Your Group ID only consist of numbers, for example:
115227675156013. If you do not know your groups' Facebook ID, we can find it for you through the Facebook ID helper-page.
To link directly to the your group's Wallflux Atom use the following URL:
?hl=fr_FRfor French to the URL.
A registered Wallflux Atom carries no demonstration notice, is not being cached for up to an hour and reports up to ten recent Wall-posts (instead of five items for unregistered feeds).
Depending on how you parse your Wallflux Atom, you are probably able to make the results look like your own site by applying CSS-styling. You can start by using an example CSS style sheet - or live fiddle with CSS below:
Don't hesitate to share your styled Wallflux Atom with @Wallflux!
Be aware that the images displayed in a Wallflux Atom are still served by Facebook's CDN. In principle, Facebook could use the retrieval of those images to track your RSS-reader or users of a website where a Wallflux is included. Due to technical limitations, it is not likely that Facebook retrieves your users' Facebook ID, making Wallflux Atom still less intrusive than Facebooks' own Social Plugins.
If you are looking for a text-only RSS feed for your Facebook groups or events, stripped from all content from FB's servers, try the regular Wallflux here.
Unregistered Wallfluxes are cached, so if you're not the first one making a language choice in a short time, it might be you served a localised, cached Wallflux Atom.
If you are being redirected to a plain-text Wallflux feed, without images, chances are that you are not using the ID of a Facebook group but for example of a FB page or a FB user.
