In addition to tagging, the linkedId lets you connect an identification event with a custom identifier that is indexed by Fingerprint Pro. This lets you filter visit history when querying the server API. Unlike tags, the linkedId is a string. Objects or non-string values are not supported.
The server API returns identification events up to 30 days in the past. For information critical to your business, we recommend storing copies of this data on your own servers. Enterprise plans include unlimited server-side storage of identification events.

Do not expose the server API key in production. You can make requests from the server side using our official Node.js wrapper. If you need to access the server API in production, it is recommended you perform authorization via auth headers instead of using the api key inside the endpoint.
