The Problem

Sales teams send proposals into the void. Follow-ups are forgotten, conversion data is missing, and you can't improve what you don't measure.

The Solution

SheetAPI tracks every proposal. Automated follow-ups keep deals alive, conversion rates reveal what works, and pipeline forecasting becomes data-driven.

1

Set Up Your Google Sheet

Create a spreadsheet with columns like: Proposal #, Client, Value, Sent Date, Status, Follow-up Date, Win/Loss, Close Date

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 sales proposal management data.

Code Examples

Here's how simple it is to work with your sales proposal 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 sales proposal management records

Create a New Record

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