Response Breakdown

Below is some more information about the some of the elements of the response that require explanation:

DataSources = A collection showing every source of data that was used to formulate the result. Each source is represented by a MatchingSource element.

AllowMultipleRecordsAsSeparateDataSources= Indicates that two different record matches from the same data source may count as independent sources when formulating the 2 + 2 result. For example, two Insight results may count as two sources, rather than one, as they would do under normal service circumstances.

MatchingCriteria = Precisely what data has been matched by the data source. E.g. NameAndAddressAndDateOfBirth

NumberOfMatches = The number of matches found by this data source

Source = An integer representing the source of the data match. E.g. 2 = CCJ (County Court Judgement)

SourceIdSource Matched
1Electoral Roll
2County Court Judgements (CCJs)
4Credit Lenders (Insight)
6Mortality Data
7Credit Lenders(Call Credit)

InterpretResult = The overall verification result, based on what matches were found in the data source against the query data submitted. The possibilities are Pass, Fail or Refer

Message = Gives some more details / context on the verification result

TransactionResult = A diagnostic result showing whether or not any technical errors were experienced during the check. This should always be "Success" unless a technical error has occured, in which case the verification check will be aborted.

Example Response: The below example shows a case where we have found one NameAndAddress match on the Electoral roll and 3 NameAndAddressAndDateOfBirth matches on CreditLendersB. This has resulted in a Pass.
