Channel-Based Configuration & Tabs Overview

The Channel Selector at the top of the PayU Money setup page allows configuring payment settings for each platform. This section explains all tabs (General, Products, Brands, Categories, Customers, Customer Groups, Channel Groups) together for clarity.

Available Channels

All channels created in the O2VEND store can be configured.
Examples of channels include:
- Online Store
- Android App
- iOS App
- POS
- Other custom channels

Each channel maintains its own configuration, allowing tailored settings such as Merchant Key, Salt Key, and rule-based availability for all tabs.

How Channel Configuration Works

Settings for a specific channel apply exclusively to that channel, ensuring precise control and flexibility.
Positive usage examples:
- Enable PayU Money only for the Online Store while keeping mobile apps optimized for other payment options.
- Use separate Merchant Keys for each channel when required for maximum security and customization.
