Hyperswitch is an open-source payments switch from Juspay that you can run on your own Linux server. This guide covers setting it up with Docker, checking the ports the stack opens, running a curl health check, and processing a test payment to make sure everything is working.
Most payment integrations start out simple. You connect to one payment processor, add its SDK, and configure a few API keys.
But things can quickly become more complicated. You might need a second processor because the first one declines cards from a particular country, then you may want to add payment retries. Over time, the payment logic can end up scattered across multiple services and become difficult to manage.
