Does this mean the PayPal API Signature????
Could you please clarify more on your instructions? This is the PayPal API Signature that one has to obtain from PayPal correct? There is absolutely no explanation about this anywhere. The letters API are crucial if that's what it means by signature. I was thinking that it might be what the users might see as who the payment comes from.
I'm trying to figure out why my store isn't working and thing this signature might be the problem - only I wasn't sure what that meant.
And where and how is this information transmitted to PayPal?
