This is distributed transaction problem, and there are multiple ways to solve it with the simple one being callback (webhook) with timeout. Put debit in a pending state, wait for response from API call, if successful complete transaction else fail and log it.

On the Calbank app, a transaction can fail and when you try again you realize the failed one went through resulting in multiple transactions. I'm curious how they are not catching that. Backend guys, there should be a way to prevent this right? How do you handle such cases?

People who maintain open source software deserve to have normal lives. E.g., enough money to live reasonably, enough time to have families, and a work life free from abuse. It doesn't make sense that we sacrifice these things so companies can save money on their software stacks.
