Hello everyone,  
Using WebDev, I’ve to respond to a callback and the server accept only a code 204 No Content as a response. It seems that webdev answer 200 by default if there is nothing return.  
How can I do that?  
Many thanks

You should be able to do it directly with the servletResponse from the request, hinted at [in the manual](https://docs.inductiveautomation.com/display/DOC79/Web+Dev#WebDev-RequestParameter). You must return `None` to prevent normal handling of a webdev dictionary response.

Something like this:

```auto
    response = request['servletResponse']
    response.status = 204
    return None

```

For those encountering this post in 2025, like I am now:  
It seems returning a dict does work.

Here I changed the code to 302 and returned a dict:

> **endpoint's code for reference**
>
> ```python
> def doGet(request, session):
> tag_paths = [
> "[System]Gateway/Redundancy/IsMaster",
> "[System]Gateway/Redundancy/IsActive"
> ]
> is_master, is_active = [qv.value for qv in system.tag.readBlocking(tag_paths)]
> 	
> if not is_active:
> request['servletResponse'].status = 302
> 	
> return {
> 'json': {
> 'is_master': is_master,
> 'ip_addr': system.net.getIpAddress(),
> 'hostname': system.net.getHostName()
> }
> }
>
