Hey there! We've shipped some quality-of-life improvements to make debugging API issues a breeze — or, if not a breeze, at least incrementally more pleasant.

First up, we've polished the API requests dashboard with a bunch of nice grace notes, including deep links into the relevant emails and subscribers associated with each request.

But here's the real treat: we've launched a comprehensive (and overdue) API error codes reference! If you've ever scratched your head wondering what email_invalid or subscriber_already_exists actually means (and more importantly, how to fix it), this new documentation page (and the concomitant sections at the end of every API endpoint) has you covered.

Small touches like these might not be flashy, but they make working with Buttondown's API that much smoother. Happy debugging!
