Forward url

I am trying to forward traccar gps data to my callback url from config file like below:

<entry key='event.forward.enable'>true</entry>-->
<entry key='event.forward.url'>http://192.168.1.6/traccar?id={uniqueId}&amp;deviceId={deviceId}&amp;valid={valid}&amp;fixTime={fixTime}&amp;deviceTime={deviceTime}&amp;protocol={protocol}&amp;name={name}&amp;latitude={latitude}&amp;longitude={longitude}&amp;altitude={altitude}&amp;speed={speed}&amp;attributes={attributes}</entry>

And I get the following error

INFO: [Tc2479c42] error - The template variable 'uniqueId' has no value - IllegalArgumentException (... < EventForwarderJson:41 < NotificationManager:141 < *:83 < *:155 < ConnectionManager:247 < ...)

Where did you get this configuration from?

Hi Anton,
I found an example in one forum post and tried to send custom data to my url
https://www.traccar.org/forums/topic/are-there-server-hooks/#post-1934

If I do not specify parameters in url it forward data but not device attributes and coordinates

The configuration parameters are completely different in that post.

Here is my config file

 <entry key='forward.enable'>true</entry>
 <entry key='forward.url'>http://192.168.89.239:3001/traccar/Data?id={uniqueId}</entry>

and the log

 WARN: Position forwarding failed: 0 pending - HTTP code 404 - RuntimeException (PositionForwarderUrl:74 < *:67 < ...)

As you hopefully can see, your URL is returning error 404.

Hi Anton,

with this configuration

 <entry key='forward.enable'>true</entry>
 <entry key='forward.url'>http://192.168.89.239:3001/traccar/Data</entry>

I am able to get this data, but when I enter parameters like id, lat, lon, or any other I get:

error - The template variable 'lat' has no value - IllegalArgumentException (... < EventForwarderJson:41 < NotificationManager:141 < *:83 < *:155 < ConnectionManager:247 < ...)

{
  event: {
    id: 9495,
    attributes: {},
    deviceId: 5,
    type: 'deviceOnline',
    eventTime: '2024-04-22T07:21:25.966+00:00',
    positionId: 0,
    geofenceId: 0,
    maintenanceId: 0
  },
  device: {
    id: 5,
    attributes: {},
    groupId: 0,
    calendarId: 0,
    name: 'E-mak',
    uniqueId: '864636061378788',
    status: 'online',
    lastUpdate: '2024-04-22T07:21:25.966+00:00',
    positionId: 90419,
    phone: null,
    model: null,
    contact: null,
    category: null,
    disabled: false,
    expirationTime: null
  }
}

This is not your configuration. The error is with event forwarding, which means you provided incorrect information.

This is config.xml

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE properties SYSTEM 'http://java.sun.com/dtd/properties.dtd'>

</properties>

and the webhook is a simple js function to parse url and body. I would appreciate your suggestion.
