Question

I have successfully set the attributes of my Facebook Page using the Graph API following the documentation for this functionality at this link. For example I am able to set the general_info field by sending a post body with the following:

access_token=<MY_PAGE_ACCESS_TOKEN>&general_info=This+is+some+general+info.

But now I would like to remove the general_info. I assumed that sending a post body with an empty string would remove it

access_token=<MY_PAGE_ACCESS_TOKEN>&general_info=

but I get back

{
    "error":{
        "message":"(#100) Parameters do not match any fields that can be updated",
        "type":"OAuthException",
        "code":100
    }
}

I have also tried:

access_token=<MY_PAGE_ACCESS_TOKEN>&general_info=None

and

access_token=<MY_PAGE_ACCESS_TOKEN>&general_info=null

But these just set my General Info to ‘None’ and ‘null’. I also tried sending JSON content so that the null would be unambiguous, but the API just seemed to respond as if it couldn’t handle JSON at all.

My other thought was that maybe it requires an HTTP DELETE request, but as far as I can tell the Graph API doesn’t return any ids for these properties that could be used for the DELETE request.

Has anyone done this before?

Try sending a space.

access_token=<MY_PAGE_ACCESS_TOKEN>&general_info=+

That might work
