Hello @Rohit ,

Thanks for the question and using MS Q&A platform.

> To connect to a storage account using a system-assigned managed identity, you need to specify the resource URL for the storage account in the web activity. The resource URL for the storage account will be in the following format: https://storage.azure.com/

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/

Note: The resource url changes from service to service.

For more details, refer to Web activity in Azure Data Factory and Azure Synapse Analytics, Using Azure Data Factory to call Azure REST API of Azure API Management and How to Read File from Blob Storage and Save Contents in Variable in ADF Azure Data Factory Tutorial.

Hope this will help. Please let us know if any further queries.

Hello @PRADEEPCHEEKATLA

Thankyou for your reply.

As you mentioned that the URL Changes from Service to Service, can you let me know where did you find these details, is there a common place where we can find the list of URL for the services for my future reference ? I need to do this for multiple offerings/services, so the dictionary/list would be really helpful.

Hello @Rohit,
I could not find a single document which clearly mentions all the list of resource URL for all the Azure Services. I think you have to check the official documentation for REST API individually for every service to get the resource URL.
