Can anybody explain me what is the use of access token once the user gets logged in using rest. I am trying to execute these webservices using rest client. I recieved the access token using this url http://localhost:firstname.lastname@example.org&password=123456, but dont know what to do next with this access token. Also in headers , I am not getting any jsessionid, due to which I am not able to add anything to cart. Please provide a detail step by step explanation on this.
