azure data factory web activity properties

Question

I want to use a web activity to access my storage account and I want to used System Managed Idenity to authenticate but I don't know what to write in the Resource field.

Am I supposed to put the resource the data factory trying to access to, the storage, or the resource who is accessing, the data factory?

Answer 1

In your storage account,

• Add role assignment with a role as Storage Blob Data Contributor.
• Assign access to Managed identity
• Select Member and add your data factory as a member.

In Azure data factory web activity:

• Provide the URL of your blob as below.

  ex: https://storageaccountname.blob.core.windows.net/containername/filename

• Method: GET

• Add headers

  x-ms-version: 2017-11-09

  xs-ms-blob-type: BlockBlob

• Authentication: System Assigned Managed Identity

• Resource: https://storage.azure.com/
