FormX Invoice OCR API
What FormX Invoice OCR API is
FormX Invoice OCR API extracts invoice details and returns structured data for use in finance, accounting, and ERP systems. The REST API can identify vendor details, invoice number and dates, line items, subtotal, tax, grand total, currency, and payment terms. FormX says it uses OCR, machine learning, and large language models to locate fields. It supports invoices with varied layouts without templates, including ZUGFeRD and Factur-X files, from both visible PDF content and embedded XML.
Results can be delivered as JSON, Excel, or CSV, or passed into other systems through API responses, webhooks, or batch processing. Named integration options include SAP S/4HANA, SAP Business One, Oracle NetSuite, QuickBooks Online and Desktop, and Microsoft Dynamics 365. SDKs are available for Python, Node.js, Java, and .NET. Customers can customize or train extractors for selected fields, with training possible from one sample image. FormX says API uploads are held in memory and disposed of after extraction, encrypted using HTTPS, and excluded from AI model optimization unless requested. Selectable processing regions are the United States, Taiwan, and Singapore.
