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.

Types of invoices

  • With no sum and no time indication — this type of invoice has no indication of sum and expiration time.

  • With indication of sum and time — this type of invoice contains information about the sum and time of the operation. A receiver of such invoice can recalculate the sum of the invoice according to the current rates by clicking the Recalculate button.
