I apologize for the possible simplicity of this post but I am not a developer. I was asked to gather some information.
My company produces a web based SaaS product. Our customers can invoice their customers and enter payments in our system. Currently if our customer accepts PayPal they would manually have to enter the payment in to our product. Does PayPal have an API that would allow our customers to receive money to THEIR PayPal business accounts from their customers and have that update our software?
If yes can you point me in the right direction as far as what API that would be?
