Connecting a Slack webhook to GitHub

Question

First of all, I'm not sure if this is the place to post this, but this is my last stop to get this fixed.

I've been trying to connect a Slack WebHook with a GitHub repository and I fail every time.

The steps I followed:

1. Create a webhook (both individually and using a new slack app) Copy
2. Copy the hook URL and paste in the new hook option in the GitHub repo.
3. Then when I create it, it gives me an error.

BTW, what should I add to the "Secret" field?

Please check the screenshot for more info.

Then I get the below error.

Let me know if I'm doing something wrong.

Looks to me that github uses its own format for the payload, which can not be configured and does not match Slack's format. Which I guess is why you get the error. But why do you not use the free Github Slack app instead? – Swept

Yes, I have tried the GitHub app and it didn't work. That's why I tried this option. Then after your response, I realized that I use GitHub Enterprise version and it doesn't support the GitHub app. There is a different version named GitHub Notifications (Legacy), and only that works for the enterprise version. The term "legacy" had misled me not to use it. Anyway, I got my requirement done using that app. Thanks for the tip. :) – Whirlwind

Also, there is no secret required to use the Slack webhook – Ammoniac

This "GitHub Notifications (Legacy)" is the only thing that worked for us. – Bonspiel

Looks like Github, left this for other tools to generate some income. Why is it so complex ? for Gitlab it's a walk over – Fir

Not sure if this is still valid, but as I am also trying to create this connection, I found a possible solution in the GH Marketplace: https://github.com/marketplace/actions/slack-webhook-for-github-actions
