Montoya API for Burp Suite Extensions

For detailed technical specifications and practical implementation patterns, refer to the following resources:

• Javadoc: Comprehensive API reference for all Montoya classes and methods.
• Examples Repository: A collection of practical extension examples to demonstrate various use cases.

To build Burp Suite extensions (BApps) using the Montoya API, add the following dependency to your build configuration. Ensure you use the version compatible with your target Burp Suite environment.

### Maven
```xml
<dependency>
    <groupId>net.portswigger.burp.extensions</groupId>
    <artifactId>montoya-api</artifactId>
    <version>2026.7</version>
</dependency>

Gradle

implementation 'net.portswigger.burp.extensions:montoya-api:2026.7'

To create a new extension, you must implement the BurpExtension interface. The entry point for your extension is the initialize method, which provides an instance of MontoyaApi. This MontoyaApi instance is the primary gateway for interacting with and modifying Burp Suite's functionality.

import burp.api.montoya.BurpExtension;
import burp.api.montoya.MontoyaApi;

public class MyExtension implements BurpExtension {
    @Override
    public void initialize(MontoyaApi api) {
        // Use the api instance to interact with Burp Suite
    }
}
