Operations And Examples

The Tasks endpoint is a part of the Create-Read-Update-Delete (CRUD) web resources present in midPoint. This is apparent in the operations which are available for this type of object.

In our examples we are authenticating with the credentials, name "administrator" and password "y0uR_P455woR*d" on a localhost instance running on port 8080.

How to use MidPoint REST examples

Create Task Objects

Create a new Task object in MidPoint with file data source
curl --user administrator:y0uR_P455woR*d \
-H "Content-Type: application/json" \
-X POST http://localhost:8080/midpoint/ws/rest/tasks \
-v \
--data-binary @./samples/rest/task-recompute-members-employee.json
Show data source example for "Create a new Task object in MidPoint" | GitHub 
{
  "task" : {
    "name" : "Recompute all direct members of Role Basic Employee",
    "schedulingState" : "ready",
    "binding" : "loose",
    "activity" : {
      "work" : {
        "recomputation" : {
          "objects" : {
            "type" : "UserType",
            "query" : {
              "filter" : {
                "text" : "assignment matches (targetRef matches (oid = '96262f4f-053a-4b0b-8901-b3ec01e3509c'))"
              }
            }
          }
        }
      }
    }
  }
}

The response is an HTTP 202 code in case of success without a response body. Also, the response contains a Location Header pointing to the location of the created user.

Example location header
Location: http://localhost:8080/midpoint/ws/rest/tasks/6d13632c-6b75-4a33-9744-ec9523375f6b
