Error in DeepL node
I created issue on GitHub: DeepL: Deprecation of query parameter and request body authentication · Issue #25304 · n8n-io/n8n · GitHub
and someone already fix it in PR: fix(DeepL Node): migrate authentication from deprecated query parameter to header-based auth by pierreeurope · Pull Request #25669 · n8n-io/n8n · GitHub
I just don’t understand, how long it takes to fix this, because I use DeepL node a lot, and I believe many users too. I’m writing here to get answer from support or people that face the same issue
What is the error message (if any)?
Forbidden - perhaps check your credentials?
Legacy authentication method ‘query parameter’ is no longer supported. Please update to header-based authentication. Find more details in our docs: https://developers.deepl.com/docs/resources/breaking-changes-change-notices/november-2025-deprecation-of-legacy-auth-methods.
