Forward URL per device
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.xmlsetforward.urlblank 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.
@SwayDev as your say json support per device forward how can I do this can I forward each device to different different endpoint.
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>
