What are the Azure SAS authorization parameters for copying to Azure Blobs?

I have an azcopy.exe command that I copied out of MS Azure Storage Explorer in order to use in a script. The command works perfectly, but I want to understand the querystring parameters that are being used.

?sv=2020-04-08&se=2021-10-29T15:07:01Z&sr=c&sp=rwl

I understand that sv is signed version which I found in Versioning for the Azure Storage services and that section references the other parameters but I haven't been able to locate the actual docs.

I suspect that I'm close to it, but need some help.

You can find information about SAS querystring parameters here: https://learn.microsoft.com/en-us/rest/api/storageservices/create-service-sas.

To specifically answer your question:

  • sv: This is the storage REST API version.
  • se: This is the date/time value in UTC when your SAS URL will expire.
  • sr: This is the signed resource type. In your context, sr=c means that SAS token is acquired for a blob container.
  • sp: These are the permissions included in your SAS token. Currently your signed permissions include (r)ead, (w)rite and (l)ist permissions.
