Section titled WebhooksWebhooks

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.

Section titled What is a webhookWhat 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.

Section titled Detecting webhook messagesDetecting 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 you would like to get the webhook object that sent the message, you can use Message#fetchWebhook().

Section titled Fetching all webhooks of a guildFetching all webhooks of a guild

If you would like to get all webhooks of a guild, you can use the Guild#fetchWebhooks() method. This will return a promise which will resolve into a collection of webhooks.

Section titled Fetching webhooks of a channelFetching webhooks of a channel

Webhooks belonging to a channel can be fetched using the TextChannel#fetchWebhooks() method. 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 the Collection#first() method on the collection to get the webhook.

Section titled Using clientUsing client

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

Section titled Using the WebhookClient constructorUsing 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.

You can also pass in just a url:

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.

Section titled Using webhooksUsing 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.

Section titled Sending messagesSending messages

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

Example using a WebhookClient:

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