Or, without a service account, by giving the default App Engine service account the "signBlob" permission. Improve this answer. Frank van Puffelen k 65 65 gold badges silver badges bronze badges. James Daniels James Daniels 6, 4 4 gold badges 22 22 silver badges 27 27 bronze badges.

This is strange. Why is it not as easy when being in admin? PS : Where can I find the 'service-account. This is because the admin-sdk does not have any Cloud Storage additions. You can get your admin-sdk service account json here console. URL generated with this method is ridiculously long. URL generated by martemorfosis proposed method is much better. Is there any function that produce that URL?
