Creating a Discord webhook named after the product fails because the name contains discord

DiscordAPIError[50035]: Invalid Form Body on create webhook

Verified 2026-10-15 · Confirmed by 0 builders · Trust 50/100

Cause

Webhook names may not contain the substrings discord or clyde in any letter case. The rule is listed under Create Webhook, not under the username override on Execute Webhook.

Fix

Pick a name without those substrings and validate user-supplied names before calling the API.

Apply

if (/discord|clyde/i.test(name)) name = name.replace(/discord|clyde/gi, "").trim() || "Alerts";

Affects: Discord API v10 Create Webhook, as of 2026-10
