How can i consume a signed xml?


How can i consume a webservice that use a signed xml?, how can i pass the signature ?

I am new to ionic and following cconraets ionic tutorial and the sessions example using a factory

.factory(‘Session’, function ($resource) {
return $resource(‘http://localhost:5000/sessions/:sessionId’);

And andrew macgivery posts about soarp webservices

Thank´s in advance

The xml have this pattern : where i must pass a key to have access to the webservice
