Payment method in Mollie not supported in Shopify?

[StudentLaptops]

Hi all,

I'm trying to use eco vouchers from Mollie in Shopify but there does not seem to be any integration yet. (I can't find it in Shopify's "add payment method" list. Is there anyone who has managed to make it work in their webshop? If not, Mollie lists a way to directly speak to their API but I'm unsure how to go about it exactly to implement it in my webshop. Can anyone provide any advice?

Thanks!
