Friction is the kind of thing we're constantly exploring how to remove.

We want to make sure that you have all the information you need, and that you can find things quickly. With that in mind, we've decided to bring all of our API Reference documentation into the app.

For example, when you navigate to Domains, you can see all of the available methods related to domains right there without having to open a new tab.

The same goes for other resources like Emails and API Keys.

We hope this makes your life easier and that you can find what you need faster.
