# Webhooks

Webhooks can send messages to a text channel without having to log in as a bot. They can also fetch, edit, and delete their own messages. There are a variety of methods in discord.js to interact with webhooks. In this section, you will learn how to create, fetch, edit, and use webhooks.

# What is a webhook

Webhooks are a utility used to send messages to text channels without needing a Discord application. Webhooks are useful for allowing something to send messages without requiring a Discord application. You can also directly edit or delete messages you sent through the webhook. There are two structures to make use of this functionality: Webhook and WebhookClient. WebhookClient is an extended version of a Webhook, which allows you to send messages through it without needing a bot client.

# Detecting webhook messages

Bots receive webhook messages in a text channel as usual. You can detect if a webhook sent the message by checking if the Message.webhookId is not null. In this example, we return if a webhook sent the message.

if (message.webhookId) return;

If you would like to get the webhook object that sent the message, you can use Message#fetchWebhook()open in new window.

# Fetching webhooks

# Fetching all webhooks of a guild

If you would like to get all webhooks of a guild you can use Guild#fetchWebhooks()open in new window. This will return a Promise which will resolve into a Collection of Webhooks.

# Fetching webhooks of a channel

Webhooks belonging to a channel can be fetched using TextChannel#fetchWebhooks()open in new window. This will return a Promise which will resolve into a Collection of Webhooks. A collection will be returned even if the channel contains a single webhook. If you are certain the channel contains a single webhook, you can use Collection#first()open in new window on the Collection to get the webhook.

# Fetching a single webhook

# Using client

You can fetch a specific webhook using its id with Client#fetchWebhook()open in new window. You can obtain the webhook id by looking at its link, the number after https://discord.com/api/webhooks/ is the id, and the part after that is the token.

# Using the WebhookClient constructor

If you are not using a bot client, you can get a webhook by creating a new instance of WebhookClient and passing the id and token into the constructor. These credentials do not require you to have a bot application, but it also offers limited information instead of fetching it using an authorized client.

const webhookClient = new WebhookClient({ id: 'id', token: 'token' });

You can also pass in just a url:

const webhookClient = new WebhookClient({ url: 'https://discord.com/api/webhooks/id/token' });

# Creating webhooks

# Creating webhooks through server settings

You can create webhooks directly through the Discord client. Go to Server Settings, and you will see an Integrations tab.

If you already have created a webhook, the webhooks tab will look like this; you will need to click the View Webhooks button.

Once you are there, click on the Create Webhook / New Webhook button; this will create a webhook. From here, you can edit the channel, the name, and the avatar. Copy the link, the first part is the id, and the second is the token.

# Creating webhooks with discord.js

Webhooks can be created with the TextChannel#createWebhook()open in new window method.

channel.createWebhook('Some-username', {
	avatar: 'https://i.imgur.com/AfFp7pu.png',
})
	.then(webhook => console.log(`Created webhook ${webhook}`))
	.catch(console.error);

# Editing webhooks

You can edit Webhooks and WebhookClients to change their name, avatar, and channel using Webhook#edit()open in new window.

webhook.edit({
	name: 'Some-username',
	avatar: 'https://i.imgur.com/AfFp7pu.png',
	channel: '222197033908436994',
})
	.then(webhook => console.log(`Edited webhook ${webhook}`))
	.catch(console.error);

# Using webhooks

Webhooks can send messages to text channels, as well as fetch, edit, and delete their own. These methods are the same for both Webhook and WebhookClient.

# Sending messages

Webhooks, like bots, can send up to 10 embeds per message. They can also send attachments and normal content. The Webhook#send()open in new window method used to send to a webhook is very similar to the method used for sending to a text channel. Webhooks can also choose how the username and avatar will appear when they send the message.

Example using a WebhookClient:

const { MessageEmbed, WebhookClient } = require('discord.js');
const { webhookId, webhookToken } = require('./config.json');

const webhookClient = new WebhookClient({ id: webhookId, token: webhookToken });

const embed = new MessageEmbed()
	.setTitle('Some Title')
	.setColor('#0099ff');

webhookClient.send({
	content: 'Webhook test',
	username: 'some-username',
	avatarURL: 'https://i.imgur.com/AfFp7pu.png',
	embeds: [embed],
});

Try to find a webhook your bot knows the token for. This makes sure your bot can execute the webhook later on.

const { Client, Intents, MessageEmbed } = require('discord.js');
const { token } = require('./config.json');

const client = new Client({ intents: [Intents.FLAGS.GUILDS] });

const embed = new MessageEmbed()
	.setTitle('Some Title')
	.setColor('#0099ff');

client.once('ready', async () => {
	const channel = client.channels.cache.get('123456789012345678');
	try {
		const webhooks = await channel.fetchWebhooks();
		const webhook = webhooks.find(wh => wh.token);

		if (!webhook) {
			return console.log('No webhook was found that I can use!');
		}

		await webhook.send({
			content: 'Webhook test',
			username: 'some-username',
			avatarURL: 'https://i.imgur.com/AfFp7pu.png',
			embeds: [embed],
		});
	} catch (error) {
		console.error('Error trying to send a message: ', error);
	}
});

client.login(token);

# Fetching messages

You can use Webhook#fetchMessage()open in new window to fetch messages previously sent by the Webhook.

const message = await webhookClient.fetchMessage('123456789012345678');

# Editing messages

You can use Webhook#editMessage()open in new window to edit messages previously sent by the Webhook.

const message = await webhook.editMessage('123456789012345678', {
	content: 'Edited!',
	username: 'some-username',
	avatarURL: 'https://i.imgur.com/AfFp7pu.png',
	embeds: [embed],
});

# Deleting messages

You can use Webhook#deleteMessage()open in new window to delete messages previously sent by the Webhook.

await webhookClient.deleteMessage('123456789012345678');
