats related to the email such as opens and clicks, and details about the contact that received the email.
This endpoint requires a master API key. If you attempt to call the endpoint without a master key, you will receive a 403 response. Refer to Create API Keys to learn how to create a master API key.
