I used to be the VP of Engineering at Simple. We always wanted to release an API but weren't able to. They're working on a bunch of great stuff over there, but I hope they do release one someday.
As someone who uses Simple every day, I'd kill for an API. Would be cool to do some analytics on my spending on top of what they already provide.
Why weren't they able to? Lack of time, demand, security, did it wrong and had to start over?
I can no longer speak for them, but while I was there we were entirely focused on getting our core consumer online banking product right. We did not want to launch an API without properly supporting the community, and we didn't want to distract ourselves from executing on the core product. There were other complexities but it's not appropriate for me to say any more.
there are api endpoints, just not documented, right?
