... find out until you're debugging why a real user got a wrong answer. Ended up hand-building the connectors that really matter (the ones where getting the semantics wrong costs someone money) and using MCP purely for the longtail where "mostly works" is good enough. Anyone else gone deep on MCP servers? Curious if others found the same gap between the demo and production, or if I just hit unlucky servers. Comment from Haider Murtaza(@haider_murtaza3 ...

... channels worked very well, but the funniest one was one of our Reddit posts. We got zero comments or upvotes, but thanks to the tracking link we were able to write this comment: And get some feedback back The longtail effect Another perk of using LnkFlow is that we can see how the link performs over time. Even on non-launch days, I can see clicks, and over the

... When we launched, the pitch was simple: one platform, any processor, no lock-in. We had no idea what we'd signed up for. 70+ processors later (Stripe, Adyen, Razorpay, PayPal, Checkout.com , Worldpay, Mollie, plus a longtail across Europe and North America), five lessons: 1. "Declined" means something different to every processor Numeric codes. String codes. Both, contradicting each other. 200 OK with failure buried in the body. Normalising this took us nearly a year. Still the most thankless ... ... optimisation. It's a liability. Stored PII compounds risk nonlinearly. We rebuilt the connector layer so nothing persists beyond a single request. Painful. Worth it. 5. Regional processors are a different game Stripe and Adyen have decent docs. The

... backlog, and then... you wait. Sometimes for months. Sometimes it never comes. That's been one of the most consistent frustrations we've heard - and honestly, one we've felt ourselves. Our native library covers 130+ integrations, but the longtail of tools people actually use is endless. No matter how fast we build, we can't keep up with every API out there. So we built a different answer entirely. Custom Integrations - launching on Product Hunt May 6 - lets ...
