Conversions

Payment / conversion lifecycle — request, accept, confirm, cancel, status and history

Request a conversion (create payment order)

post

/confirm_conversion/request

Creates a new payment order. The code returned is used in all subsequent calls (accept, confirm, cancel, status).

Either merchantIdentifier (POS/collector) or websiteUrl (e-commerce) must be provided — at least one is required.

If websiteUrl is set, sessionId is also required.

If alias is set, the order is treated as a payment link (valid for 1 month by default). Without an alias, the order expires after ~5 minutes.

The webhook at webhookUrl will receive a POST request with the full order status on each change.
