HL7 Integration Using Mule Healthcare Toolkit- Part 1

The Mule Healthcare Toolkit is a collection of features that facilitates integration with healthcare systems by providing the tools needed to easily create, read, and transform HL7 messages within Mule. Health Level Seven International is a standards development organization that defines a set of standards for the transport and communication of healthcare information. The version of the MuleSoft HL7 connector is different from the HL7 version numbering. The HL7 connector only supports HL7 software versions v2.1, v2.2, v2.3.1, v2.3, v2.4, v2.5, v2.5.1, v2.6, 2.7, 2.7.1, 2.8, and 2.8.1. HL7 software version 3.0 is not supported.

The Mule Healthcare toolkit allows you to send and receive HL7 messages over MLLP and other transport protocols and corresponding connectors supported by Mule, such as HTTP. Minimal Lower Layer Protocol (MLLP) uses the HL7 MLLP connector.
