Systems and methods are disclosed for cross-platform token exchange. One method comprises receiving a primary token exchange request from an upstream entity, generating an ancillary detokenization request based on the primary token exchange request, and transmitting the ancillary detokenization request to an input token vault. An ancillary detokenization response comprising sensitive data may then be received from the input token vault, and one or more ancillary tokenization requests may be generated based on the ancillary detokenization response and the primary token exchange request. The one or more ancillary tokenization requests may be transmitted to one or more output token vaults. Subsequently, one or more ancillary tokenization responses may be received from the one or more output token vaults, each ancillary tokenization response comprising an output token. A primary token exchange response may be generated based on the one or more ancillary tokenization responses and transmitted to the upstream entity.
