Computerized aggregation and transaction processing architecture for digital health infrastructure

A digital health solution system, comprising:

• a virtual pharmacy comprising one or more processors configured to operate a web portal for user devices via a network, the web portal serving as a marketplace for products and services available from vendors for consumption by users;
• a transaction processing module configured to:
• receive, via a network and a first application programming interface (API), a batch of transactions from a first vendor regarding one or more of the products and services consumed by users via the virtual pharmacy for payment to the first vendor, each of the transactions of the batch of transactions having a first data structure;
• receive, via a network and a second API, a single transaction from a second vendor regarding one of the products and services consumed by a single user via the virtual pharmacy for payment to the second vendor, the single transaction having a second data structure that is different than the first data structure;
• adjudicate the batch of transactions and the single transaction using adjudication rules stored in memory;
• bill a first entity for the use of the one or more of the products and services associated with the one or more users when the adjudication of transactions of the batch of transactions passes;
• deny one of the transactions of the batch of transactions when the one of the transactions of the batch of transactions does not satisfy one or more of the adjudication rules;
• bill a second entity for the use of the one or more of the products and services associated with the single user when the adjudication of the single transaction passes;
• deny the single transaction when the single transaction does not satisfy one or more of the adjudication rules;
• transmit a first response regarding the adjudication of the batch of transactions to the first vendor;
• and
• transmit a second response regarding the adjudication of the single transaction to the second vendor.
