In some cases, you may desire to set up a QBP survey as per UI.

This can be accomplished using the QBP API.

The QBP feature must be enabled from an operator to use this API

Request

POST $apihost/$basepath/buyers/v2/surveys

($apihost is the environment against which you are testing, and $basepath is the base path with the api version. All Buy API calls will require access-token parameter in the header) 

Request Payload when QBP is Enable:

{
  "qbp" : {
    "enable": true,
    "quota_ids": [
      "abc", // buyer_quota_id
      "xyz"
    ]
    "category": "Age" // optional in case of UI.
  }
}

Request Payload when QBP is Disable:

{
  "qbp" : {
    "enable": false
  }
}
