Discord Webhook

Want to have a notification in a discord server for when your pack is updated, so people can manually download it and use something like Server Resourcepack Checker to join the server without needing to wait for Minecraft to reload resources?

Would you look at that, a fully customizable webhook system with even a preset for discord messages!? Perfect!

Ok let's talk about how it works...

Explanation

You may have noticed the webhookUrl and webhookBody config options from earlier in the Mod Configuration section.
Those aren't for a webhook that the mod receives. Instead, they're for a webhook sent after a pack update is completed.

How does that work you ask?

Well the webhookUrl should be pretty self-explanatory, it's the url that the webhook will be sent to.
For example a discord webhook such as https://discord.com/api/webhooks/1234567890123456789/eW91J3JlIG5vdCBzdGVhbGluZyBhIHRva2Vu_bm9wZQ==_eWVyJyBub3Q= or something custom like https://api.service.com/NDI6IHRoZSBtZWFuaW5nIG9mIGxpZmUsIHRoZSB1bml2ZXJzZSwgYW5kIGV2ZXJ5dGhpbmc=

The webhookBody may seem a bit complicated, but I swear it's not. It's just a relative path from the config directory to a webhook body file. Got all that?
Have you noticed the basic_webhook.json file and discord directory next to the main config file? Those are webhook body files!
Take a look at the discord/basic_message.json file:

{
    "username": "GitHub Resource Pack Manager",
    "avatar_url": "https://github.com/OffsetMods538/Github-Resourcepack-Manager/blob/master/src/main/resources/assets/github-resourcepack-manager/icon.png?raw=true",
    "content": "New update for pack released!\nDescription: {shortDescription}\nDownload [here]({downloadUrl})"
}

This exact json will be sent to the webhook url provided in the main config, just with the placeholders replaced.
That is the great part of the webhook system: you can adapt it to send data to literally anything by creating a new body file and customizing it to your needs!

Usage

Let's actually set up messages like this on our discord server: Image showing an embed message sent by the mod though a webhook

Creating webhook

Right-click on the Discord channel you want to create a webhook for and select Edit Channel.
Next open the Integrations tab and press the Create Webhook button.
Now click on the webhook that Discord created for you, and then click Copy Webhook URL. You do not need to change any settings on this page.

Configuring the mod

Open the config file of the mod and set the webhookUrl to your discord webhook. Make sure it's in quotes.
Example: "https://discord.com/api/webhooks/1234567890123456789/eW91J3JlIG5vdCBzdGVhbGluZyBhIHRva2Vu_bm9wZQ==_eWVyJyBub3Q="

Then set the webhookBody to "discord/embed_message.json" (or "discord/basic_message.json if you're feeling basic today). Make sure this is also in quotes.

Last step is to modify the json file you chose. This is optional, but you probably don't want the name of the mod and the ugly logo I made for it as your bot.

Testing

Finally, you can try it out!
All you need to do is start up your server and try committing something to your repository. Everything should work!
