Thanks Riaan for the answer,
very helpful links, but i still need to understand one thing, the gateway i’m using is Form-based so i need to call a URL where i send some required data (merchant ID, security hashs, …) along with the total amount to be paid this would open a new tab in the browser than it should get me back to woo where i should verify the payment so it’s pretty like Paypal
but with paypal there’s an SDK to use
if i don’t have an SDK how do i invoke the URL call and when i get back using the callback url i’m being redirected to a thank you page how i should verify the payment
thanks in advance
