Anyone using Postman for API calls?

[Stevenjwilliams83]

I am new to this API stuff and I am trying to use postman to get just basic objects out of my palo. Just something as simple as "https://192.168.81.50/restapi/9.0/Objects/Addresses" the return I get it cannot get any response. I setup my api key in authentication portion of postman and selected to be added to header and I just cant get anything to work so any help would be great.

@Stevenjwilliams83  hope this helps you. make sure the following params are setup, also make sure PostMan settings to allow SSL certificate verification is off File> Settings>General by default this is enable if your do not have a valid SSL cert it will not allow you to connect. 

Side note: 

location = either vsys or panorama-pushed ( depending if you are looking for objects push from panorama or the local firewall)

vsys = vsys1 ( single vsys )

Do you have the API key in your headers in Postman? Using X-PAN-KEY? I have set my key with a variable, but you could also type it in directly to the "value" box if you wish. This is after you have generated a valid PAN-OS API key which is still within valid lifetime?
