/api/public/generations stops working
Stops working (in 24 days)
On November 16, 2026, the Langfuse API endpoint /api/public/generations will be removed. Calls made to /api/public/generations after this date will fail, as Langfuse Cloud serves these trace-ingestion paths only until November 16, 2026.
What to use instead of these calls
Send generations to POST /api/public/otel/v1/traces (OTLP/HTTP) with the x-langfuse-ingestion-version: 4 header, or upgrade your SDK to Python 4.7.0, JS/TS 5.4.0, or later.
