Anypoint Connector for HTTP (HTTP Connector) enables you to declare HTTP servers that listen to
requests and trigger flows, as well as HTTP clients that can communicate with any HTTP service.

Guide: [HTTP Connector User Guide](https://docs.mulesoft.com/http-connector/latest/)

## 1.12.0

**August 4, 2026**

### What’s New

**May 14, 2026**

### Fixed Issues

<table><colgroup><col> <col></colgroup><thead><tr><th>Issue Resolution</th><th>ID</th></tr></thead><tbody><tr><td><p>Build failures caused by an incorrectly published <code>pom.xml</code> in Exchange for HTTP Connector 1.11.2 are now fixed.
