convertkit-ruby VS Octokit

I would then pass this email address as a second argument to my Ruby script, and then use the ConvertKit API via the convertkit-ruby gem to see if there's an existing entry for that email address, and that the custom field that indicates they purchased Ultimate is filled in.

After extracting the GitHub username from the Paddle payload, I would use the octokit gem to add the customer as a read-only collaborator to the repo. Something like this:

Some important things in this reflex. One, since our partial requires a form object, we use ActionView::Helpers::FormBuilder to create a form for a user building an initial repository. Since it requires a view_context, we leverage a delegate to access it from the controller. Two, the Octokit client requires a user authentication token, so we add delegate to the connection so we can access the current_user. Three, rather than triggering a full page morph, we instead can use a selector morph so it only updates the div with id #repositories.

Here's an example of doing that on octokit gem: https://github.com/octokit/octokit.rb#debugging
