requestIdentifier
A string that contains a unique identifier you provide to track each subscription-renewal-date extension request.
Declaration
string requestIdentifierDiscussion
You provide a requestIdentifier in the request body when you call the Extend Subscription Renewal Dates for All Active Subscribers and Extend a Subscription Renewal Date endpoints.
The API returns the same request identifier in its response, so you can match your request with the related response. The App Store Server Notifications V2 also include this request identifier in notifications related to the Extend Subscription Renewal Dates for All Active Subscribers endpoint. For more information, see the RENEWAL_EXTENSION notificationType.
To resend the same request due to a timeout or other error, use the same request identifier. Otherwise, create a unique request identifer for each different subscription-renewal-date extension request.
The maximum string length is 128 characters.
