Hi:

If I have correctly understood you have to go to paypal. Go to Profile
Under "my Account" go to API access.
Choose to get Api credential (signature) you will get a Username, Password and a signature. All of that have to be copied on your Express Checkout Payment Module (Zen Cart)

Copy and paste the api credentials on your Express Checkout payment module.
You have to edit this one. (Configuration--->Payment Modules--->Express Checkout.



I am not an expert. But hope this will help you.
