Hi, I'll launch my ecommerce with amazon affiliate program soonly, I see sometimes website with built-in payment method directly on the website I already searched on google and BHW but no way to find informations about this technique... I have knowledge in development (PHP, JS ect...) and I would like to know if someone know how to do this ? Or a hint from where to start... Thank you by advance! Ps: Is it correct to say "soonly" in english ?
