The Problem

Small libraries use paper cards. Finding books is slow, overdue notices are manual, and popular titles are always checked out.

The Solution

SheetAPI modernizes your library. Patrons search the catalog online, checkouts are tracked automatically, and overdue notices are sent by email.

1

Set Up Your Google Sheet

Create a spreadsheet with columns like: ISBN, Title, Author, Status, Checked Out To, Due Date, Location, Category

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 library catalog & circulation data.

Code Examples

Here's how simple it is to work with your library catalog & circulation 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 library catalog & circulation records

Create a New Record

# Using cURL curl -X POST \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"ISBN":"VALUE1","Title":"VALUE2"}' \ https://api.sheetapi.pro/v1/YOUR_SHEET_ID
// Using JavaScript (fetch) const newRecord = { 'ISBN': 'Sample value', 'Title': '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' }, body: JSON.stringify({ 'Status': 'Updated' }) });
