Budget Estimate API having content type application/xml is giving invalid response.

1. Send Budget soap request with content-type as "Application/xml"

<?xml version="1.0" encoding="utf-8"?>
<externalCampaignListWrapper xmlns="http://www.admaxlocal.com/external-api/budget">
<campaignList>
<externalCampaign>
<baId>150390</baId>
<distribution>YAHOO_JAPAN</distribution>
<locationId>400001</locationId>
</externalCampaign>
</campaignList>
</externalCampaignListWrapper>

2. Observe the response:

Actual result:

It shows the response UNSELLABLE_BUSINESS_ACTIVITY

{
"id": "bd13eaa0-5e8f-47fd-88d2-58ff8e2c97c6",
"estimates": [ {
"distribution": "YAHOO_JAPAN",
"status": "UNSELLABLE_BUSINESS_ACTIVITY",
"externalCampaign":

{ "baId": 0, "locationId": 0 }

}]
}

Note: Budget estimates with Conet-type application/json works fine.
