Are the hidden values unique to each paypal account
I have built the free tools paypal store, and have used my own email address to test with. I am now about to add the live email address to be used in the PayPal add to cart and saw the following:
<input type="hidden" name="business" value="sales@website.com" />
...
<input type="hidden" name="receiver_email" value="sales@website.com" />
<input type="hidden" name="mrb" value="R-3ZY1234B9876543X" />
<input type="hidden" name="pal" value="ABCDEFGHIJK9" />
The last two listed... "mrb" and "pal"... are they unique to each email address or PayPal account? If they are unique, how do I find these for the desired account?
Also, what is the difference between "business" and "receiver_email"? They are both the same value.
Thanks
