Haha. Hopefully it wasn't too painful figuring out that you had to do this. RuboCop as a whole is relatively new. We rolled through at one point and killed a bunch of the RuboCop TODOs, but all the slightly harder ones are still left.

[brandur-stripe]

LGTM.

@jkakar-stripe Here and with other PRs, would you mind just rebasing so that we have one clean commit to bring in? We are trying to do a little bit better on commit hygiene in the open-source repos these days :$

[jkakar-stripe]

@brandur Thanks! I've rebased all the pull requests down to a single commit. Maybe we should make Squash and merge the only option available on these repositories to avoid the need to manual rebasing?

Could do. I kind of like the manual rebase it tends to produce final commit messages that don't include all the messages from various throwaway commits in them. Definitely a personal preference thing though.

[jkakar-stripe]

@brandur Yeah, that's a good point. I did take the rebase opportunity to create a clean commit message for each branch.

Nice, and looks great. Thanks!

What are topups? 🤔 They don't appear in the docs yet, although there are some events related to them documented.

[ob-stripe]

@timrogers It's an upcoming feature that's not documented yet.
