VB supports the batch request API which can be used to perform multiple operations(get, create, update, delete) in a single call.

The data is committed at the end of the requests, and if any one of the operations gets fails then the complete batch is rolled back.

The benefit of making batch requests is to increase the performance of the application as you can call multiple operations in a single call.

Below are the details of the batch requests REST APIs:

Sample Request

URL: <VB_BASE_URL>

HTTP Method: POST

Content Type: application/vnd.oracle.adf.batch+json

Sample Request:

{
   "parts":[
      {
         "id":"part1",
         "path":"/Employee",
         "operation":"create",
         "payload":{
            "firstName":”neeraj",
            "lastName":”kumar",
            "emailAddress":”nerraj.jain@gmail.com"
         }
      },
      {
         "id":"part2",
         "path":"/Employee/21",
         "operation":"update",
         "payload":{
            "emailAddress":"ankur.jain@gmail.com"
         }
      },
      {
         "id":"part3",
         "path":"/Employee/27",
         "operation":"delete"
      },
      {
         "id":"part4",
         "path":"/Employee/1",
         "operation":"get"
      }
   ]
}

Sample Response:
