Verified Paddle Sale Alerts to Slack, Discord & Telegram (n8n)

Get Verified Paddle Sale Alerts to Slack, Discord & Telegram—Using n8n

This n8n workflow securely receives Paddle webhooks, verifies the request authenticity with Paddle-Signature, and instantly sends transaction.completed net-earnings alerts to Slack, Discord, and/or Telegram via simple webhooks.

What this workflow does

• Receives Paddle webhook events through an n8n webhook endpoint (with the raw request body enabled).
• Verifies authenticity by validating the Paddle-Signature header using HMAC-SHA256 over ts:rawBody with your Paddle notification secret (blocking forged requests).
• Filters events to process only transaction.completed and ignores other Paddle notifications.
• Formats a readable alert using Paddle transaction totals (total, fee, earnings, currency), including correct handling for zero-decimal currencies.
• Sends the same alert message to:
  • Slack via an incoming webhook
  • Discord via a channel webhook
  • Telegram using the Bot API sendMessage endpoint

Use cases

• Send real-time payout visibility to a support or finance channel whenever Paddle confirms a completed sale.
• Monitor revenue/earnings from subscriptions and one-time payments without logging into Paddle.
• Notify stakeholders in the tool they use most—Slack for ops, Discord for teams, Telegram for on-the-go updates.
