Linnworks can keep track of payment methods that were used for orders on the marketplace and orders in Linnworks can automatically display the payment method that was selected on the channel. In order to set it up, you need to configure the payment method mapping for each sales channel.
1. First, you need to create payment methods in the Edit Order screen in Linnworks.
2. Then you can map the Linnworks payment method to the channel payment method. Depending on the channel, you may also need to create those payment methods on the channel itself first.
For more detailed information on payment method mapping please refer to this documentation.
