Discord Webhooks

Send messages to webhooks on Discord. If you do not want to use discordgo specifically for webhooks, this is a lightweight library that will allow you to send them.

Initalizing a Webhook Client

The library has two ways of initializing a webhook client. Unlike discordgo, you can also initalize a webhook client from its URL and not just from its ID and Secret.

ID + Secret

package main

import (
    webhooks "github.com/typical-developers/discord-webhooks-go"
)

func main() {
    id := "0"
    secret := "0"
    client := webhooks.NewWebhookClient(id, secret)
}

URL

package main

import (
    webhooks "github.com/typical-developers/discord-webhooks-go"
)

func main() {
    url := "https://discord.com/api/webhooks/0/0"
    client := webhooks.NewWebhookClientFromURL(url)
}

Executing Webhooks

Messages can be sent through webhooks using the Execute method on the client.

Sending Messages

package main

import (
    "context"

    webhooks "github.com/typical-developers/discord-webhooks-go"
)

func main() {
    ctx := context.Background()

    url := "https://discord.com/api/webhooks/0/0"
    client := webhooks.NewWebhookClientFromURL(url)

    _, _, err := client.Execute(ctx,
        webhooks.MessagePayload{
            Content: "Hello World!",
        },
        nil,
    )
    if err != nil {
        panic(err)
    }
}

Sending Messages with Files

package main

import (
    "context"

    webhooks "github.com/typical-developers/discord-webhooks-go"
)

func main() {
    ctx := context.Background()

    url := "https://discord.com/api/webhooks/0/0"
    client := webhooks.NewWebhookClientFromURL(url)

	file, err := os.Open("file.png")
    if err != nil {
        panic(err)
    }
    defer file.Close()

    _, _, err := client.Execute(ctx,
        webhooks.MessagePayload{
            Content: "Hello World!",
            Files: []webhooks.WebhookFile{
                webhooks.WebhookFile{
                    FileName: file.Name(),
                    Reader:   file,
                },
            },
        },
        nil,
    )
    if err != nil {
        panic(err)
    }
}

Waiting for Response

Adding a wait=true query parameter will allow you to wait for the webhook to send and the server to acknowledge it. This will return a WebhookMessage, which adds methods that allow you manage the message. You must ensure that the returned message is not nil before attempting to call any of the methods associated with it. 204 No Content can result in a nil message.

package main

import (
    "context"
	"net/url"

    webhooks "github.com/typical-developers/discord-webhooks-go"
)

func main() {
    ctx := context.Background()

    u := "https://discord.com/api/webhooks/0/0"
    client := webhooks.NewWebhookClientFromURL(u)

    query := url.Values{}
    query.Set("wait", "true")

    message, _, err := client.Execute(ctx,
        webhooks.MessagePayload{
            Content: "Hello World!",
        },
        &query,
    )
    if err != nil {
        panic(err)
    }

    if message != nil {
        _, _, err := message.Edit(ctx,
            webhooks.EditMessagePayload{
                Content: "Hello World, but edited!!",
            },
            nil,
        )
    }
}
