Hi, I am developing a web application where I need to allow some vendors using my application sell their services. I would like to integrate my app with PayPal express checkout. I ran into an issue where using express checkout requires the seller Client-ID. In my case I am only allowed to get the sellers PayPal email address and not their PayPal Client-ID. How can I use their email instead of Client-ID to use PayPal express checkout? Appreciate your help in advance Kazem
