Apache Synapse HTTPS Listener
Port 8243 is primarily used as the default HTTPS listener endpoint for Apache Synapse and WSO2 API Manager. It facilitates secure, encrypted communication over SSL/TLS for API management, mediation, and integration tasks. This port allows clients to securely connect for API publishing, invocation, and governance operations..
Apache Synapse, often deployed as part of the WSO2 API Manager platform, uses port 8243 as a default TCP/UDP endpoint secured via HTTPS. Serving as the front door to API services, this port manages all incoming encrypted traffic for API requests, management, and mediation activities. Since it supports SSL/TLS protocols, data confidentiality and integrity between clients and the API gateway are ensured.
This listener endpoint enables key functionalities like API routing, request/response transformation, logging, throttling, and mediation while maintaining secure connections. When integrated with an identity server, authentication and authorization mechanisms are enforced over HTTPS through port 8243. The multi-protocol capability (TCP and UDP) enhances the flexibility of communication in hybrid environments.
Administrators typically bind this port to services responsible for mediating, managing, and exposing APIs to both internal and external consumers. Given its encryption support, sensitive configuration data, token management, and API traffic can traverse the network with reduced risk of interception or leakage, making it integral to secure API operations.
