Testing & Troubleshooting
Test checklist
- A test payment in sandbox mode is confirmed.
- A successful payment marks the order as paid.
- A failed payment leaves the order pending.
- A duplicate confirmation does not double-credit.
Common problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Order stays pending | Confirmation URL not reachable | Check the public URL and firewall |
| Confirmation rejected | Wrong IPN secret | Re-enter the secret |
| Amount mismatch | Exchange-rate change | Confirm the coin settings |
| No crypto option at checkout | Gateway not enabled | Enable it in checkout settings |
Refunds
Refunds are manual and handled through your CoinPayments account. Always confirm with the buyer before sending crypto back.
