Webhook is a lightweight automation server that executes local shell scripts and system commands in response to incoming HTTP requests. It functions as an integration engine, mapping external network events to server-side tasks by parsing request payloads and triggering predefined processes.
The project distinguishes itself through a declarative configuration model that allows for dynamic argument injection. By extracting values from request headers, query parameters, or bodies, it populates command templates to facilitate flexible script execution. This enables the automation of infrastructure workflows, such as deployment pipelines, by bridging external service events with local command-line operations.
Security is managed through request signature validation, which verifies the authenticity of incoming payloads against stored secrets before any command execution occurs. The system operates by spawning synchronous child processes, capturing their output to provide immediate feedback for each request. The software is distributed as a standalone binary and is configured via structured files.
