⚡Quickstart

Once your preparation is complete, sending data is nearly instantaneous. This guide focuses on achieving your first successful API call.

0. Prerequisite: The Store ID

Before sending a transaction, ensure you have the storeId generated during the Outlet Mapping phase. Transactions sent with an unknown store identifier will return a 404 Not Found error.

1. Authentication

To authenticate, add an Authorization header with your API Key .

• Base URL: https://api.fyre.app/v1

• Header: Authorization: Bearer <YOUR_API_KEY>

2. Send a Transaction

Fyre.app uses the JSON format for its readability and parsing efficiency . Use this minimal example to ingest a sale:

curl \-X POST https://api.fyre.app/v1/ingest \\  
  \-H "Authorization: Bearer $FYRE\_API\_KEY" \\  
  \-H "Content-Type: application/json" \\  
  \-d '{  
    "transactionId": "TRX-123456",  
    "storeId": "SHOP-LONDON-01",  
    "amount": 12.50,  
    "currency": "GBP",  
    "timestamp": "2026-02-12T16:00:00Z",  
    "items":  
  }'
