Forward URL per device

One query, to use the forwarding URL per device the following key must be present in the XML file:

<entry key='forward.enable'>true</entry>

Where did you get this information from?

I have reviewed several old threads.
What I am trying to do is to use the following option.

but without success

You have to set a URL in the configuration file, if I remember correctly.

I believe currently per device forward is only supported for JSON type.

traccar.xml Configuration

<entry key='forward.type'>json</entry>  
<entry key='forward.retry.enable'>true</entry>  
<entry key='forward.url'>https://webhook.example.com/position</entry>  

In the traccar.xml set forward.url blank if you don't want all device data to be forwarded.

Device Configuration

All good now?

the tests I performed showed these errors.

using the example, here I had to add port 5055 otherwise it did nothing.

<entry key='forward.url'>https://webhook.example.com/position</entry>

What version of Traccar are you using?
The URL you have configured are they valid and working?

No route to host

This means your URL is unreachable.

I am working with Traccar 6.6

if I do the following, the Traccar demo server receives the information

http://demo.traccar.org:5055/?id=201643&lat=-33.01951&lon=27.90384&altitude=57&speed=36.198704103671705&blocked=false

configuration in the XML file

    <entry key='forward.type'>json</entry>
    <entry key='forward.retry.enable'>true</entry>
    <entry key='forward.url'></entry>

configuration on the device

I'm kind of confused. Are you expecting this to work? Port 5055 doesn't accept JSON.

Understood Anton, I did not handle that information.

I made the following change

But nothing happens

2025-03-24 12:50:29  INFO: [T4e9f7811] id: 201643, time: 2025-03-24 12:50:28, lat: -38.98003, lon: -72.63799, course: 0.0, accuracy: 100.0

That makes even less sense because this URL doesn't exist.

Ah ok, then I give up, keep trying, it's like playing guessing games to find the solution, thanks to all of you.
