SALE

This page describes the ExpressPay iOS SDK SALE Adapter.

Overview

Payment Platform supports two main operation type: Single Message System (SMS) and Dual Message System (DMS).

• SMS is represented by SALE transaction. It is used for authorization and capture at a time. This operation is commonly used for immediate payments.
• DMS is represented by AUTH and CAPTURE transactions. AUTH is used for authorization only, without capture. This operation used to hold the funds on card account (for example to check card validity).

SALE request is used to make both SALE and AUTH transactions.

If you want to make AUTH transaction, you need to use parameter auth with value Y.

If you want to send a payment for the specific sub-account (channel), you need to use channel_id, that specified in your Payment Platform account settings.
