Got HTTP response code 403 when using 3Scale API through threescalesetup java project

[osamagotji]

After running the following commands.

mvn exec:java -Dexec.mainClass=threescalesetup.SetupApp -Dexec.args="<myDomain> <myAccessToken> financeapidemo financeapidemo true productiondemo 'Finance API Demo for Agile Integration'"

I got the following response.

I tried to debug the java project and found that it sends HTTP POST request to URL "https://<MyDomain>-admin.3scale.net/admin/api/services.json" with "Content-Type: application/x-www-form-urlencoded"

I also tried to send this POST request manually and got HTTP code 403 as well.
Not sure that this is because 3scale API had been changed or I did something wrong.

Is there any idea about this error ?
