Verifying the operational status of a Facebook Open Graph Entity

Question

Verifying the operational status of a Facebook Open Graph Entity

When making a call to post an action on an object, how can you determine if a user has already taken that action on the object? If the call is switched to "get" instead of "post", it will retrieve all the user's actions, not just the current object's. Also, replacing the first argument with the object's URL will result in an error.

It is important to clarify that I am interested in knowing whether the user took the action in the past, like yesterday, or at some previous time, and not just checking the success of the current call.

        FB.api('/me/namespace:action', 'post', likeOpts, 
        function(response) {
            if (!response || response.error) {
                console.log(response.error);
            } else {
                // success
            }
        });

To ensure that the post appears in their feed, you must verify the user's access token for the application. I recently conducted a trial with open graph to verify this process by examining my own feed. However, when dealing with another user, it is important to capture and populate the access token before it expires using the FB graph explorer tool.

There is no direct method to achieve this task.

To address this issue, it is recommended to store previous user actions in your database or mark them as completed using a boolean variable. Alternatively, you can retrieve the last action performed by the user by checking the response of /me/namespace:action request. Look for the current object URL within this response.

If the user attempts to perform the same action twice, an error will be thrown during a read action.

If the action results in an action instance ID being returned, it indicates a successful call and should be saved for future reference.

FB.api(
'/me/namespace:action',
'post',
{ OBJECT_TYPE: 'OBJECT_URL' },
function(response) {
   if (!response || response.error) {
      alert('An error occurred');
      console.log(response.error);
   } else {
      alert('Task completed successfully! Action ID: ' + response.id);
   }
});

Although my initial question has evolved, this answer may not be a perfect fit. However, it's what I ultimately used and I believe it could be helpful for future viewers.

To determine if a specific user has liked a particular object, I utilize the following FQL query through the js sdk. If the user has liked the object, it will return an array with their id. If not, it will return an empty array:

        FB.api({
            method: 'fql.query',
            query: 'select user_id from like where user_id=' + UserIDVar + ' and object_id=' + ActionIDVar,
            return_ssl_resources: 1
        }, function(response){
            console.log(response);
        });

You can adjust the FQL query to fit your requirements, and reference the documentation here: https://developers.facebook.com/docs/reference/fql/like/
