I will integrate Stripe, PayPal or USDT payments with webhooks into your site or app

I add online payments to your website, app or Telegram bot and make sure they are reliable. What you get: 1) Stripe, PayPal or USDT (BNB Chain) checkout wired to your site or app. 2) Webhooks with signature checks and safe repeat handling, so the same payment never credits twice. 3) Order status in your database and an e-mail or Telegram notice. 4) A short README and a test checklist. I run live payments in production (card, crypto and App Store purchases), so refunds, failed payments and duplicate callbacks are routine for me. Send me your stack and which payment method you need. Fixed price per integration, delivery in 2-3 days.
