Completing online orders at POS with custom payment

Retail & Point of Sale

I’m trying to collect payment for an online order using the custom payment button on the POS app. However, whenever I try it, I get the screen which says it will “Order will be marked as paid. Custom payments are not processed by Shopify.” and when I click “Mark as Paid”, the screen starts to process and then I get

“Payment declined”
There was an issue with Shopify and the payment couldn’t be processed"

Why is this happening? I though custom payment is not being processed by Shopify. Why is the payment being declined?

If I select a different payment method (ie Cash) it works fine and allows me to enter the amount paid and marks as paid.

Have I forgotten to set up something? Why is Custom Payment not working?

I can checkout a POS order using the custom payment without a problem. The problem only happens when I try to complete an online order using the POS app.

I"m going to answer my own question. Talked with Shopify Retail Support. This functionality (finishing up online orders in store using custom payment) is not supported by Shopify POS (or POS Pro).

I’ve found an App called Sales Terminal POS which WILL allow me to edit online orders and use custom payment method.

It ridiculous that Shopify advertises the possibility to create manual payment methods online and offer in-store pickup, but doesn’t offer a clean way to process orders in-store for online orders using their own Shopify POS.
