n8n Gumroad Sales Tracker: Google Sheets + Slack Daily Report

Automate your Gumroad daily sales reporting with an n8n workflow that logs to Google Sheets and posts to Slack

This n8n Gumroad Sales Tracker workflow pulls your most recent Gumroad sales every day, calculates total sales and revenue, appends the results to a Google Sheets Daily Stats tab, and sends the same summary to a configured Slack channel.

What this workflow does

• Runs on a daily schedule to keep your reporting up to date.
• Loads configuration values including googleSheetId, slackChannel, and gumroadLookbackDays (how many days of sales to review).
• Calls the Gumroad Sales API to fetch sales created after the calculated lookback date.
• Aggregates results into a daily summary containing:
  • Total sale count
  • Total revenue
• Appends a new row to the Daily Stats tab in Google Sheets with Date, Sales, and Revenue.
• Posts the same daily summary message to your specified Slack channel.

Use cases

• Keep a reliable daily revenue record for a Gumroad storefront without manual exports.
• Send founder-style sales updates to your team in Slack every day.
• Use the lookback window to capture late-arriving sales and maintain accurate daily stats in Google Sheets.

Technical details

• n8n nodes / building blocks: set, code, http request, google sheets, slack, and a sticky note.
• Gumroad authentication: Create a Gumroad access token and send it as the access_token query parameter via an n8n HTTP Query Auth credential.
• Google Sheets: Requires OAuth2 access and a spreadsheet with a Daily Stats tab containing Date, Sales, and Revenue columns.
• Slack: Uses Slack OAuth2; ensure the target channel exists and the bot has permission to post.

Update the configuration, confirm your schedule, and you’re ready to track Gumroad sales automatically—daily—across Google Sheets and Slack.
