Paypal API confusion

I’m trying to connect Paypal to a site and am confused about something. See the attached screen shots, one from Paypal and one from Backlight. Paypal gives me Sandbox Account, Client ID, and Secret. Backlight asks for Username, Password, and Signature. Do they match up, even if the words don’t?

Hi @hulsebos58, have you tried following the documentation we have here?

I have just taken a look and the instructions should get you to a screen that does actually lead to the fields that Backlight is expecting (Username, Password, Signature).
