How can I secure my Slack webhooks?

To secure your Slack webhooks, you can use a few strategies such as validating incoming requests, using secret tokens, and restricting IP addresses.

What do you mean by validating incoming requests?

Validating incoming requests means checking that the requests to your webhook are actually coming from Slack. You can do this by verifying the request signature.

How do I implement request signature verification?
