slackchannel? What is it job? about cloudflare-ddns-updater HOT 3 CLOSED

Thanks for queuing me in @K0p1-Git.

I haven't looked into this in-depth yet but I'll explore this more.

My initial answer:

To the best of my knowledge, I may be incorrect here but you basically create the app in slack, copy the webhook to the script and then add the app to the channel (that gives authorization to post in said channel). If you had the app added to multiple channels, I believe that's where the channel name designation matters.

I will look into this more on my spare time but that's my initial answer. Hope that somewhat answers your question.

Hey @northportio, if its possible do take a look at this.

@northportio Yep! You're correct however...(Hey! Just my two cents opinion down here)

Afaik, because of security scopes, Webhooks are usually tied to a specific channel. Each webhooks uri is unique, no matter the app, destination channel etc. (You can try create a duplicate webhook, and see that the request uri is different even thought they post to the same channel, from the same app etc)

To implement channel name designation, i think the following steps must be done.

An user needs to go to here. Create an app, and go to OAuth & Permissions, then setup the necessary OAuth permission scopes like channels:read for reading available channels, and chat:write for sending messages.

Then copy the bot user oauth token, it usually starts with xoxb-<...>.

Then post request code shall be like:

#!/bin/bash
slack_api_url="https://slack.com/api/chat.postMessage"
slack_app_token="your-bot-user-oauth-token-here"
slack_channel="general"

slack=$(curl -s -X POST $slack_api_url \
    -H "Authorization: Bearer $slack_app_token" \
    -H "Content-type: application/json; charset=UTF-8" \
    --data "{\"channel\":\"$slack_channel\",\"text\": \"Hello world! I'm sending message to $slack_channel channel.\"}")
