I need to create questions using Graph Api where options are my app objects(webpages).
Example:
Question: Which program should I watch?
// http://www.example.com/programs/1
// http://www.example.com/programs/2
The example of documentation page only show creating option with text.
Edit:
Is impossible to add custom objects to questions through the Graph Api?
That isn't a supported use-case of the Questions API - you can use URLs as the text of the Question's options, but they won't be linked when displayed on Facebook.
