Is Facebook's token_for_business unique for a user?

Question

Here's a good guide on how to use Facebook's Business Mapping API:

https://developers.facebook.com/docs/apps/for-business

It's however unclear if a user's token_for_business is unique for that particular user. It's also unclear if the token will expire at any time.

The name itself, "token", hints that it is a value that will expire.

Insights on this would be appreciated. Thanks!

Answer 1

Yes, it is unique for one particular user. It should not expire, especially not if the user stay authorized in the Apps.

...a string which is the same for this person across all the apps managed by the same Business Manager

Important:

If the owning business changes, the value of token_for_business will also change
