Redirect to the auth_url returned in the response and append the token value. Add an additional querystring parameter "r" with the URL you wish to direct the user to upon successful authentication. Based on the example response above, you would redirect the user to a URL that looks something like this: http://auth.integrify.com/auth/default.aspx?token=d995f821f18149779af827141576cf3b&r=http://back.to-my-app.com

Once the user authenticates, they will be redirected back to the URL specified in the "r" parameter (http://back.to-my-app.com.).

All REST Endpoints must be called with the application_key and token from the response above in the headers or in the querystring: ?key={application_key}&token={token}
