What Is Webhook?
Webhook is a way to receive data from one server to another server. In the LINE Developer Console, you can set up a webhook URL. When a user adds your LINE Official Account as a friend or sends a message, the webhook will receive the message and send it to your server.
Theoretically, you need to build a server to receive the webhook data. Luckily, we can use webhook.site to test the webhook.
Use Webhook.site To Get User ID
On webhook.site, you can get a webhook url. Copy and paste the url into the LINE Developer Console then verify the URL. Once the URL is verified, you can start to send a message to your LINE Official Account and check the webhook data.
If everything is set up correctly, you will see the similar webhook event in the webhook.site.
