Does OAuth2 (Authorization code) authentication have any limitations for making any CRUD requests to the BLOB STORAGE API?

Question

Hello,

Is OAuth2 authentication suitable for making requests to Azure Blob Storage? Does it have any kind of limitation for this?

Also I noticed that OAuth2 (Authorization code) doesn't seem to return a refresh token with the access token that I could use to retrieve another access token when the one received expires. Is this the expected behaviour?

Yes it is one of the recommend method for authorization and access to Azure Blobs. Please refer to Authorize access to blobs and queues using Azure Active Directory for more information. We also have examples and more information about how to acquire a token on this page.

After requesting an access token you should be given a refresh token. Which can then be used to refresh the access token.

Hope this helps! If you have further questions or issues please let us know.

Thank you for the links Deherman. It seems I wasn't adding the offline_access scope to my request next to https://storage.azure.com/user_impersonation scope. Now I receive a refresh token with the access token.
