Extract Invoice with PHP Integration — OCR for Laravel & Symfony

Logistics companies process thousands of Invoice documents monthly. Using Php to automate Invoice data extraction eliminates manual entry, reduces errors, and speeds up document processing from minutes to seconds. With the Cargoffer OCR API, you can integrate Invoice extraction into any Php application in under 10 lines of code.

First, get your free API key from the dashboard. Then install the HTTP client for Php and configure authentication. The API uses Bearer token auth — pass your key in the Authorization header.

Use the POST /api/upload endpoint to send the document file. The system auto-detects Invoice format and routes it to the best extraction model. Upload in PDF, image, or Excel format.

provider_name, provider_nif, invoice_number, issue_date, due_date, line_items, totals, iban, payment_method.

The complete Php integration code handles file upload, extraction request, polling for results, and error management. Error types: 401 (invalid key), 402 (quota exceeded — upgrade your plan), 429 (rate limit — wait and retry), 422 (malformed request).

Each Invoice extraction costs from 0.002 EUR per page. The free plan includes 1 page. The Pro plan (49 EUR/month) covers 1,000 pages — enough for 500000 Invoice documents. Manual Invoice data entry costs 3-15 EUR per document — OCR saves 99%.
