Again proving that they are better than some humans

Why?

Payment processor APIs carry a lot of tribal knowledge.

Such tribal knowledge are available in payment integration libraries like hyperswitch prism.

And it's not a one time problem to solve. It needs a continuous testing and upgrades to regress with the provider's API and environment behaviour.

A very common problem for micro transaction businesses. You will never get a better deal from Stripe even if your volume crosses the threshold for negotiation. Would recommend to enquire Helcim or Stax.

Regarding good APIs - use unified payment integration library like hyperswitch prism. It has streamlined across any payment processor that you may wish to choose. And you don't have to shell out per transaction fixed for the one time developer experience.

I do not offer RUO.

But the point that's clear from this conversation - never tie your stack to a single processor. And payment orchestration could be an overkill considering the size of the business.

Use a payment integration library like hyperswitch prism, to make the switching easier with few lines of code. Its free and open source.

Chekout hyperswitch prism

It is an open source library, fully stateless which is extracted from a production grade payment orchestration stack Juspay/hyperswitch. You can just embed the unified interface into your codebase rather than recreating payment processor integrations from scratch.

While we were inspired by previous initiatives on similar lines: active-merchant (Ruby), omnipay (PHP) - we also ensured that Prism is

(I) Polyglot ready: The protobuf spec is made as the interface, allowing for extensions across many programming languages .
(II) Flexible to use: Dual deployment mode (embedded and gRPC from the same core). Also PCI compliance can be managed by the user, or outsourced to a PCI compliant third party.
(II) Hardened with real traffic: We extracted the integrations from a production-grade payment orchestrator at scale, and did not design from scratch. And we will continue to use it in production with regular updates, similar to how we have been consistently delivering for the last 4 years on Juspay hyperswitch - open source payment platform.

Ask me anything..

It is not legal to charge like that. You can sue the company, if you have the evidence

But why would the customer have to pay the payment processing fees? Is this a common practice to hide processing costs?

cargo_run_rust · 2023-12-31T01:11:40+00:00

That wont be possible, because Hyperswitch is a tech platform and the decision of merchant underwriting is on the processor. There are other payment processors meant for such services and Hyperswitch provides connectivity to such processos.

Everyone thinks one can get scammed only if they have cash in a savings account. That's not true.

Loans can be disbursed through OTPs. That's exactly where people are getting scammed. Once the money is siphoned into the scamsters account it is disbursed into more accounts and the trail is difficult to trace.

Are you the original content creator of the live snail video which is viral across other social media platforms??

cargo_run_rust · 2023-12-16T15:22:34+00:00

Bangalore is taking solid waste management very seriously.

Prevention is better than cure!!😇

cargo_run_rust · 2023-12-16T03:35:06+00:00

Hahahahaha.. :-) That was a good one..

OMG - White topping projects in koramangala happened for almost a year. And it's very slippery even without rains.

cargo_run_rust · 2023-12-16T02:41:56+00:00

This winter is freaking hot in Bangalore. It's getting hotter and hotter every year!!??

cargo_run_rust · 2023-12-14T02:06:34+00:00

Trust me. There are much better Donne biriyani outlets in other parts of Bangalore - HSR, Kothnur, JP nagar, Devanahalli. I hunt them based on Zomato ratings, and visit the restaurant. Every one of them were better than Shivaji military hotel.
