Hi Ralph,
I want to deliver selective changesets from StreamA to StreamB [Not all]
I use WorkspaceA and complete delivering all my changes into StreamA. Now in order to deliver changes from WorkspaceA to StreamB, Changesync+deliver API doesnt provide an option to choose changesets to deliver [It will sync up StreamA and StreamB]
I am looking to deliver only certain changesets from StreamA to StreamB using API. Please advise.

All I can provide is https://rsjazz.wordpress.com/2013/09/30/delivering-change-sets-and-baselines-to-a-stream-using-the-plain-java-client-libraries/

Note that a stream is 99% the same as a repository workspace, so that code should work. You can compare the two streams and get a set of change sets. Maybe operate on that?

I don't have code to search for a specific change set.

However, I am aware that a similar other question was here on the forum.

Note, please try to put a little bit more effort into your questions and describe what you want to do and why.

I am looking for an API equivalent to CLI:"scm deliver -c"
where we can deliver selected changesets between source and target. Thanks.

This is the API I am aware of, from my blog post. Maybe start there?

System.out.println("Comparing Change Sets...");
    IChangeHistorySyncReport changeSetSync = repoWorkspace.compareTo(
            targetStream,
            WorkspaceComparisonFlags.CHANGE_SET_COMPARISON_ONLY,
            Collections.EMPTY_LIST, monitor);
    System.out.println("Deliver Change Sets...");
    repoWorkspace.deliver(targetStream, changeSetSync,
                Collections.EMPTY_LIST,
                changeSetSync.outgoingChangeSets(component), monitor);
