Latest commits
When using the SDK to query for various types of resources, it's common to pass in an sha property to limit results to a specific commit on a given project branch. In addition to specifying an actual SHA hash, the latest commit can always be targeted by passing the string "latest".
For example, it's possible to fetch all files for the latest commit on the master branch of a project without knowing the actual commit hash:
client.files.list({
branchId: "master",
projectId: "b22d7d80-d198-11e8-9718-e3d50f1a1b38",
sha: "latest"
});
