Hi,

I am trying to configure the PayPal Advanced Payments>> Merchant Sandbox Account into my Magento 2 website.

But, facing some of the following errors:

1) "Invalid Vendor ID"

So, Kindly provide some proper configuration instructions for the same, like (What to enter in the Vendor ID/User/Partner?)
