In order to earn cash back on all of your favourite brands, Ampli needs to be able to see that you have completed a transaction associated with an active Ampli offer. We use third-party account aggregation technology to match active Ampli offers with the purchases you make with the debit and/or credit card(s) you link to your Ampli account. Our service provider uses your hashed login credentials to provide us with transaction information from your linked accounts.
