To use API calls , first you will need to authenticate with a valid username and password.
To use the login API find the instructions below :
url : http(s)://yourserverIP_or_DomainName/api/auth/login
Method : Post
In case of a success login , the API will return a JW token which is valid to use for 4 hours. After this period you need to generate a new JW Token to use.
This token is used in every API call for the management system , as authorization.
