Paypal Standard Setup

Hello,

I’m attempting to setup my payment gateway with paypal standard. I’ve read through the documentation for both WP invoicing and pricing manager (both installed on my site as well as GD). I’m finding it hard to locate basic instructions for set up, other than a screen shot of the settings. Is there a place to link an API? How does it connect to paypal? I see a place for a paypal email but I cant seem to find that email in my paypal business account. Do I need to do something in my paypal developer section?

Sorry if this is basic stuff. This is the first time I’ve attempted to link paypal to an ecommerce platform. Normally I just use paypal for invoicing clients for courses and consulting. I understand the concepts of APIs and webhooks (somewhat) and I can’t seem to find anything to guide me regarding setting those up for these 2 plugins. Am I over complicating this? Is it really as simple as having a paypal email and if so, where can I find that info?

Thank you,

Justin
