Hi everyone... this is my first post - so please bare with me.
I already have an API Certificate that I use on another site and would like to use PayPal Express and Pro on a new site also.
My problem is that I can find the API USERNAME and PASSWORD but not the SIGNATURE that is required for setting up PayPal Express... Does anyone know how and where to find the SIGNATURE?????
Thanks in advance - Cadi1999
