ILEusion API documentation

Starting the ILEusion Server

All APIs are enabled when the ILEusion server is started. You can start the server (or multiple servers) using the STRILESRV command after installation. The command also has optional parameters.

ADDLIBLE ILEASTIC
ADDLIBLE NOXDB
ADDLIBLE ILEUSION
STRILESRV

API authorisation

All APIs are run within the same job, but in seperate threads.

If LOGIN is enabled, when making a request to the ILEusion HTTP server you are required to pass the Authorization header with a Basic username and password (in base64). This does mean, that requests will run under the supplied user profile - it will use that users authorities, not the users that is running the ILEusion server. It is recommend that you call the ILEusion via an SSL enabled proxy to secure the username and password.

Authorization: Basic bXl1c2VycHJmOm15cGFzc3dvcmQ=

If LOGIN is disabled, then it will use the user profile that started the ILEusion job and no Authorization header is needed.

Calling ILEusion through Db2

You are also able to call ILEusion APIs through a Db2 stored procedure. For example, you can use a database library in your Node.js or PHP app and that would use the database to authenticate the user (and manage their authorities). Then you can use the database to call the ILEusion stored procedure to call any of the available APIs.

Not yet implemented. See relevant GitHub issue

API documentation

All APIs accept and respond with JSON. All APIs will return an object with success: false if it fails, along with message. Not all APIs return with success: true.

APIs available:

/transaction

/transaction allows ILEusion to process multiple transaction in one request. Meaning you could call a program, insert into a data queue and call a CL command in a single API call.

The body must be an array of objects, where the object is what matches the API you want to call (see the available API documentation) - but must also contain an action attribute which is the API it’s going to use.

Example input

[  
   {  
      "action": "/dq/send",
      "library": "BARRY",
      "object": "TESTDQ",
      "data": "This is my test!!"
   },
   {  
      "action":"/cl",
      "command": "addliliohls"
   }
]

Example response

[  
   {  
      "success": true
   },
   {  
      "success": false,
      "message": "Error during execution of command."
   }
]

/sql

/sql allows you to run select statements.

The request body has 1 required and 2 optional attributes:

Example input

{
  "query": "select * from product where MANUID = 'SAMSUNG'"
}

{
  "query": "select * from product where MANUID = '$manu'",
  "parameters": {
    "manu": "SAMSUNG"
  }
}

{
  "mode": 4,
  "query": "product",
  "parameters": {
    "manu": "SAMSUNG"
  },
  "where": "prodno = 120"
}

/call

/call allows you to call an ILE application or service program function. The result is an array of values which is the values passed by reference from the application. Currently only program calls are supported.

Request body

The request body has three main attributes:

Acceptable types: int, uns, float, char, bool, ind, packed, zoned, struct

Service program functions can be called, but you can only pass parameters in and out. The return value is not being handled yet (23). You can also only call each service program once per transaction (24).

Example request

Dcl-Pi FAK100;
  pText Char(20);
  pNum1 Int(10);
  pNum2 Int(10);
  pNum3 Int(10);
End-Pi;

{
	"object": "FAK100",
	"library": "BARRY",
	"args": 
 	[
		{
			"value": "Text here",
			"type": "char",
			"length": 20
		},
		{
			"value": 11,
			"type": "int",
			"length": 10
		},
		{
			"value": 10,
			"type": "int",
			"length": 10
		},
		{
			"value": 0,
			"type": "int",
			"length": 10
		}
	]
}

Example request (array)

Dcl-Pi FAK101;
  pText Char(20);
  pNums Int(10) Dim(3);
End-Pi;

{
	"object": "FAK101",
	"library": "BARRY",
	"args": 
  [
		{
			"value": "John",
			"type": "char",
			"length": 20
		},
		{
			"values": [
				3,
				666,
				5
			],
			"type": "int",
			"length": 10
		}
	]
}

Example request (struct)

Dcl-Ds DSTest Qualified Template;
  Name Char(20);
  Age  Int(3);
  Money Packed(11:2);
End-Ds;

Dcl-Pi DS1;
  pDS LikeDS(DSTest);
End-Pi;

{
        "library": "ILEUSION",
        "object": "DS1",
        "args": [
            {
                "type": "struct",
                "value": [
                    {
                        "type": "char",
                        "length": 20,
                        "value": "Hello"
                    },
                    {
                        "type": "int",
                        "length": 3,
                        "value": 11
                    },
                    {
                        "type": "packed",
                        "length": 11,
                        "precision": 2,
                        "value": 12.34
                    }
                ]
            }
        ]
}
