Hi @mpadvisory, Are you posting to the slack compatible webhook endpoint?

I have copied the Discord API webhook endpoint, hopefully it is the correct one. For example, the last webhook attempted was: https://discord.com/api/webhooks/1001121069937201202/lfnXAd1JlIscyerDlV_NpiBgRZJm_fK-ItmApJRbogATDrBhqY_oqYhNIdJD3v82K4fY
