The Problem

Contest operators log hundreds of contacts per hour. Tracking multipliers, verifying callsigns, and managing QSL confirmations is intense.

The Solution

SheetAPI powers your contest station. Log contacts in real-time, auto-calculate scores, flag duplicate contacts, and generate Cabrillo files for submission.

1

Set Up Your Google Sheet

Create a spreadsheet with columns like: Timestamp, Callsign, Band, Mode, RST Sent, RST Rcvd, Exchange, Points

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 ham radio contest logging system data.

Code Examples

Here's how simple it is to work with your ham radio contest logging system 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 ham radio contest logging system records

Create a New Record

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

// Using JavaScript (fetch)
const newRecord = {
  'Timestamp': 'Sample value',
  'Callsign': '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

  method: 'PATCH',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
