Constructor Details

#initialize(params_sent, api_username = nil) ⇒ OAuth2

Returns a new instance of OAuth2.

Parameters:

  • params_sent (Hash) —

    Parameters to make OAuth request

  • api_username (String) (defaults to: nil) —

    Username to use which can be set by Soaspec::ExchangeHandler

Options Hash (params_sent):

  • URL (token_url) —

    to retrieve OAuth token from. @Note this can be set globally instead of here

  • Client (client_id) —

    ID

  • Client (client_secret) —

    Secret

  • Username (username) —

    used in password grant

  • Password (password) —

    used in password grant

  • Security (security_token) —

    Token used in password grant
