C# Create Swiss QR-Bill API - Introduction

Introduction

In this document, we will provide a comprehensive guide on creating a Swiss QR-Bill API using C#. The Swiss QR-Bill is a standardized payment slip used in Switzerland for making payments. This API will enable developers to generate QR-Bill codes and integrate them into their applications or systems.

Functionalities

The Swiss QR-Bill API will include the following functionalities:

1. Generate QR-Bill Code

• Generate a QR-Bill code with all the necessary payment information.
• Accept inputs such as recipient's name, address, amount, payment reference, etc.
• Encode the information into a QR-Bill code using the Swiss QR-Bill specification.

2. Validate QR-Bill Code

• Validate the generated QR-Bill code to ensure it meets the Swiss QR-Bill specification.
• Ensure the payment information is correctly encoded and formatted.

3. Save QR-Bill Image

• Generate a high-resolution image of the QR-Bill with the encoded payment information.
• Save the image to a specified path or return it as a binary data stream.
• Allow customization options such as image size, color, logo placement, etc.

4. Generate QR-Bill PDF

• Create a PDF document containing the QR-Bill image along with additional information.
• Include payment instructions, recipient details, amount, due date, etc.
• Support customizable PDF templates with the ability to add company logos, footer text, etc.

Code Snippet

// Code to Generate QR-Bill Code
QRBillGenerator qrBillGenerator = new QRBillGenerator();

// Set payment information
qrBillGenerator.SetRecipient("John Doe");
qrBillGenerator.SetAddress("123 ABC Street, Zurich");
qrBillGenerator.SetAmount(100.50);
qrBillGenerator.SetPaymentReference("INV-12345");

// Generate QR-Bill code
string qrBillCode = qrBillGenerator.GenerateQRBillCode();

// Validate QR-Bill code
bool isValidQRBillCode = qrBillGenerator.ValidateQRBillCode(qrBillCode);

// Save QR-Bill image
string qrBillImagePath = "path/to/save/image.png";
qrBillGenerator.SaveQRBillImage(qrBillCode, qrBillImagePath);

// Generate QR-Bill PDF
string qrBillPdfPath = "path/to/save/pdf.pdf";
qrBillGenerator.GenerateQRBillPDF(qrBillCode, qrBillPdfPath);

Please note that the code snippet above is simplified for demonstration purposes. The actual implementation may require additional error handling, configuration settings, etc.

Conclusion

With the C# Swiss QR-Bill API, developers will be able to easily generate QR-Bill codes, validate them, save images, and generate PDF documents. This will enable seamless integration of Swiss payment slips into various applications and systems.
