Confused with PayPal API

Hi, I’ve been using Woocommerce on numerous sites and have had no trouble. However, today I installed it new on another site and went to hook up the PayPal API but it’s different than it once was. Now, instead of giving two options as noted in the tutorial, now you have 3 options:

1. Pre-built payment solution
   You’re using a third-party e-commerce solution, like Magento or Shopify, for shopping carts and online stores where the PayPal payment processor is built in.

• Grant API permission
• Add or edit API permissions

• PayPal Checkout SDK integration
  You or your developer integrated the Braintree v.zero SDK that allow you to accept payments via Paypal.

  Request SDK Credentials

• NVP/SOAP API integration
  You or your developer integrated NVP/SOAP (or “Classic”) APIs that allow you to accept payments via PayPal.

  View API Signature

Assuming the first is the one to choose, I click “Grant API Permission.” It then asks for:

Add New Third Party Permissions

Manage permission given to a third-party application to access specific information in your account and take actions on your behalf.

For more information about the permissions you are granting, see Third Party Permissions.

Third Party Permission Username [data field]

I’ve tried typing in Woocommerce, along with an array of other entries, but nothing seems to work.

How do I get the API Username, API Password, & API Signature?
