How to post to my own page using the Facebook API

Question

I would like to post updates to a Facebook Page I own, using the API.

I followed the instructions in this answer to obtain:

1. a short-lived access token for my user, making sure to grant permissions for publish_stream and manage_pages
2. a long-lived access token, which the token debugger actually shows as never expiring
3. a Permanent Page Access Token specific for my page, which again is shown as never expiring

I can use the long-lived access token to post to my wall, but neither that nor the specific page access token allow me to post to my page.

If I try to use the personal long-lived access token to post to my Page ID, it returns OK and an actual post ID, but the post never appears on the page.

If I try to use the page access token to post either to /me/feed (which should be the page) or to the page ID, I get #200 The user hasn't authorized the application to perform this action which I clearly did.

What am I doing wrong?

Do I need to submit my app for review? How can I do so, when I don't even have an "app"? It has no public facing website, nothing, because it's only a single script for my own personal use, which I'd like to use to update my page.

Answer 1

according to the docs you will need publish_pages permission to post as page from api v2.3 . Prior, it needed permission publish_actions in addition to manage_pages. Now they have introduced publish_pages specifically for that purpose. .

A page access token with publish_pages permission can be used to publish new posts on behalf of that page. Posts will appear in the voice of the page.
