I am using the Azure DevOps REST API, for example:
curl -X GET 'https://dev.azure.com/MyOrg/MyProject/_apis/pipelines/ID/runs/ID?api-version=6.0-preview.1'
In the result, there does not seem to be any mention of the parameters passed into the pipeline, or the build cause/reason. I've tried setting variables to the value of the parameters and that doesn't seem to show up either, and fiddling with the API version string hasn't yielded anything.
Is there a way to programmatically retrieve information about trigger reason and parameters using the API? Without this, it seems impossible to build any backend data (for example, to show the % of users using your pipeline via the azure portal or via PR triggers).
