to confirm
'bestätigen' and 'zertifizieren' both have to do with an official statement that something is correct or meets certain conditions. 'bestätigen' is more general: you can confirm an appointment, receipt of a message, or a piece of information. 'zertifizieren' is more specific and more formal. It means that a recognized body checks and certifies that a person, product, or process meets certain standards. The words can be confused because both sound official.
