• The REST Web Service API is called by using an HTTP client that sends JSON based requests and that receives JSON based responses.
• The following REST Web Service API requests are supportedavailable:
  • URL joc/api/authentication/login
    • The first operation of a client should be is call to this URL in order to authenticate and to retrieve an access token.
    • A valid account and password have to be provided by the client for HTTP authentication.  The account and permissions for the command(s) to be executed are configured with the shiro.ini configuration file. See the Authentication and Authorization - Configuration article and the example api_user configuration for further information.Use the joc/api/authentication/joc_cockpit_permissions URL to retrieve the permissions for the current userFor HTTPS connections in addition or alternatively JS7 - Certificate based Authentication can apply, for details see JS7 - Identity and Access Management.
    • Permissions apply as explained by JS7 - Management of User Accounts, Roles and Permissions.
  • URL  joc/api/* 
    
    • Subsequent calls to URLs can e.g. for example retrieve the inventory and current information about workflows and ordersof workflow.
    • Find the respective URLs from the Technical Documentation of the REST Web Service API
    • The JS7 REST Web Service API will return returns the respective JSON response indicated with the docs.
  • URL joc/api/authentication/logout
    • The last operation of a client should be is a call to this URL in order to logout from the REST Web Service API.
• Requirements
  • REST Web Service API requests should use HTTP POST or GET operations as indicated.
  • Should an the idle timeout of 15 minutes between two web service requests be exceeded then the current session is invalidated and exceed the JOC Cockpit session timeout then a login has to be performed. The timeout value can be adjusted with shiro.ini.

Examples

• Example: Get the list of orders scheduled until a given date
  • Find attached example order_list_sample.sh for use with curl. We do not consider curl to be perfectly prepared to handle web service requests, however, it shows the building blocks:

    • Explanations

      • Line 4: Depending on your JOC Cockpit installation the protocol will be http or https. The default port is 4446 but might have been modified during setup.
      • Line 7: The Controller ID is specified during installation of the Controller and identifies a Controller standalone instance or a Controller cluster.
      • Line 10: Specify the relative date up to that you want the list of scheduled orders to be returned.
      • Line 13, 14: Default credentials after installation include the account "root" and password "root". The credentials might have been changed after setup of JOC Cockpit.
      • Line 22: Consider to use Basic HTTP authentication
      • Line 23: The request to the /authentication/login web service returns an access token that is used with further requests.
      • Line 32, 33: Consider the JSON body created for the request and the URL including the path /joc/api/orders used to return order information.
      • Line 42: Always perform a logout and consider the session idle timeout.
• Example: Suspend an order
  • Find attached example order_suspend_sample.sh for use with curl. We do not consider curl to be perfectly prepared to handle web service requests, however, it shows the building blocks:

  • Explanations
  • Line 31: Suspending an order includes to specify the Controller ID and an array of order IDs..
  • Line 38: The operation to suspend an order works asynchronously as the request is forwarded to the Controller and from the Controller to the Agent that holds the order. More elaborate solutions to wait for completion of an suspend operation than just to wait a few seconds include to repeatedly check the order state.
  • Line 47: The request to retrieve the order state information is sent to the /joc/api/orders URL.
  • Line 58: Always perform a logout and consider the session idle timeout.
