title: How do I get an API Username, Password, & signature from PayPal to use in a third party plugin
body: <p>I ended up here from paypal because I can only find programming info to add apps to paypal or something to that effect. I am trying to get info from paypal to plug into WP-Client so I can invoice clients through my website via Paypal. Every time I ask this question on Paypals site they send me to the developers reference which I don't understand nor need. The programming is done, I just want access to my paypal account through my plugin which asks for the API username, Password, and Signature.</p>
