At the moment only in English. We've seen that most developers we work with are generally OK using English-based documentation to code. We might look to broaden that to Spanish and Portuguese down the line but it's not an immediate priority.
We are starting with the banks with most coverage - so think Davivienda, Bancolombia, Banco de Bogotá, etc. We'll be looking to have quite a few go live soon. Good point on 2FA/MFA. We have built our API so it can fully account for those in the connection flow. More info here --> https://developers.belvo.co/docs/handling-2-factor-authentic...
Did you have an issue when typing in your url? Do you recall what the error message was? We do have a url validation in that form that requires https:// Typing in www. will give you an error.
Our product / tech team is mostly based in Barcelona (early team at least) but we'll actively grow our tech team in Latam as well - mostly Mexico City. Happy to get connected to folks you might think would be a good fit. :)
Thanks! We don't yet support NuBank, but it's on the list for sure - both for Mexico (where it launched a month ago) and for Brazil (where we'll look to expand soon). We do plan on adding neobanks and other financial data sources to our API though. Although we typically work in a "data source agnostic" way, we also spend time building up relationships and looking to get directly connected via partnerships.
