By default Windows doesn't display the notifications in the notification center. You can enable this by doing the following steps.

1. Go to 'notifications & actions settings' (Windows key, type 'notifications', enter)
2. Click on the 'toast' app at the bottom of the screen.
3. Enable the 'show in action center' checkbox.

1. Open a Telegram chat with BotFather.
2. Follow the instructions to create your own bot.
3. Copy the token and enter it in the configuration via backmarket-watcher config, and set enabled to true.
4. Start the application backmarket-watcher watch
5. Click the t.me/BOTNAME link from the BotFather chat message.
6. Press BEGIN.
7. Your bot should greet you, and show a notification about your products. Note: the bot will show the products which you configured. Multiple people can connect to the bot to get updates about these products.

1. Go to https://ifttt.com/create/.
2. Click on this and select Webhooks.
3. Fill in an Event Name (e.g. backmarket_updated).
4. Click on that.
5. Select anything you'd like to integrate with (e.g. Philips Hue).
6. Finish setting it up. Note: value1 contains a plain text message, value2 contains an HTML message.
7. Update the ifttt configuration via backmarket-watcher config:
   • set enabled to true
   • set webhookKey to the token found at Web Hook settings (last part of the URL)
   • add the Event Name selected in step 3 to the webhookEvents array

Note: You can add multiple events to webhookEvents

Note: the Docker image is a multiarch image. So it will also work on Raspberry Pi's.

1. Create a directory to store the config file and copy the config.defaults.json into YOUR_FOLDER/config.json. See above for instructions on how to configure the application. Make sure that the folder has the correct permissions, e.g. run chmod -R o+rwx config/ or you might get access denied errors on the file system. The app needs read/write access on the configuration file, e.g. to store token received in it.
2. Run the following command. Example: a user john who stored the config in ~/docker/backmarket-watcher/config.json:

docker run \
 --name backmarket-watcher \
 -e TZ=Europe/Amsterdam \
 -v /home/john/docker/backmarket-watcher:/home/node/.config/backmarket-watcher-nodejs \
 youegraillot/backmarket-watcher

Note: When using Gotify as notification, make sure to put them on the same network in docker if hosted on the same docker host, e.g. docker network create gotify and use "--network=gotify" on both containers You can then use "http://gotify" on this container if --name gotify is used for the gotify container

1. Create a directory to contain all your Docker Compose things.
2. Create a directory backmarket-watcher inside the created directory, and copy the config.defaults.json to backmarket-watcher/config.json. See above for instructions on how to configure the application.
3. Create a file docker-compose.yaml:

version: "3"
services:
  backmarket-watcher:
    image: youegraillot/backmarket-watcher
    restart: unless-stopped
    environment:
      - TZ=Europe/Amsterdam
    volumes:
      - ./backmarket-watcher:/home/node/.config/backmarket-watcher-nodejs

1. Install the Heroku CLI and login.
2. From your terminal, run heroku config:set BACKMARKET_CONFIG=content, replacing content with the content of your config.json file.
