Webhooks

Plate Recognizer lets you forward the inference results to a third party. Here are examples for how to use our webhook API.

Starting the Webhook Server

Here are some webhook server examples. Pick one of the options below.

  • Python and the standard library:

Start the server

python3 webhook_reader.py
  • Python and Flask:

Install flask

pip install Flask==1.1.2

Start the server

export FLASK_APP=app.py
export FLASK_DEBUG=1
python3 -m flask run -h 0.0.0.0 -p 8001
  • Javascript / Node:

Install dependencies

npm install

Start the server

node server.js
  • C# / .Net Framework v4.8:

Install this NuGet package required for MultiPart Parsing

PM> Install-Package HttpMultipartParser

Build Solution and Run WebhookReader.exe as a Console Application

Sending Data to the Webhook Server

  1. Find your machine local IP for example 192.168.0.206. You can use ifconfig to get it.
  2. Send an example webhook to the server. If it is running correctly, it should exit without an error.
docker run -e URL=http://MY_IP_ADDRESS:8001 platerecognizer/webhook-tester
  1. Configure the webhook on Platerecognizer.
    • In Stream, edit your config.ini, add the following to a camera: webhook_target = http://MY_IP_ADDRESS:8001/
    • For Snapshot, open Webhooks Configuration.

Integrations

  • Connect Stream to Home Assistant. This project uses Stream webhooks to send license plate data to a home automation server. Form there, it will send a notification.
