How does the application get back the BUILD_ID or BUILD_NUMBER that their HTTP Post has caused when submitting the build request by performing an HTTP Post to the Jenkins CI Job using .../buildWithParameters?token=TOKEN
to kick off a build?
For example, if I have 6 applications running that each kick off the same Jenkins CI job, each build would get a different build_id, but how does each application know which particular build_id corresponds to their trigger request?
