The Problem

Managing email lists in spreadsheets means manual imports, lost subscribers, and no easy way to segment audiences.

The Solution

SheetAPI converts your subscriber spreadsheet into an API. Capture signups from your website, segment audiences automatically, and sync with your email platform.

1

Set Up Your Google Sheet

Create a spreadsheet with columns like: Email, Name, Status, Source, Subscribed Date, Tags, Opens, Clicks

2

Connect to SheetAPI.pro

Sign up (takes 10 seconds), authorize Google, and paste your sheet URL. Done.

3

Start Using Your API

Get instant REST API endpoints to create, read, update, and delete your newsletter & email list management data.

Code Examples

Here's how simple it is to work with your newsletter & email list management data:

Fetch All Records

# Using cURL
curl -H "Authorization: Bearer YOUR_API_KEY" \
  https://api.sheetapi.pro/v1/YOUR_SHEET_ID

// Using JavaScript (fetch)
const response = await fetch('https://api.sheetapi.pro/v1/YOUR_SHEET_ID', {
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY'
  }
});

const data = await response.json();
console.log(data); // Your newsletter & email list management records

Create a New Record

# Using cURL
curl -X POST \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"Email":"VALUE1","Name":"VALUE2"}' \
  https://api.sheetapi.pro/v1/YOUR_SHEET_ID

// Using JavaScript (fetch)
const newRecord = {
  'Email': 'Sample value',
  'Name': 'Another value'
};

const response = await fetch('https://api.sheetapi.pro/v1/YOUR_SHEET_ID', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify(newRecord)
});

Update a Record

// Update by row ID
const response = await fetch('https://api.sheetapi.pro/v1/YOUR_SHEET_ID/ROW_ID', {
  method: 'PATCH',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
