Why RowSink
It keeps the workflow simple: send data in, let the sheet adapt to new fields, and keep everything in Google Sheets.
Handles changing fields
Send JSON as it is. RowSink derives columns from incoming keys so the sheet can adapt as your payload changes.
Data stays in your sheet
Rows are written to your Google Sheet. The spreadsheet stays yours, and spreadsheet content is not stored by RowSink.
Works with Claude, Cursor, and Gemini
If you vibe code, give your AI agent the RowSink URL and tell it to send a POST request. The integration is plain HTTP, so agents and scripts can write rows without extra infrastructure.
Starter prompts
Tell your AI agent what to send
Two typical prompt patterns: one for app events, one for incoming webhooks.
Pattern 1
Log Every Signup
After a user signs up, POST their email, timestamp, and referral source as JSON to {ENDPOINT_URL}. Don't block the UI; fire and forget.
Pattern 2
Webhook Logger
When Stripe sends a successful payment event, POST the payment payload as JSON to {ENDPOINT_URL}. Return 200 OK immediately.

Plain HTTP
The same request works in code
If you prefer writing the request yourself, use the same endpoint and send the payload directly over plain HTTP.

Demo
Try it yourself
The demo sends a real POST request, gives you a demo ID, and shows the row in a real sheet.
