Hello all,
I have tried to get mu user timeline status watching a video.I put the URL to get the output.But it doesn’t work.I really need it as I want to implement it in a Wordpress plugin.
Here is my url:

Showing an error that “{“errors”:[{“message”:“Sorry, that page does not exist”,“code”:34}]}”.

Is there any alternative way to get?

So please help me out.
