it happened to me too.
On a fresh project import IAP > copy this folder > paste it in your working project.
I did it inside finder/explorer window and it worked.
Hopefully it’ll work in your case as well.

This worked for me > Thanks much!
Thanks, worked for me too
Thanks, worked for me too
Is there another solution? It did it again and now i have to create a new projectID in order to import the IAP ?
If you imported unity IAP to your project, plz enter to Plugins - UnityPurchasing folder. You must see a unity asset file,
import it into your project. it will resolve your problem.
Thanks~
There seems to be major bugs with the services window at the moment.
We had some issues with our authentication server, which affected the Services window.
The issues on the server should be resolved now. What issues do you see with the services window?
Well apart from this issue, lots of people seem to be having issues with Ads, and the usual workarounds don’t seem be working.
I seem to have the same issue as the last post (37) here: https://forum.unity3d.com/threads/bug-issue-in-unity-5-5-1-when-using-ads-from-services-window-use-asset-package.453084/#post-2960817 although I haven’t tried the suggested steps yet.
Thanks so much!
In order to help us resolve this issue, I am closing this thread. If you come across the problem with undefined Purchasing classes, please create a new post and provide as many details as possible. The information requested here is very helpful:
In particular, we would like to know:
- Unity version
- IAP plugin version
- If you updated your plugin or unity version before this error occured
