Setting Paypal eCart 4

During the Checkout Wizard, I entered PayPal. Then eCart generated a Username, Password, and Signature. I already have a PayPal business account. Do I use the info generated by eCart here or do I request my own API information from PayPal and then type over this auto generated info in eCart?

Before running the checkout wizard, you should b=have signed up for the API Credentials and entered them in the checkout wizard.

If you entered dummy API Credentials when running the wizard, you will need update the pages that are created to replace the dummy credentials with the real ones.

I did not enter any information in those fields. They appeared. I thought that ecart generated that info: User, Password, SIgnature. I did not type this stuff. They were very long and would have been hard to even retype. How could info be there if I did not type it?

A couple of years ago, I set up a "Pay Invoice" page on our website using paypal. It is a no-nonsense page that is simply a form that lets the person type in the invoice number and the total amount they want to pay. One button takes them to paypal. I did not use the ecart. Could the ecart have found this info in Dreamweaver and entered it for me?

Yes, that could be. at some point you must have entered the info somewhere in DW for it to auto populate in he checkout wizard.
