BingAds upload offlineconversion

Question

HI,

I am following this sample code from site
https://learn.microsoft.com/en-us/advertising/guides/code-example-offline-conversions?view=bingads-13

to upload offline conversion goal using Campaign Management service.

I have a doubt, with conversion goal. To upload offline conversion do we need to set up conversion goal , is it mandatory ?

And only for testing purpose : is it possible test it without Authentication ??
