Original Summary

Hey everyone, ​Building the backend for a new SaaS is always fun until you hit the payment integration phase. For my recent project (SecurePitch.cc), I decided to use Python/Flask and integrated Polar for handling subscriptions instead of the usual Stripe route. ​The biggest challenge founders face isn't just the API, but handling webhook events securely without dropping data. A quick tip: always use a dedicated asynchronous worker or a robust retry mechanism in your Flask routes to handle Polar webhooks. If your main thread blocks during a webhook receipt, you'll lose sync with your users' payment statuses. ​I see a lot of founders wasting weeks trying to figure out backend architecture and payment loops instead of focusing on marketing and getting users. ​If anyone here is stuck on their MVP, I run a technical agency called Coresync. We help founders bypass the technical hurdles by building complete, secure Python/Flask backends and handling all the payment/webhook logic. We do fast turnaround MVPs (around $350). ​Feel free to ask any technical questions below about Flask or Polar, or DM me if you want to collaborate!   submitted by   /u/FortuneIndependent19 [link]   [comments]
