Webhooks Demo #CEsri20

We finally have Webhooks also supported on hosted feature services! ^_^

This is a short tutorial on how to reproduce the same demo we did at the Developer's Week during the Esri Spain User Conference in 2020.

Requirements: you need to have installed: Git, NodeJS and ngrok in your computer

Tutorial

To reproduce this example:

1. Run this script:

   • Clone this repo: https://github.com/esri-es/webhooks-demo-cesri20.git
   • Install dependencies: npm i
   • Run: node index.js

2. Run grok http 127.0.0.1:3000 in a different terminar

3. Setup your Webhook

   • Create a new Hosted Feature Layer
   • Click "View in ArcGIS Online" > "Settings", and check "Keep track of created and updated features"
   • Get a token from: https://developers.arcgis.com/dashboard
   • Get your service URL, add "admin/" between "rest" and "services" and also add at the the "?token=<YOUR TOKEN>"
   • Click on "Web Hooks" (bottom right) > "Create" and add
     • Change types: *
     • HookURL: <your ngrok url, something like https://ba3d5b9bf39c.ngrok.io>
     • Click create

Now you are ready to test it:

• Open the Web Map Viewer
• Sign in
• Load the feature layer
• Do some edits
• And wait until you start seeing messages in your console ^_^

Known limitations

This script do not support secured services but contributions are always welcome. We would suggest to use arcgis-rest-js to make it easy.
