Where do I get the Signature, required for PayPal
The Signature must be generated using the API Access link on your PayPal Profile. A unique API username, API Password and Signature will be generated, or if you already use some type of web based shopping cart, you can view the current API username, API password and Signature. Note that the username and password is not the same as the information you use to login to paypal's web site. The signature is quite long, so please be careful when entering it into your phone.
