Invoices

Invoices are bills with indication of a sum and payment address which you render to payers. The invoice currency may differ from the wallet currency — a payer can specify any currency for the invoice.

Key points

  • The system accepts payments in crypto currency and allows you to enroll and withdraw funds in fiat currency.

  • Each transaction requires a certain number of confirmations in the blockchain.

  • The processing speed of a transaction in the blockchain depends on the blockchain fee amount.

  • Information about new transfers associated with an invoice can be sent to your system via a callback.

  • Each transaction can be assigned a special identifier by which the transaction can be tracked in your system.

  • It is possible to generate a payment page in order to send payment details to your payers.

  • It is possible to set time limits to specify the expiration time for the invoice as well as payment limits to hedge possible payment amount variations due to rate changes.

Types of invoices
