hope this helps.
ps: I added the invite user email to the program for you since I did not have it in there.

Thanks also @girish - This works for me also.

Just in passing:

• I initially had the same powershell annoyance as @prusaman here: https://forum.cloudron.io/post/62509 - Not sure what this is all about, but linux's just fine.
• the curl sample is missing an end quote here: https://docs.cloudron.io/api.html#tag/Users/operation/addUser

curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $CLOUDRON_TOKEN" "https://$CLOUDRON_DOMAIN/api/v1/users" --data '{"username":"Example","email":"example@example.com","password":"insertYourPassword","displayName":"Example", "role":"user","fallbackEmail":"fallback@test.com"}

Thanks again

You can script whatever your requirements are based on the API. The users API is now online at https://docs.cloudron.io/api.html#tag/Users
