Webhook Events


eDRV provides developer applications a near real time stream of network wide events via Webhooks. We highly recommend developers use Webhooks to listen for events instead of polling for data.

Available Event Types

Currently eDRV reports events of the following types:

  • users
  • chargestations
  • connectors
  • commands
  • transactions


Event Data

For further information on each event type and the data fields, see the API Reference and Data Hierarchy

Use Cases

Some of the possible use cases for Webhooks are:

  • Build No-Code applications: Connect your EV charging network to thousands of other apps via Zapier and IFTTT. See Zapier Incoming Webhooks
  • Integrate with Mapping providers: Report the availability of your chargestations in real time to drivers
  • Onboard Users: Send a welcome set of emails helping Users who have just registered on eDRV
  • Smart Charging: Build intelligent power management applications for EV charging and react in real time to upstream power congestion. See Real Time Transaction Power Management
  • Reservation Systems: Use real time connector status events to build a queueing system for drivers in real time.

Subscribe to Webhooks

Navigate to the edrv dashboard > Integrations page. Add a new Webhook and paste your application's Webhook handler endpoint. eDRV will post all event types to this URL as an HTTP POST request.

Expected Response

Your application servers must respond to each request with

  • 200 OK status code
  • Empty response Body


No response or other errors

If there is continuously no response from your application or there are other errors in the POST request, eDRV will automatically disable your Webhook

Processing Webhook Data

The Webhook Body contains the following fields that your application must handle:

collection string

Reports event type. See Event Types above.

operation string

Event trigger. Can be one of the following:
create: Newly created e.g. when a User signs up for the first time
update: For e.g. with the connector state changes from "charging" to "available"

    "operation": "update",

Demo Webhook Server

As Webhook server in Node.js with some examples on how you can process the data delivered by eDRV within your application.

var express = require('express');
var app = express();
const port = 3000;

app.listen(port, () => {
  console.log(`Listening on port: ${port}`)

app.route('/').get(function (req, res) {
  res.send('Sample Webhook Handler');

app.route('/webhook').post(function (req, res) {
  //Immideately respond to eDRV servers

  //Process webhook data
  let data = req.body;
  switch (data.collection) {
    case 'connectors':
      if (data.operation === "update") {
        console.log(`New connector state is: ${data.document.status}`)
        //New connector state is: Preparing
      //Process other connector operations
    case 'users':
      //Process user data
    case 'chargestations':
      //Process chargestation data
    case 'commands':
      //Process commands
    case 'transactions':
      //Process transactions
      console.error(`Sorry, unrecognized event type: ${data.collection}.`);


Quick View

If you want to quickly test Webhook data received you may consider a disposable Webhook url from a service like Webhook.site.

Remember to delete your disposable webhook from the eDRV dashboard after you have tested it.
