@roalnd-baldin It seems to work with curl in command if the data-raw is rewritten like so:

–data-raw “{
\“resourceValue\”: \“48656c6c6f20446576696365\”
}”

In command we get a nice “msg”:“Accepted”,“code”:1002 response but in Postman it does not work. And with the registration to https://{{base_url}}/m2m/applications/registration this was not an issue.
