Systems and methods for use in facilitating network transactions

A system for processing transactions to payment accounts based on use of tokens in the transactions, the system comprising:

• a payment network coupled between an acquirer and an issuer and including at least one computing device, the at least one computing device including:
• a memory having a vault data structure including a mapping between tokens and primary account numbers (PANs) of multiple payment accounts;
• and
• at least one processor coupled to the memory;
• wherein the memory includes executable instructions, which when executed by the at least one processor cause the at least one processor to:
• 'receive a request to provision a token associated with a first one of the multiple payment accounts;
• generate an internal token in response to the request to provision the token;
• store a first map of the internal token to a first PAN in the mapping in the vault data structure, the first PAN specific to the first one of the multiple payment accounts;
• receive a bulk file from a token provider, the bulk file including multiple external tokens and multiple PANs, the multiple external tokens including an external token associated with a second one of the multiple payment accounts and the multiple PANs including a second PAN specific to the second one of the multiple payment accounts, wherein the multiple external tokens are generated by the token provider which is external to and separate from the payment network;
• in response to the bulk file, store a second map of the external token to the second PAN in the mapping in the vault data structure;
• intercept an authorization request message from the acquirer indicative of a transaction involving one of the multiple payment accounts;
• and
• when the authorization request message includes the external token:
• identify the second PAN associated with the external token based on the second map, from the mapping in the vault data structure;
• and
• provide at least one PAN-dependent service for the transaction based on the identified second PAN associated with the external token, whereby the at least one PAN-dependent service is available to the transaction based on inclusion of the external token in the vault data structure despite the external token being generated by the token provider.
