I'm using Postman to test my API skills in Marketing Cloud. I created the following SOAP API to pull some details on a specific Send.
FYI, the endpoint is : https://YOUR_SUBDOMAIN.soap.marketingcloudapis.com/Service.asmx;
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Header>
<fueloauth>{{accessToken}}</fueloauth>
</Header>
<Body>
<RetrieveRequestMsg xmlns="http://exacttarget.com/wsdl/partnerAPI">
<RetrieveRequest>
<ObjectType>SendSummary</ObjectType>
<Properties>AccountEmail</Properties>
<Properties>AccountID</Properties>
<Properties>AccountName</Properties>
<Properties>Client</Properties>
<Properties>SendID</Properties>
<filter xsi:type="SimpleFilterPart">
<Property>ID</Property>
<SimpleOperator>equals</SimpleOperator>
<value>692734</value>
</filter>
</RetrieveRequest>
</RetrieveRequestMsg>
</Body>
</Envelope>
Can someone please tell me why the response is coming out :
WSE012: The input was not a valid SOAP message because the following information is missing: action.
