About this Gig

Payments done the safe way! Server side receipt validation so your revenue is enforced on the server, not trusted from the client.

No double credits, no lost purchases, no silent revenue leaks!


I've shipped this across Apple, Google Play, Steam, Stripe and more on a live platform with a credit economy and VIP subscriptions - which means I've already met the edge cases that cost you money - replayed receipts, refund abuse, subscription renewals arriving out of order, sandbox receipts in production.


What you get:

  • Server side validation endpoints for your store(s)
  • Idempotent granting - a purchase can never be credited twice or lost
  • Subscription status handling, restore flows, and refunds
  • Webhook handling for renewals and cancellations
  • Entitlement logic - credits, wallets, tiers - whatever your product uses
  • Client wiring (Unity, mobile, or web) and tests to validate


Any stack on your side - message me before ordering and tell me which stores and what you sell!
