Financial transaction flow

• Partner application creates a new order using POST /v1/orders.
• After an order is concluded and its financial information is available, the partner application can send this data using POST /finance/v1/financial-transactions.
• Public API sends an HTTP 202 representing that the data format was validated and that the financial transaction will be processed.

The financial transaction object has a "pending" property. While this property is sent with "true", the financial transaction can be overwritten (using the same endpoint) to fix or update any data.
