Documented steps
POST to the build's own URL with /stop appended (JENKINS_URL/job/JOB_NAME/BUILD_NUMBER/stop) to abort a running Pipeline - this interrupts the build's executor thread.
If /stop has no effect, POST to .../term instead: the docs describe this as forcibly terminating a build, to be used only if stop does not work.
As a last resort, POST to .../kill: the docs call this the most destructive way to stop a pipeline, to be used only when stop and term both fail.
Authenticate the POST the same way as any other modifying call - API-token Basic auth needs no crumb; session/cookie auth needs the crumb+cookie flow.
If the build still won't stop, check JENKINS_URL/threadDump to see where the executor thread is actually blocked.
stop/term/kill are documented specifically for Pipeline builds - no equivalent freestyle-build endpoints are described on that page.
Not every wait is interruptible: the docs note that waiting for file or network I/O is not an interruption point, so a build can look un-abortable even right after /stop is called.
term and kill are explicitly framed as escalating, more destructive fallbacks, not first choices - always try /stop first.
Cancelling a build that is still QUEUED (not yet started) is a different call: POST JENKINS_URL/queue/cancelItem?id=<id> (Queue.doCancelItem in the Jenkins javadoc), with the id taken from /queue/api/json.
