Things to avoid when handling payments:
1. Never assume a successful API response means money actually moved. Always verify.
2. Never skip logging failed transactions. The day a user says “I paid and nothing happened”, that log is all you have.
3. Never rely on users to report failures. They won’t, they’ll just charge back and move on.
4. Never leave a PENDING transaction hanging without resolution logic. Pending is not a final state.
5. Never go live without a reconciliation job. Money isn’t something you eyeball and hope for the best.
Your payment system is only as trustworthy as how you handle failures.
