What do the Token Manager values: 'Persistent' and 'Volatile' mean

The Token Manager value controls how tokens are persisted.

With the default, Persistent mode tokens will be stored on the database infinitely just as you may expect.

With Volatile mode tokens will be stored only for 30 minutes - that is the default value and can be configured. It is useful when you cannot keep some information in your system due to compliance but still need to use it for a series of requests. One example would be getting a PIN from a client and using it for a request to third-party service.

One important note is that you can reveal tokens only with rules of the same persistent mode they were created with. E.g. if you have the rule to redact PIN value with Volatile storage, a revealing rule with Volatile storage will work for that token but Persistent won't and vice versa.
