I want develop some extensions for Mexican users to connect to the bank account (this idea could be implemented by developers of other countries), similar to Android applications such as Finerio and Fintonic, after to connect, the application download all last transactions (a synchronization option should be added).
To be different from other countries, my extensions will have the name: HSBC-MX, Santander-MX, Citibank-MX...

How can I develop an extension to MMEX?

I want that MMEX is the best financial app...

Thank you in advance.
