There are two ways you can do this.
1. All unrecognized transactions that we think belongs to a product will show up when you hit the “Needs Confirmation” tab on your Transactions screen.
We've tried our best to keep it as simple as possible for you to give this screen a quick eye-over, and either confirm or deny what product Siftery thinks an unrecognized transaction belongs to.
2. In cases where Siftery is unable to suggest a product for an unrecognized transaction, you can hit the ‘receipts’ icon on your right (this is the one that says ‘Unrecognized Transactions’ on hover). Once you find a transaction here that you think should belong to a product, hit ‘Map’ and the rest is easy as pie.
