Hi there @annabella03!
Don here from Shopify. :)
It would only be possible to use the payment gateways which have been made available for integration in your region currently.
You can see your options in this regard in your settings > payments menu in your admin, or if you can confirm here where your store is based we can provide a link to a full list you can browse.
Was there something, in particular, you were looking for from a payment gateway there?
