Daily Coinbase Portfolio Report to Telegram (n8n CDP JWT)

Get your Coinbase Advanced Trade portfolio total every morning in Telegram

This n8n workflow automatically pulls your Coinbase Advanced Trade account balances using CDP JWT (ES256), values each holding in your chosen quote currency, and sends a clean HTML portfolio report (including change since the last run) to Telegram.

What this workflow does

• Runs daily at 8:00 via an n8n schedule.
• Authenticates with Coinbase CDP JWT: signs a short-lived ES256 JWT using your Coinbase CDP key and fetches account balances from the Coinbase Advanced Trade API.
• Filters & prepares holdings: keeps only non-zero holdings and treats quote-pegged currencies (e.g., USD/USDC) as a 1:1 value for pricing.
• Prices your assets: signs a second JWT, requests the best bid/ask pricebooks for required product pairs (example: BTC-USD), and calculates per-asset values.
• Computes totals & change: sums the portfolio value in the configured quote currency and compares it to the previous run using stored workflow static data.
• Sends the report to Telegram as an HTML-formatted message to your configured chat/channel.

Use cases

• Daily visibility into a Coinbase Advanced Trade portfolio without checking the exchange manually.
• Tracking performance for founders/operators who need quick portfolio change alerts.
• Building an operational “at-a-glance” dashboard using Telegram for investors, analysts, or personal finance monitoring.
