How to use for IndieAuth
It has been proposed that WAM could be used for Client Information Discovery in IndieAuth. There are some simple steps to be able to do this.


 * When checking for a, check for   (More information on obtaining a WAM url can be found here).
 * If  is not found, fallback to mf2 parsing or other fallback
 * If  is found, create the manifestUrl by grabbing the   attribute from the element. If there is no http prefix, add the client_id to the beginning of the   string.
 * Make a GET request to the manifest url and parse the response as JSON.
 * the  attribute becomes the app name
 * one of the items in the  array can become the app logo. Note, there can be different icons of different sizes. You'll want to grab the appropriate one based on its size.
 * The icons array contain objects that are src (the image url), sizes (a string about the size of the image at that url) and type (mime type).

Eddie Hinkle
added WAM parsing support into abode's Authorization endpoint on Aug 21, 2018, the code is open source and can be found here.

WordPress
added basic WAM parsing support into the Wordpress_IndieAuth_Plugin on August 23, 2018.

The plugin searches for a manifest and uses the icon and name data from there. If not, it looks for an 'icon' link, then 'apple-touch-icon', etc. It does not currently look by size and picks the first one. For name, it falls back onto application-name as noted by the manifest specification, if not it will look for an og:title, then a title tag.
