This page is about the getInfo method for WebAPI Client authentication.

Validates the Authentication Token issued by clientLogin method and returns user's loginId, displayName and the authentication time stamp. This method also provides a way (see 'reqRights' argument below) for the client to obtain user's consent and manage it securely.

Initial Request

• URL
  • http(s)://api.screenname.nina.bz/auth/getInfo
• HTTP Method
  • GET or POST
• Arguments
  • devId (required)
    • your developer Id required to access NINA APIs
  • f (required)
    • the required format of the response (XML, JSON, or the query string)
  • language (optional)
    • the required language and locale of the error/status messages. This is always in "<lang>-<locale>" format. The lang is the 2 letter language code for I18N (default: en) and the locale is the 2 letter Locale code for I18N (default: us). If not passed in, the language will be extracted from HTTP header (Accept-Language) and if that is not available will default to "en-us". Check below for our current supported language list.
  • reqAuthFreshness (optional)
    • required Authentication freshness in secs ( time since the user was last authenticated). Default is 24 hrs (86400 secs)
  • c (optional)
    • the callback method to use when using jsonp convention (argument f = json)
  • r (optional)
    • an URL safe string to be used as requestId - when passed it is returned back in the response
  • a (required)
    • the Authentication token returned by login or getToken methods
  • ts (required)
    • current timestamp in seconds since epoch used to make sure the request cannot be replayed after a few mins
  • sig_sha256 (required)
    • Base64 encoded digital signature (HMAC-SHA256) of the request using the Session Key generated as below.
      • Session Key = base64_encode[HMAC-SHA256(key, data)] where key is the user's password and data is the session secret obtained from clientLogin response.
    • Please refer to Signing Requests for information about how to generate signature.
