What is a retrieval request?

A retrieval request or, so called pre-chargeback, is a notification sent by the acquiring bank to a merchant with the request to present an invoice or relevant documentation about a particular transaction. If the documentation submitted by the merchant satisfies the requirements of the bank, the retrieval will not reach the chargeback, but if the response is not satisfactory, the retrieval will become a formal chargeback.

The difference between retrieval and chargeback is that the retrieval is a warning without economic consequences and the chargeback is an economic claim to trade.
