To attach a file, you have to upload the file (Upload a text file) and then add the link to your work item (Add an attachment): Attach a file and create new workitem
Microsoft.VSTS.Build.IntegrationBuild is just a field without any links. You have to add ArtifactLink link with Integrated in build type: Add build link to work item using REST API
