How to set expiry/TTL for file uploaded to Azure Blob Storage using Azure Client?

Hi Azure team,

I have looking to figure out ways one can use to set some expiry/Time to live for a file uploaded in the Azure Blob. So far, I have come across:

  1. Enabling storage lifecycle management using dashboard (https://learn.microsoft.com/en-us/azure/storage/blobs/storage-lifecycle-management-concepts?tabs=template)
  2. Enabling soft delete a blob using dashboard again (https://learn.microsoft.com/en-us/azure/storage/blobs/soft-delete-blob-overview)
  3. Setting blob expiry using a PUT call (https://learn.microsoft.com/en-us/rest/api/storageservices/set-blob-expiry)

I was wondering if it's possible to do so using the azure client itself instead of us having to making changes to dashboards or using the REST PUT call. This will provide flexibility for us to set expiry time at runtime without having to go and make these static changes.

Awaiting your response.
Thanks

    1. create retention rule:

    {"rules":[{"enabled":true,"name":"DeleteArtiTmp","type":"Lifecycle","definition":{"actions":{"baseBlob":{"delete":{"daysAfterCreationGreaterThan":1}}},"filters":{"prefixMatch":["somepath/"],"blobTypes":["blockBlob"],"blobIndexMatch":[{"name":"ttl","op":"=","value":"oneDay"}]}}},{"enabled":true,"name":"DeleteArtiLng","type":"Lifecycle","definition":{"actions":{"baseBlob":{"delete":{"daysAfterCreationGreaterThan":5}}},"filters":{"prefixMatch":["somepath/"],"blobTypes":["blockBlob"],"blobIndexMatch":[{"name":"ttl","op":"=","value":"fiveDays"}]}}}]}

    1. enable indexing on the azure blob storage container.
    2. add metadata KV to files during upload: ttl=oneDay or ttl=fiveDays
