I am using the .NET SDK to make a call to GetSessionID and I get the following error:

<FaultDetail>
<ErrorCode>35</ErrorCode>
<Severity>Error</Severity>
<DetailedMessage>Invalid user name or password. The username/password pair specified for the user is not valid. You may not use an email address as a username if the member has a User ID.</DetailedMessage>
</FaultDetail>

Why am I getting this error?


Detailed Description

This issue happens only in SDK versions earlier than 595. 

For most of the calls a user token is expected.  However, in the case of GetSessionID, you do not send any user token, since the call itself is used to help get a token.  Since there no token, it sends in an empty UserID and Password field, which causes the error.

If you look at the log file, this is what it sends:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Header>
  <RequesterCredentials xmlns="urn:ebay:apis:eBLBaseComponents">
    <Credentials>
      <AppId>appid</AppId>
      <DevId>devid</DevId>
      <AuthCert>******</AuthCert>
      <eBayAuthToken>XXXXXXXX</eBayAuthToken>
     </Credentials>
  </RequesterCredentials>
  </soap:Header>
  <soap:Body>
  <GetSessionIDRequest xmlns="urn:ebay:apis:eBLBaseComponents">
    <MessageID>f61d5418-150e-4cc5-8dbe-ea30db6a86eb</MessageID>
    <Version>561</Version>
    <RuName>your_runame</RuName>
  </GetSessionIDRequest>
  </soap:Body>
</soap:Envelope>

To resolve this issue, you need to explicitly set the eBayAccount property to null as below:

C#
context.ApiCredential.eBayAccount = null; 

VB.NET
context.ApiCredential.eBayAccount = Nothing
