Workshop title

Resolving missed connections


Connectivity is the plumbing that enables everything we’re trying to do. Whether you’re connecting directly to a banking core, or to a fintech provider’s API, or something in between - you’re dependent on the stability of your upstream providers to serve your consumers.

Want to give users the ability to move money? You need to verify their account information - by connecting to a verification provider or to the account-holding institution directly.

Building tools to help users manage their finances? You need data from every financial institution they use.

When these connections break, are you out of luck? In this workshop, you will build solutions to some common connectivity problems that give your users the best possible experience even when the plumbing fails.


  • Participants create a github account if they don’t already have one
  • Participants clone a github/mx-enabled repo specific to this workshop
  • Instruction describing common problems (API is down, user credentials are incorrect, user has insufficient privileges, no connection available for the selected institution).
  • Participants run the app they cloned in Step 2. The baseline app fails user expectations randomly for a few underlying reasons. Participants write code (maybe we can make this easier? Not sure) to handle the underlying failures and improve the user experience.
