  • Patent number: 11823145
    Abstract: Methods and systems are presented for providing a framework to securely integrate third-party logic into electronic transaction processing workflow. Third-party programming code that implements different third-party logic may be obtained and stored in a repository. A transaction processing request is received from a third-party server, and an instance of a transaction processing module is instantiated within an operating runtime environment to process a transaction according to a workflow. When the instance of the transaction processing module has reached an interruption point, the instance of the transaction processing module is suspended, and a third-party programming code is executed within an isolated runtime environment. The third-party programming code is configured to provide an output value based on attributes of the transaction. The instance of the transaction processing module then determines whether to authorize or deny the transaction based in part on the output value.
