Generate Factur-X Invoices with ASP.NET

Learn how to easily integrate GoFX into your ASP.NET stack.

Dealing with complex XML generation in ASP.NET can be extremely tedious. GoFX abstracts all the EN16931 complexity away. Send a simple JSON payload and get a perfectly compliant hybrid PDF back in milliseconds.

Ecosystem Focus

Integrating Factur-X / EN16931 within the ASP.NET ecosystem is now seamless. Avoid building complex XML DOMs manually and let GoFX handle the heavy lifting. Generate hybrid PDF/A-3 invoices directly via our REST API.

Prerequisites

Ensure you have .NET 5+ / HttpClient configured in your environment to make outbound HTTP POST requests to the GoFX API.

> Code Example

using var client = new HttpClient();
var content = new StringContent(jsonPayload, Encoding.UTF8, "application/json");
var response = await client.PostAsync("https://api.gofx.app/v1/invoice/generate", content);
var pdfBytes = await response.Content.ReadAsByteArrayAsync();
await File.WriteAllBytesAsync("facture.pdf", pdfBytes);
