LINE user ID, a 33-character random string, is crucial for bot development. Webhook enables data reception between servers. Set up a webhook URL in the LINE Developer Console to receive user interactions. Use webhook.site for testing without building a server. Send messages to your LINE Official Account to verify the setup.
Get LINE user ID is an important step in building a LINE bot. The user ID is a 33-character long random string, which is different from the ID that users set by themselves. LINE Developer: Get user IDs
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.
Using Webhook.site for testing LINE bot integrations is a great practical shortcut for developers. Bypassing local server deployment or ngrok setup just to capture the 33-character user ID payload saves valuable time during the initial proof-of-concept phase before writing actual webhook handling logic.
