Getting Started

Start posting financial events to GL System in under 5 minutes. No infrastructure to manage — just sign up, get an API key, and integrate.

Quick Start Path​

  1. Create Your Account — Sign up at glsystem.io, choose a plan, and get your API key.
  2. Authentication — Learn how to authenticate API requests using your API key.
  3. Post Your First Event — Create accounts, define posting rules, and post your first financial event.

How It Works​

Base URL​

All API requests use your tenant's base URL:

https://api.glsystem.io/api/v2/

What You'll Need​

  • A GL System account (sign up free)
  • An API key (generated in the portal dashboard)
  • An HTTP client (cURL, Postman, or your application code)

Sample Request​

curl -X POST https://api.glsystem.io/api/v2/gl/events \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "eventKey": "INV-001",
    "eventType": "INVOICE_PAYMENT",
    "amount": "1250.00",
    "currencyCode": "USD"
  }'

GL System automatically applies the matching posting rules, creates balanced journal entries, updates running balances, extends the hash chain, and fires webhook notifications.
