eCart 4.52 checkout wizard and Payments Pro settings

I've been having trouble getting eCart to work properly. I've deleted all eCart folders and related pages and am starting over. In the wizard, Step 1 of 2 asks for Merchant Account User Name, Merchant Account Password and Merchant Account Signature. I believe I got this correct -- the info was in PayPal Option 1 setup paypal API credentials and permissions.

As I continue to Step 2 of 2 -- the wizard asks for PayPal Express account info. Is this information the same as the merchant account info? It asks for user name, password and signature/vendor. If it's different, I know what my paypal user name and password are, but what is a PayPal signature/vendor?

So, should the info entered be the SAME for both steps?

Help. Thanks in advance.

If you look at this pic taken from your documentation, you'll see why I'm so confused about this.

Your demo shows an email address for the merchant account user name, and password for merchant account password. But when you get your credentials from PayPal, it says API user name, API password, and signature.

So what I need to know is specifically, in the eCart 4.5 wizard, do I used my regular paypal user name and password (that I log in with all the time) in the wizard or do I use the API user name and password associated with the paypal signature. I think the word "merchant account" throws me off, as I don't really know what it means. If my "merchant account" user name and password are the SAME as my regular paypal user name and password, it might make sense. But using "merchant" makes me think this is a new or different user name and password.

I still need to know if the same info is entered in step 1 of 2 of the wizard and step 2 of 2. Thanks.

Is the paypal API user name or API password used at any time of step 1 or 2 of the eCart wizard?

What payment option are you choosing to work with inside of the wizard? If you choose Payments Pro you should only be entering your PayPal API username, API password, and API signature that you get in the profile area of your account. With Payments Pro there is no need to use the PayPal login details, only the API info.

Hi Eric,

Thanks for responding, though I did get it after a few hours of trying the various options.

For those of you using paypal pro and express checkout -- ALL the settings you'll need are in the PayPal API credentials and permissions section. I sure wish it simply said this somewhere, it would have saved me days of frustration.

I do appreciate your help.
