API for interaction between Annex and FB, similar to VC



  • In order to avoid authorizing the user on its server, it may be possible to verify that auth_key is correct in the interaction of its application and BC:

    auth_key = md5(api_id + '_' + viewer_id + '_' + api_secret)

    where auth_key is the key to authorizing the user on the outside server.

    api_id is the id of the initial application.

    viewer_id is the id of the user who sees the annex. api_secret - protected secret key.

    Question... Is there a similar formula for FB? And if so, can you describe it (and where it comes from) or make a specific reference to it (formula) and a description?



  • There is a similar formula for FB. It's a little more complicated, but in general, the same approach. It probably doesn't make sense. Can be consulted https://developers.facebook.com/docs/games/gamesonfacebook/login Section "Подписанный запрос"
