Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.8.3

Ollama Version (if applicable)

No response

Operating System

Ubuntu 24.04

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

From the docs, https://docs.openwebui.com/reference/api-endpoints/

The example request:
curl -X POST http://localhost:3000/api/responses -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{"model": "gpt-4.1","input": "Explain quantum entanglement in simple terms."}'

This should work as intended and return a response.

Actual Behavior

You get an {"detail":"Method Not Allowed"}

Steps to Reproduce

Deploy latest docker version of open-webui
Grab API key for user account
Following API docs instructions.

Logs & Screenshots

open-webui | 2026-02-19 13:26:44.827 | INFO | uvicorn.protocols.http.httptools_impl:send:483 - :0 - "POST /api/responses HTTP/1.1" 405

Additional Information

Solution is to use http://localhost:3000/openai/responses, but this is contrary to what the docs say. Likely need an routing alias so that api/responses work.
