System and Method for Integrating External Services into Process Workflow Environments

Abstract:

A system and method are provided for integrating external services into process workflow environments. The method can include subscribing to one or more topics in an external domain coupled to at least one external microservice to be notified of incoming messages, the topics in the external domain being mapped to topics in an internal domain coupled to a message broker for routing messages within the internal domain. The method can also include subscribing to the one or more topics in the internal domain to be notified of outgoing messages to the at least one external microservice and detecting an incoming message published to a first topic by a first external microservice. The method can also include sending the incoming message to the first topic of the internal domain, detecting an outgoing message from the first topic or a second topic of the internal domain, and publishing the outgoing message to the first external microservice or another external microservice via a corresponding topic in the external domain.
