What is Redmine API?

Redmine API enables developers to build applications that interact with Redmine, automate workflows, and integrate Redmine with other systems, making it a powerful tool for project management and collaboration. The API allows performing CRUD (Create, Read, Update, Delete) operations on Redmine entities such as issues, projects, users, time entries, and custom fields. Usually, authentication is required to prevent unauthorized access, typically using an API key.

Easy Redmine, a commercial version of Redmine, also has an enhanced API for easy integration and data migration from third-party systems.
