How to Turn Your Google Sheet Into a Webhook Endpoint in 5 Minutes

Your contact form just got its first submission. Your IoT sensor is spitting out readings. Your automation tool is firing events. Now what? You need somewhere for that data to land—and you don't want to spend the afternoon wiring up a database.

Here's the shortcut: turn your Google Sheet into a live endpoint. One URL. Any JSON or form data. Rows appear automatically. No server, no migrations, no deployment.

Step 1: Create a Google Sheet

New sheet or existing—doesn't matter. Leave it blank if you like; RowSink creates columns from your first payload. Or add headers yourself and we'll match them.

Step 2: Share It With RowSink

In Google Sheets, click Share. Add the RowSink service account email as Editor. (You'll see this email when you connect the sheet—it's a one-click copy.) That's it.

Step 3: Connect and Get Your URL

Sign in to RowSink, paste your spreadsheet URL or ID, pick the tab you want, and hit Connect. You'll get a URL that looks like this:

https://api.rowsink.com/v1/spreadsheets/your-uuid/rows

That's your endpoint. Everything you POST to it becomes a new row.

Step 4: Send Data

Use curl, fetch, a form, or any HTTP client. Send JSON:

curl -X POST https://api.rowsink.com/v1/spreadsheets/YOUR_UUID/rows \
  -H "Content-Type: application/json" \
  -d '{"name":"Alice","email":"alice@example.com","message":"Hello!"}'

Or form data. Columns are created automatically from your keys—and new keys in later requests add new columns on the fly.

What You Can Do With This

• Contact forms: Point your form's action to the URL. No backend needed.
• Zapier, Make, n8n: Send any trigger to your sheet.
• IoT devices: POST sensor readings straight from the device.
• Prototypes: Collect test data without touching a database.

Five minutes. One URL. Your sheet is your backend. Get started free.
