How can I retrieve the build parameters used when a build was triggered in VSTS (using the REST API)?

Question

I'm trying to figure out how to retrieve the build parameters that were used when a build was triggered in VSTS (using the REST API).

I'm successfully retrieving builds using the following query:

https://{accountName}.visualstudio.com/{project}/_apis/build/builds

... but in the response I can't find the parameters that were used.

Answer 1

Just found the parameter key value pairs in the 'parameters' property
