Hi @Bruno Stroobants
Thank you for posting your question in the Microsoft Q&A forum.
Microsoft has announced upcoming changes to Power Automate flows that use HTTP or Teams Webhook triggers. Beginning August 2025, new trigger URLs will be introduced, and the existing *.logic.azure.com endpoints will be retired on November 30, 2025. After this date, any flows still pointing to the old domain will fail silently, HTTP requests and webhooks will be directed to a non-existent address, and your automations simply won’t run.
Currently, Microsoft has not published any official documentation indicating that the migration will be enforced earlier than planned. The official cutoff date remains November 30, 2025, with both the old and new trigger URLs expected to run in parallel until that time.
However, the rollout of the new URLs is being implemented gradually, region by region, so availability may vary depending on your location. Many other tenants have encountered the same issue, you may check it here 5532852 | Power Platform admin center.
To avoid disruption, all impacted flows should be reviewed, updated with the new URLs, and tested well in advance. Any external systems or integrations referencing the old URLs will also need to be updated.
Recommendation: Please do not wait until the deadline. Update your HTTP-triggered flows now to ensure continued reliability and uninterrupted automation.
