Create a spreadsheet with columns like: Date, Client, Project, Task, Hours, Rate, Amount, Billable, Invoiced

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 consultant timesheet & billing data.

Code Examples

Here's how simple it is to work with your consultant timesheet & billing data:

Fetch All Records

// 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 consultant timesheet & billing records

Create a New Record

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