Hello Guy,

I am using trial version of SalerForce. I am trying to call the Force Rest API but I am getting response like this:

    "message": "The REST API is not enabled for this Organization.",

I got few soultions. It was saying that I need to check API enable check box in "Manage User -> User -> System Administraiton -> Administrative Permission" .But  I found it is checked. . 

I am still gettting same error . 
Please help me.

Thanks and Regards,
