How can I implement UPI payments in my Flutter app without relying on third-party gateways?

I’m looking to integrate UPI payment functionality directly into my Flutter project without the involvement of intermediary services that charge fees. I realize that many common approaches depend on third-party payment platforms, yet I’m exploring if there’s an alternative route to bypass these middleware solutions. Could someone suggest methods or techniques that allow for a direct UPI integration within a Flutter environment?

hey u can deep link to upi apps directly, invoking intents without device fees. it needs some manual native code intergration and error checks, but it does bypass third-party fees. best of luck tryin out!

In my experience, another approach involves using a hybrid method where a lightweight backend handles the UPI transaction lifecycle. This is particularly beneficial if the direct UPI APIs from banks are cumbersome to integrate with due to regulatory requirements. By offloading certain functions to a server, you can maintain control over the payment flow without fully surrendering to third-party platforms. This method requires a thorough understanding of both client and server implementations, careful error handling, and compliance with banking protocols. Although this setup adds complexity, it offers greater flexibility and control over device-specific integrations in Flutter.

Hey, I’ve been tinkering with this space quite a bit and was wondering – have you checked out integrating directly with the NPCI provided APIs? I came across some discussions mentioning that getting official documentation straight from the source might help clarify a lot of the regulatory and technical requirements. From what I understand, though it’s a bit of a labyrinth with banks and compliance, directly speaking with a few banks could potentially clear things up. It might also be worth looking into customized Flutter plugins that some developers have made open source – even if they require a bit of tweaking to suit your specific app. What do you think, have you already explored any resources from NPCI or tried contacting banks directly? Would love to hear more about your approach and any hurdles you’ve encountered so far!
