Error #1. User authentication failed.

I’ve reviewed the other articles on Error #1. User authentication failed, and as a result, I changed to a new PayPal account. Had to go through the whole underwriting process etc. even though I already had an older version of the website payments pro with the recurring billing.

Now, here I am with my new PayPal account and the I’m getting the same Error #1. User authentication failed.

I’m not using sandbox mode.

I’d appreciate some help. I can supply you with the error log file if you let me know which one you want to see.

The issue is resolved. I contacted PayPal Integration Support at 1-888-210-4901 and they told me that the information that I should put into my s2Member PayFlow Account Details comes from my PayPal Manager login information at https://manager.paypal.com/

Here is how it corresponds with s2Member PayFlow fields:

API Username = Merchant Login
Password = Password
API Partner = PayPal
API Vendor = Merchant Login

Glad you solved it. Thanks for the update. :)

Hey,

I have configured PayFlow credentials -> “Dashboard -› s2Member® -› PayPal® Options -› PayFlow”. But still why do I get this error?
I believe, Payflow® API Username is PayPal® API Username and Your Payflow® API Password is PayPal® API Password. Payflow® API Partner is PayPal. Did I do that right or something went wrong? Please help

Sorry to hear you’re having problems.

I would first ensure that the account that you’re using is actually a PayPal Pro account using the PayFlow API. Depending on your account type, you may need to fill out s2Member’s default PayPal Account Details, or the default PayPal Acount details in conjunction with Payflow Account details.

Hi Bruce,

I have checked that.. Logged in paypal manager, and it says I have PayFlow SDK/API Access -> Live. I have called paypal for confirming the same, and found that my paypal pro account supports payflow.
Now, I have configured S2member Payflow account details like this:

API Username = Merchant Login
Password = Password
API Partner = PayPal
API Vendor = Merchant Login

But still no fix for the above error.

What else I have missed out?

Thanks for the follow-up. We are very sorry for the delay in response.

Your Merchant Login + Password are not required in these fields. You’re looking for your API Username here.
