PayPal API Signature

[cadi1999]

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

Zen Cart does not work with API Certificates. It only works with the API Signature offered by PayPal.
As far as I can tell, PayPal only lets you use one method at a time. So, to switch to using a Signature, you'll have to cancel your Certificate and have them generate the Signature.
You might try contacting PayPal for details on how to have both available at the same time.
