Error message

Discord webhook credential does not contain a webhook ID and token

What it means

After URL parsing and the HTTPS check, the uploader extracts the webhook ID and token from the path segment after `webhooks` and validates that the ID is numeric. If the path does not contain `/webhooks/<numeric-id>/<token>`, the credential is not a usable Discord webhook and this error is thrown.

Solutions

Use the full Copy Webhook URL: https://discord.com/api/webhooks/<numeric-id>/<token>
Verify both the numeric ID and token segments are present after /webhooks/ in the URL
Ensure you are not pasting a Slack or other-provider webhook URL into the discord destination
Recreate the webhook in Discord if the URL was truncated or the token was rotated

Example fix

// before (channel URL, not a webhook)
webhookUrl = https://discord.com/channels/1234567890/9876543210
// after
webhookUrl = https://discord.com/api/webhooks/1234567890/aBcDeFgHiJkLmNoP

Defensive patterns

Strategy: validation

Validate before calling

function extractWebhookIdAndToken(webhookUrl) {
  const url = new URL(webhookUrl);
  const segs = url.pathname.split('/').filter(Boolean);
  const i = segs.indexOf('webhooks');
  const id = i >= 0 ? segs[i + 1] : undefined;
  const token = i >= 0 ? segs[i + 2] : undefined;
  if (!id || !token || !/^\d+$/.test(id)) {
    throw new Error('URL is not a Discord webhook (need /webhooks/<numeric-id>/<token>)');
  }
  return { id, token };
}

Type guard

function isDiscordWebhookUrl(value) {
  if (typeof value !== 'string') return false;
  try {
    const url = new URL(value);
    const segs = url.pathname.split('/').filter(Boolean);
    const i = segs.indexOf('webhooks');
    return i >= 0 && /^\d+$/.test(segs[i + 1] ?? '') && segs[i + 2] !== undefined;
  } catch {
    return false;
  }
}

Try / catch

try {
  await publishToDiscord(blob);
} catch (err) {
  if (err.message.includes('webhook ID and token')) {
    logger.error('webhookUrl is not a Discord webhook URL — re-copy from Discord Integrations');
  } else {
    throw err;
  }
}

Prevention

Use the exact Copy Webhook URL from Discord, never a channel or API URL
Don't confuse Slack/other webhooks with Discord's /webhooks/<id>/<token> shape
Check the URL wasn't truncated by shell quoting or config escaping
Validate the /webhooks/<numeric-id>/<token> pattern before saving the credential

When it happens

Trigger: The credential is a valid https URL but its path lacks `webhooks` (e.g. a Discord channel or API URL), the ID or token segment is missing, or the ID is non-numeric (e.g. a webhook created via a guild template or an interaction endpoint ` interactions/<id>/... ` URL was pasted instead).

Common situations: Pasting a Discord channel invite or API URL instead of the webhook URL; using an incoming-webhook URL from Slack (which has a different path shape) in the discord destination; truncating the URL so the token is cut off; Discord's newer `?wait=` or extra-path variants pasted partially.
