To save links to del.icio.us we need to make an HTTP GET request to the following URL:
https://api.del.icio.us/v1/posts/add
The minimum parameters required are the URL of the link to be added, and a description. For example:
https://api.del.icio.us/v1/posts/add?url=http://skimstone.x-port.net&description=The+skimstone+site.Other parameters can be added, and they include more detailed notes about the link, a space-separated list of tags, a timestamp, a flag to indicate whether to replace any pre-existing information (if there is any) and a flag to indicate whether to keep the link private.
Details of other commands that can be used with posts are at http://del.icio.us/help/api/posts.
