Paysera is not supported for Madagascar, it's only for EU countries - I have not received an reply from 2checkout & Paymentwall yet, it's been a while I would to know if I have other options available .
If I find another payment gateway not listed on your list is it possible to integrate it to my store?
Is there any chance a shopify developer can integrate the credit card option to my store so my customer can pay by card ? I really need help because I'm not able to use the others payment gateway
These are the payment options available for Madagascar
