# BankConnect: Fraud
There are some frauds which are detected at the first step when the statement file is successfully uploaded, these are called Metadata frauds and are returned as a response to upload API.
Examples of a metadata
author_fraud, which indicates that author of the document is not a trusted source for this bank statement.
Other fraud checks require analysis over the extracted transactions and are hence available (along with the Metadata frauds) in the
fraud_type array in
fraud field in all transaction APIs.
There is usually a field
fraud_type that indicates the fraud type. The list of possible
fraud_type values can be acquired on request from the FinBox team.
A general rule of thumb would be that the fraud_type is usually in a string format with all lower case and words separated by an underscore (_). So a fraud type term can be formed by simple string manipulation of replacing underscore with spaces and making the first character capital in each word then. Example:
some_fraud_type can become
Some Fraud Type.
fraud_category indicates the category of fraud.
metadata is the category for Metadata frauds. Other fraud categories can be acquired on request from the FinBox team.
