SiteData.asmx does not return any resources on SharePoint Online

Question

We're using SOAP API to get SharePoint Online data. I know SOAP API is deprecated but it works for a long time as same as SharePoint (On-Prem) servers.

From this weekend, SiteData.asmx does not return any resources. Was there any update about this SOAP API? We didn't change any configurations from last week.
I can call other API as expected, such as Lists.asmx. Also I confirmed the entire flow by testing my SharePoint (On-Prem) server.

We call SiteData.asmx API as follows.

Request:

• POST https://<tenant>.sharepoint.com/_vti_bin/SiteData.asmx
• Header: "Content-Type: text/xml"
• Body:
  <?xml version="1.0" encoding="utf-8"?>
  <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
  <GetContent xmlns="http://schemas.microsoft.com/sharepoint/soap/">
  <objectType>List</objectType>
  <objectId><List UUID></objectId>
  <folderUrl/>
  <itemId>-1</itemId>
  <retrieveChildItems>true</retrieveChildItems>
  <securityOnly>false</securityOnly>
  </GetContent>
  </soap:Body>
  </soap:Envelope>

Response:

• Body:
  <GetContentResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <GetContentResult />
  </GetContentResponse>

If someone can provide any response for this matter promptly, it would be appreciated. Thanks in advance.

@Frederic LARDE

Thanks to our customers, they escalated to Microsoft and the API change seems to be reverted. I verified our product is working fine now.

Thanks for your comment to sort out the situation!

Answer 2

I have the same issue and I didn't find any changelog/release note talking about this new behavior.

Hi @Sayaka Kuroki ,
Per my test ,We can use the following sample to get content
POST /_vti_bin/SiteData.asmx HTTP/1.1
Host: xxx.sharepoint.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://schemas.microsoft.com/sharepoint/soap/GetContent"

<?xml version="1.0" encoding="utf-8"?>  
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">  
  <soap:Body>  
    <GetContent xmlns="http://schemas.microsoft.com/sharepoint/soap/">  
      <objectType>VirtualServer or ContentDatabase or SiteCollection or Site or List or Folder or ListItem or ListItemAttachments</objectType>  
      <objectId>string</objectId>  
      <folderUrl>string</folderUrl>  
      <itemId>string</itemId>  
      <retrieveChildItems>boolean</retrieveChildItems>  
      <securityOnly>boolean</securityOnly>  
      <lastItemIdOnPage>string</lastItemIdOnPage>  
    </GetContent>  
  </soap:Body>  
</soap:Envelope>  

And it will return like following
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>  
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">  
  <soap:Body>  
    <GetContentResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/">  
      <GetContentResult>string</GetContentResult>  
      <lastItemIdOnPage>string</lastItemIdOnPage>  
    </GetContentResponse>  
  </soap:Body>  
</soap:Envelope>
