Example Request

This example updates the traffic limiting rules for tasks in the task group with ID xxxxxxxx by setting start to 00:01, end to 23:59, and max_bandwidth to 50000000.

/v2/{project_id}/tasks/batch-update

{
  "group_id" : "xxxxxxxx",
  "bandwidth_policy" : [ {
    "start" : "00:01",
    "end" : "23:59",
    "max_bandwidth" : 50000000
  } ]

This example updates the traffic limiting rules for tasks with IDs 111 and 222 by setting start to 00:01, end to 23:59, and max_bandwidth to 50000000.

/v2/{project_id}/tasks/batch-update

{
  "ids" : [ 111, 222 ],
  "bandwidth_policy" : [ {
    "start" : "00:01",
    "end" : "23:59",
    "max_bandwidth" : 50000000
  } ]
