Can anyone show me a quick example of posting a checkin with javascript using FB.api('/me/checkins', 'post', etc?? Mine doesn't seem to work. Also does anyone know if this will take a date variable?
The me/checkins appears to be a read-only table (there's no permission to request to do a add). Per the documentation, you can add/remove comments on an existing check-in as well as add/remove a user's like of that check-in.
From the https://developers.facebook.com/docs/reference/api/permissions/
user_checkins: Provides read access to the authorized user's check-ins or a friend's check-ins that the user can see.
Edit
My mistake, I missed seeing the publish_checkins permission in the list there...disregard.
Did you happen to try posting a checkin via the Graph API Explorer tool? Did it work?
