One method comprises receiving, by a token exchange service system, a primary tokenization request from an upstream entity, generating, by the token exchange service system, one or more ancillary tokenization requests based on the primary tokenization request, and transmitting, by the token exchange service system, the one or more ancillary tokenization requests to respective one or more output token vaults. One or more ancillary tokenization responses may then be received from the one or more output token vaults, and a primary tokenization response may be generated based on the one or more ancillary tokenization responses. The primary tokenization response may be transmitted to the upstream entity. ## Claims ### Claim 1 A computer-implemented method for cross-platform token compatibility, comprising: providing, by a token exchange service system, a portal to a merchant system through which the merchant system provides output token service provider configuration identifiers and activates token service providers corresponding to the output token service provider configuration identifiers;

and at least one data storage comprising instructions which, when executed by the one or more processors, cause the one or more processors to perform a method comprising: providing, by the token exchange service system, a portal to a merchant system through which the merchant system provides output token service provider configuration identifiers and activates token service providers corresponding to the output token service provider configuration identifiers; receiving, by the token exchange service system, the output token service provider configuration identifiers and an activation of the token service providers corresponding to the output token service provider configuration identifiers from the merchant system via the portal; receiving, by the token exchange service system, a primary tokenization request including sensitive data of a user of the merchant system and the output token service provider configuration identifiers from an intermediary system that is provided between the merchant and the token exchange service system; generating, by the token exchange service system, a globally unique identifier (GUID) based on the received primary tokenization request, the GUID stored in a database of the token exchange system; determining, by the token exchange service system, a plurality of output token vaults that are associated with the plurality of token service providers communicating with the token exchange service system to which the sensitive data is to be routed for tokenization based on the output token service provider configuration identifiers included in the primary tokenization request and based on the activation of the token service providers corresponding to the output token service provider configuration identifiers received from the merchant system via the portal; generating, by the token exchange service system, ancillary tokenization requests based on determining the plurality of output token vaults to which the sensitive data is to be routed for tokenization;
