Invoices

An invoice payable in the chosen coin and network.

How it works

You create an invoice with a fiat amount: amount has at most two decimals and currency is its currency (USD by default).
The service converts the amount into the chosen cryptocurrency at the current rate.
The response keeps the original values in sourceAmount, sourceCurrency and sourceRate, while amount holds the crypto amount to pay.
After the payment, Atomic Pay tracks the transaction and waits for the required confirmations.
Each invoice state change triggers a webhook. You can also check the state via GET /invoices/{invoiceId}.

remainingAmount = max(0, amount - confirmedAmount)
overpaidAmount = max(0, confirmedAmount - amount)
If confirmed and pending amounts together cover the invoice, the status may be confirming.
