Why It Happens
CoinPayments and Coinbase Commerce lock the FX rate for a short window (usually around 60 minutes). Payments that land on-chain after the timer can’t be auto-matched to your invoice without manual review.
What to Do
1
Collect the details
Save the transaction hash (TXID) and any order reference the gateway displayed.
2
Share with Support
Contact us via messenger or email with the invoice number, TXID, timestamp, and amount sent.
3
Wait for processor review
We liaise with the gateway to apply the payment or trigger a refund, then confirm the outcome.
