SOAP API request returns 405

Question

I want to get SubscriberStatusEvent using:

https://developer.salesforce.com/docs/marketing/marketing-cloud/guide/retrieving_the_subscriberstatusevent.html

the following code returns OK but there is no data. What might be the problem?

    <?xml version="1.0" encoding="UTF-8"?>
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">

POSTMAN Python code:

import http.client

conn = http.client.HTTPSConnection("DOMAIN.soap.marketingcloudapis.com")

I'd definitely recommend testing any SFMC API call in Postman first. The SFMC Collection is more recent (and relevant) than the SDKs.

You're missing part of the endpoint URL. Here's a Python export from Postman for my test call:

import http.client

conn = http.client.HTTPSConnection("YOURTENANT.soap.marketingcloudapis.com")
payload = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<s:Envelope xmlns:s=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:a=\"http://schemas.xmlsoap.org/ws/2004/08/addressing\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">\n <s:Header>\n <a:Action s:mustUnderstand=\"1\">Retrieve</a:Action>\n <a:To s:mustUnderstand=\"1\">https://YOURTENANT.soap.marketingcloudapis.com/Service.asmx</a:To>\n <fueloauth xmlns=\"http://exacttarget.com\">YOURAUTHTOKEN</fueloauth>\n </s:Header>\n <s:Body xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">\n <RetrieveRequestMsg xmlns=\"http://exacttarget.com/wsdl/partnerAPI\">\n <RetrieveRequest>\n <ObjectType>SubscriberStatusEvent</ObjectType>\n <QueryAllAccounts>true</QueryAllAccounts>\n<Properties>Client.ID</Properties>\n<Properties>CreatedDate</Properties>\n<Properties>CurrentStatus</Properties>\n<Properties>ObjectID</Properties>\n<Properties>PreviousStatus</Properties>\n<Properties>ReasonUnsub</Properties>\n<Properties>SubscriberID</Properties>\n<Properties>SubscriberKey</Properties>\n </RetrieveRequest>\n </RetrieveRequestMsg>\n </s:Body>\n</s:Envelope>"
headers = {
  'Content-Type': 'text/plain'
}
conn.request("POST", "/Service.asmx", payload, headers)
res = conn.getresponse()
data = res.read()
print(data.decode("utf-8"))

Please check your BU unsubscribe settings within Setup. My understanding is that the SubscriberStatusEvent will only populate if you have configured the BU's Unsubscribe Settings as: Subscribers will be unsubscribed from all business units in the Enterprise.

Furthermore, you MUST ensure that you create and license your installed package in the TOP LEVEL parent account.

If anyone is attempting to retrieve via WS Proxy, then you need to execute the code in the PARENT Business Unit since impersonation does not work bottom-up.

The key clue is in the documentation:

This call only logs events at the All Subscriber list level.

Since the All Subscribers list exists at the enterprise level, then this particular API call needs to be made at the enterprise level as well.
