So what I want to do is put a hashtag or something in each on my Tiny Sketchbook posts on Facebook, and then gather them all up on a page here on my WordPress blog. However, using the WordPress embed for Facebook to access the first of my Facebook drawing posts… did not work.

Looking at the WordPress embeds documentation…

…tells me that Facebook has decided to ‘close the oEmbed end point for embedding Facebook links’.

Well, it turns out that you now need to provide a FaceBook Application ID and an authentication token to use the Facebook API to display posts in other locations. I think. Facebook does provide ways to embed posts:

Fortunately (?) I have a Facebook developer account, from when I was taking web development at Durham. I went back in and discovered all the FaceBook apps I had written as assignments, forgotten, but still there after all this time. I archived them, and am now trying to refamiliarize myself with the whole thing.
