"Bad Authentication data" error when using the GET Rest API generated by automatic generator



I am first time using twitter api, I am trying to call at-least one API for a POC but till now I am finding no luck. I am using the url generated by “See OAuth signature for the request”, this the url generated by the request: (I have removed keys for security purpose)


But if I ping, I get this error:

“Bad Authentication data”

I am 100% sure auth data is correct, as I copied and didn’t typed. Any help here?
