Calculating request signature

  • when the session_secret_key value is absent:
    • to call without session – session_secret_key = application_secret_key;
    • to call in session – session_secret_key = MD5(access_token + application_secret_key), convert the value to the lower case;
  • take session_key/access_token away from the list of parameters, if applicable;
  • parameters are sorted lexicographically by keys;
  • parameters are joined in the format key=value;
  • sig = MD5(parameters_value + session_secret_key);
  • the sig value is changed to the lower case.
