Developed SOAP headers support in the BoxSoapClient for the ortus-boxlang/BoxLang repository, focusing on enhancing interoperability with SOAP-based web services. The work involved implementing the injection of custom SOAP headers into the SOAP envelope, allowing for more flexible and enterprise-ready API integrations. Using Java and leveraging unit testing, the developer ensured robust header handling by expanding test coverage and validating header behavior. The feature-focused delivery did not include major bug fixes but prioritized reliability and CI readiness. This contribution improved the ability of BoxLang to interact with external SOAP services, supporting more complex integration scenarios for enterprise applications.
