Description: A Jenkins webhook is a tool that allows Jenkins jobs to be triggered in response to specific events occurring in other services. This functionality is based on the concept of ‘events’ and ‘notifications’, where an external service sends an HTTP request to Jenkins when a relevant event occurs, such as a push to a code repository. This enables more efficient continuous integration, as Jenkins can react immediately to code changes rather than relying on a fixed execution schedule. Webhooks are especially useful in agile development environments, where code changes are frequent and rapid feedback on software quality is required. Additionally, webhooks can be configured to send additional information about the event, allowing Jenkins to make more informed decisions about how to proceed with the job. In terms of configuration, webhooks are easy to implement and can be managed through the Jenkins user interface or via configuration as code scripts, allowing for greater automation and control over the continuous integration process.
