Hello

Are you checking this on Personal Environment?

Also Did you checked the same at postman?
Is it working there?

Also have you given space between bearer and token.

Thanks

Hi Tousif 

Thanks for your prompt reply.

I am using corporate account, and in development environment.

It works in postman:

I do porovide space between Bearer and Value in the string.

Hi,

When you doing Test in Service studio, you need to add the Request headers in the Header and Authentication tab and enter the keys in the Test tab, then do the Test button. 

Hi,

You missed to add authorization token in header as @Puja Rani mentioned. 

My God, it works finally, I think my problem is that I placed the parameter in the Headers and Authentication section. Great thanks. Puja Rani you are the best.
