Show Payment Hint

This guide is for the deprecated Flex.API. If you are starting with a new integration, please refer to the Guide for the secuconnect API: Link

You can pass a hint to explain the payment. It consists of lines with text pairs, each aligned to the left and to the right, like on a cash receipt. You can also modify the headline above it.

Example request:

POST /payment/init HTTP/1.1
Content-Type: application/json; charset=utf-8;
Accept: application/json
Accept-Charset: utf-8
