Trying to authenticate to a Salesforce community org (External Identity License) from an external application using OpenID / OAuth 2.0. Can the OAuth flow accept a language parameter in the header or url and render a translated screen? How? I can't find anything in the documentation.
I believe I could do something custom if I roll my own OAuth endpoint and drop a language cookie from a passed parameter but looking for an OOB solution for standard oAuth? Anybody have any experience or can help?
What I could find by googling was 1) Twitter uses lang=de_DE 2) Facebook uses locale=es_ES 3) No mention of lang or locale in http://tools.ietf.org/html/rfc6749 4) OpenID Connect has ui_locales http://openid.net/specs/openid-connect-standard-1_0-21.html 5) I can't find anything on Salesforce's documentation about oAuth and lang support
If it's not supported what is the standard?
