Automating Email Attachment Uploads to Azure DevOps Work Items via Power Automate

This article assumes you know how to implement the following steps first:

1. When a new email arrives (V3) - Outlook 365 action
2. Create a work item - DevOps action
3. Apply to each using Attachments list - Outlook 365 dynamic content item
   • Send HTTP POST request to DevOps to upload the attachment file content - DevOps action
   • Parse JSON - regular action
   • Send HTTP POST request to DevOps to associate uploaded file to the work item - DevOps action

There is an issue at step 3. a where the attachment is being uploaded. Attachments can be of various content types, and additionally (but separately) you are having to decide whether the body is Base64 or not.

Steps:

1. Organization Name - your org name
2. Method - POST
3. Relative URI - /_apis/wit/attachments?filename=[Attachment Name dynamic content item]&api-version=7.1
4. Headers - Only one header: content-type of value items('Apply_to_each')?['contentType']
5. Body - binary(items('Apply_to_each')?['contentBytes'])
6. Body is Base64: Yes
