I am looking for a payment processor, for one of my websites.

I should have the ability to place BUTTON on my site, like Paypal,

So buyers can click on the button,

Make the payment for my product –

And go to the download link.

And the payment is made to me immediately.
SEMrush

I'm not looking for paypal.

Does anyone know of any?

Thanks and regards.
