**Yes, it’s only possible to specify branch names (more specifically, valid remote refs).**

I’ve tried supplying a SHA-1 instead as `branch` and [a build was created](https://travis-ci.org/native-api/test_travis/jobs/571856078). But the supplied name is being passed to `git clone --branch` and the cloning thus failed.

**Nothing prevents you from creating a topic branch at any commit though.**
