**Hi everyone,**

I’m receiving LPR data in Ignition using a WebDev endpoint, and when I manually send JSON data using cURL to:

`http://<Ignition-IP>:8088/system/webdev/File_Transfer/LPR/receive`

Ignition receives the data correctly and stores it in PostgreSQL.  
So the WebDev script is working.

However, when I enter the same URL into the Milesight camera’s **HTTP Notification** settings, Ignition receives nothing—no logs in ignition, no errors, and no incoming POST requests. The camera _is_ capturing plates, but it looks like the camera is not triggering the Ignition URL.

In the Milesight documentation, the required format is:

`http://IP:Port/api/lpr`

I’m not sure how to map this requirement to Ignition’s WebDev path.  
Should the URL be rewritten or simplified so the camera will accept it?  
For example:

- `http://localhost:8088/api/lpr` → but this does not exist in Ignition

- [localhost:8088/system/webdev/File\_Transfer/LPR/receive](http://localhost:8088/system/webdev/File_Transfer/LPR/receive)`.` → camera seems to reject it

You cannot. You may need a reverse proxy in front of Ignition that silently proxies the URL.

Consider running wireshark to see exactly what URL the camera is trying to reach.
