Retrieving ACR image SHA using Azure REST API

Question

I am trying to retrieve the SHA (digest) from an ACR image with a specific tag using Azure API. I am able to use the manifests API to get digests for the manifests of a tag, however, this is not digest I am after.

I would like to retrieve the digest that is clearly visible under the "Essentials" tab of the image tag page in Azure Portal (see image).

I am wondering if there's a way to use the API to get this digest. I would like to avoid using AZ CLI or pulling the image.

Hello Samuel Thelaus

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

I just tried by passing the repository name and I am able to get the Digest SHA value that is shown under the essentials of ACR image on Azure portal https://learn.microsoft.com/en-us/rest/api/containerregistry/tag/get-attributes?view=rest-containerregistry-2019-08-15&tabs=HTTP

GET {url}/acr/v1/{name}/_tags/{reference}

Hope this helps.
