How can I customize Slack webhook messages?

You can customize Slack webhook messages by modifying the JSON payload you send to the webhook URL. What specific customizations are you looking for?

I want to change the message format and add some emojis.

You can change the message format by using the 'text' field in the JSON payload. To add emojis, you can use their Unicode or Slack's emoji codes. Would you like an example?

Yes, please provide an example of the JSON payload.

Here's a simple example: {"text": "Hello, world! :smile:"}. This will send a message with a smiley emoji. You can customize it further by adding attachments or blocks.
