VerifyEntitlementTokenRequest.EntitlementToken property

Important

While the app license token is structured as an XML fragment, for purposes of validation the Office Store verification web service treats the token as a literal string. The Office Store verification web service compares the contents of the <t> element to the value of the <d> element, which is an encrypted signature derived from the literal string contained in the <t> element. Any reformatting of the license token, such as adding white space, tabs, line breaks, etc., will change the literal value of the <t> element and therefore cause the license verification check to fail. Developers are advised not to parse or otherwise manipulate the app license token string before passing it to the Office Store verification web service for verification.

When you submit a test app license token to the Office Store verification web service, the service does not perform that validation check of comparing the encrypted signature in the <d> element to the string contained in the <t> element. This enables developers to create their own test app license tokens for testing purposes without worrying about formatting, or generating the encryption signature for the <d> element.
