How to get agent information of a build by using rest api?

[Golla Sai Venkatesh]

I want to know on which agent a build was run using bamboo REST API

I tried with agent assignment API, but it will give the project, plan or job it is assigned to. But I want which agent from set of capability matching agents ran the build?

[Nicolas Mertens]

it should work via https://developer.atlassian.com/server/bamboo/rest/api-group-api/#api-api-latest-result-projectkey-buildkey-buildnumber-get.

buildSummary-Response should include buildAgentId 

But exactly buildAgentId is missing in response (tested with 8.1.6 build 80114)
