Coinsentry Crypto Webhook to Google Sheets & Telegram (n8n)

Turn Coinsentry crypto alerts into live Google Sheets logs and Telegram notifications (n8n)

This n8n workflow receives signed Coinsentry webhook events for crypto exchange listings and delistings, verifies the HMAC signature for security, then automatically appends each valid event to Google Sheets and posts a formatted update to Telegram.

What this workflow does

• Receives a POST webhook from Coinsentry containing a listing or delisting payload.
• Verifies authenticity with HMAC-SHA256: the workflow recomputes the signature from the raw request body and compares it to the x-coinsentry-signature header to reject unsigned or tampered requests.
• Filters supported event types, allowing only listing_announced, listing_live, and delisting.
• Extracts and formats key fields including timestamp, event, exchange, symbol, pairs, trading start time, and source URL for clear notifications.
• Appends a new row to your selected Google Sheets worksheet (matching your column mapping).
• Sends a Telegram message to your configured chat with the headline and any available pair/start-time/source details.

Use cases

• Maintain an always-up-to-date listings/delistings tracker for multiple exchanges in Google Sheets.
• Alert your team instantly via Telegram when Coinsentry detects listings announced, listings going live, or delistings.
• Support operational workflows for SaaS teams that need reliable, verifiable webhook ingestion and audit-friendly logging.

Technical details

• Nodes/logic used: webhook, crypto (HMAC-SHA256 verification), if, set, and a no op step where applicable, plus telegram and Google Sheets append.
• Security: HMAC verification against the x-coinsentry-signature header.
• Setup requirements: configure a Coinsentry webhook channel with a signing secret, provide the same secret in an n8n Crypto credential, connect Google Sheets (select spreadsheet + sheet), and set up Telegram credentials and chatId.
