Managing requests on GitHub
See Connecting a GitHub repository for how to connect one in the first place. Once it's connected, the delivery style you chose for it decides what shipping a request against it actually does.
Direct push
CustomerShip pushes the finished change straight to your target branch — there's no pull request and no review step. The request's detail view links to the branch and commit once it lands. This style is only available on GitHub.
Create and track PR
CustomerShip opens a pull request against your target branch and keeps tracking it: its detail view shows reviews as they're submitted, plus every comment (line comments and general PR comments alike). It never merges the PR for you — that's always your call, from GitHub itself.
Requesting a re-work
On a Basic or Pro plan, the delivered request's detail view lets you select specific comments and queue a bounded re-work pass against just those. The same thing can also be triggered from GitHub directly, without opening the dashboard at all: comment /rework followed by instructions on the pull request itself. Only a comment from the repository's owner, a member, or a collaborator is honored — a comment from anyone else (for example, an outside contributor) is ignored.
