Forward URL per device

Cristiana month ago

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.

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?

Anton Tananaeva month ago

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>

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

Cristiana month ago

Understood Anton, I did not handle that information.

I made the following change

But nothing happens

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

Cristiana month ago

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.
