Tokens - Centrapay Docs

Tokens are Assets API which can only be spent in full.

Every Token is associated with a Collection, which defines the branding and general rules for the Tokens, such as active duration.

A Redemption Condition is created for each Merchant API that accepts Tokens from a Collection, and contains additional conditions specific to that Merchant, such as redeemable product identifiers.
