Services
Redmine API Integration & Third-Party Integrations
Connect Redmine with the systems and apps your business already relies on.
How I can help
Redmine works best when it’s connected to the tools your team and customers already use. I build integrations and REST APIs that move data in and out of Redmine reliably — from chat and email to SMS, AI and mobile apps.
Integrations are built as Redmine plugins with their own settings, so credentials and behaviour are managed from Redmine’s administration.

Which systems have you integrated with Redmine?
Google Chat, OpenAI, Google Gemini, Microsoft 365 and Gmail email (OAuth2), Twilio SMS, and custom REST APIs for external and mobile applications, including timesheet APIs.
