Hi Matt,
In order to have a better resolution to your problem, can you give me an example of a query you would do with a MethodAPIUpdateV2?
With a change of code if there is a duplicate name, but you are not editing the name field itself, then you should not be getting any error messages and the record will be updated with data you had passed in.
So for example if we have two customers with name "Mike":
Scenario 1 (This will FAIL and will not update the values): MethodAPIUpdateV2(strCompanyAccount, strLogin, strPassword, strSessionID, "Customer", "Name", "Mike", 12)
Scenario 2 (This will PASS and update the values): MethodAPIUpdateV2(strCompanyAccount, strLogin, strPassword, strSessionID, "Customer", "AccountNumber", "777", 12)
