Question

I used the graph api in order to connect the user and publish an event on its wall.

But if I am connected as a page, I get this error message : “You need to be connected as a user and not as a page to run this app”

But I which I could publish my event on a fan page.

Here is my TOKEN_URL

How shoud I do to be able to publish on my fan page.
How can I enable that ?

Answer 1

To publish “on behalf” of a Page, you need to use a Page access token. To get a Page access token, first get an access token for a user with the manage_pages and publish_stream permissions:

https://graph.facebook.com/oauth/authorize?client_id=YOUR_APP_ID&
redirect_uri=YOUR_REDIRECT&scope=manage_pages,publish_stream&type=user_agent

Then, using the access token you get as a result, do a GET of:

https://graph.facebook.com/me/accounts?access_token=ACCESS_TOKEN_FROM_STEP_1

Here, you’ll find the list of the Pages the user is an admin of. Here you can grab the access token for one of these Pages. Now calls you make will be made on behalf of the Page. Now anything you try to post will be posted as the Page. If you are trying to create events, you may also need the create_event permission.

To see how this works, you can test this out using these URLs in your browser or in the Graph API Explorer.
