Q Light Controller+

Hi everyone,

I’m currently working on a project that involves triggering scenes and controlling DMX fixtures in QLC+ using HTTP API calls. While the Web Interface (at http://<IP>:9999) works fine and I can use the Virtual Console buttons from the browser, I’ve run into issues with HTTP commands such as /api/functions and /run_scene.

Here’s what I’ve tried:
1. Enabled the Web Interface in QLC+ Network Settings.
2. Verified that the Web Interface loads successfully on the same computer and other devices on the network.
3. Attempted to call the following endpoints:
• http://<IP>:9999/api/functions – Results in a 404 error.
• http://<IP>:9999/run_scene?scene_name=Blue – Also results in a 404 error.
4. I tested port 9999 using other tools (e.g., telnet), and the Web Interface itself is accessible without issues.

My setup:
• QLC+ Version: 4.13
• Platform: Windows 11
• Web Interface Enabled: Yes


I’ve also tried different project files and restarted QLC+ to ensure the scenes are loaded properly. The test page provided with the QLC+ Web Interface (which uses WebSockets) works as expected, but the HTTP endpoints seem to be non-functional.

So, my questions are:
1. Are HTTP API calls (e.g., /api/functions, /run_scene) supported in the latest version of QLC+?
2. If yes, is there any additional configuration required to enable them?
3. Are there alternative ways to trigger scenes using HTTP or similar protocols?

Any guidance or clarification would be greatly appreciated. I want to confirm if I’m missing something or if the HTTP functionality is not implemented.

Thanks in advance for your help!

Escuse me but what are you talking about??
There's no such /api/functions or run_scene. Where did you get that from?
The official web API is documented here
https://docs.qlcplus.org/v4/advanced/web-interface
and test page is here
https://www.qlcplus.org/Test_Web_API.html

What you describe has not been implemented by this project. So I'm wondering who directed to something that we cannot support here...

Massimo, maybe he asked to ChatGPT an get wrong responses.

This is exactly what happened! I've worked out another route to do what I need. There are some great features of this software and learning something new every time I use it!

So you're basically telling us that you asked an AI for something, didn't verify the answer, came straight here to request support and abused of our time.
Guys...brain ON, chatGPT OFF please

Massimo, some new generation tech guys ask everything to ChatGPT. Sometimes the responses works but sometimes not. I used ChatGPT for specific cases and I get good responses many times the code proposed by AI don't work.
Claran please RTFM.

Santiago, I use it too, but I always verify the answer which most of the times is disappointing and needs to be fixed.
In general it saves time for specific tasks (especially for developers) but 90% of the times you need 3-4 iterations to get a response that makes sense
