Looking for a payment processor for one of my websites.

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

Should have the opportunity to put BUTTON on my site – like Paypal,

So that buyers can click the button,

Make payment for my product –

And go to the download link.

And the payment is done to me immediately.

Do not look for Paypal.

Does anyone know about it?

Thanks and greetings.
