Hey @Aminelmutuk1,
To create an invoice with a QR code for payments using Visa Direct, you will need to follow these steps:
1. Generate a Payment Link or Payment Request: Use Visa Direct API to create a payment request.
2. Generate a QR Code: Use a QR code generator to create a QR code with the payment link.
3. Create an Invoice: Include the QR code in your invoice.
4. Send the Invoice: Send the invoice to your customers.
Step 1: Generate a Payment Link or Payment Request
Visa Direct does not directly provide a payment link generation feature like some other payment gateways. However, you can create a payment request by integrating with Visa Direct's APIs.
You will need to register for Visa Direct and get access to their APIs. The key APIs you will use include:
- Push Funds API: To send money to a card.
- Pull Funds API: To receive money from a card.
Here is a high-level overview of how to use Visa Direct APIs:
```json
POST /visadirect/fundstransfer/v1/pushfundstransactions
Host: sandbox.api.visa.com
Content-Type: application/json
{
"systemsTraceAuditNumber": "451001",
"retrievalReferenceNumber": "330000550000",
"localTransactionDateTime": "2023-10-01T12:00:00",
"acquiringBin": "408999",
"acquirerCountryCode": "840",
"senderPrimaryAccountNumber": "4895142232120006",
"senderCardExpiryDate": "2023-10",
"senderCurrencyCode": "USD",
"amount": "100.00",
"recipientName": "John Doe",
"recipientPrimaryAccountNumber": "4111111111111111",
"transactionCurrencyCode": "USD",
"merchantCategoryCode": "6012",
"sourceOfFundsCode": "03",
"cardAcceptor": {
"name": "Visa Inc. USA-Foster City",
"terminalId": "365539",
"idCode": "VMT200911026070",
"address": {
"state": "CA",
"county": "San Mateo",
"country": "USA",
"zipCode": "94404"
}
}
}
```
Step 2: Generate a QR Code
You can use a QR code generator tool or library to create a QR code with the payment link or payment request details.
Example using Python
```python
# START
import qrcode
# Replace this with your Visa Direct payment link or details
payment_link = "https://your-payment-gateway.com/pay?amount=100¤cy=USD"
# Generate QR code
qr = qrcode.QRCode(
version=1,
error_correction=qrcode.constants.ERROR_CORRECT_L,
box_size=10,
border=4,
)
qr.add_data(payment_link)
qr.make(fit=True)
# Create an image from the QR Code instance
img = qr.make_image(fill_color="black", back_color="white")
# Save the image to a file
img.save("payment_qr_code.png")
# END
```
Step 3: Create an Invoice
Use your preferred invoicing software or a document editor to create an invoice. Insert the QR code image into the invoice.
Example using Google Docs:
1. Open Google Docs and create a new document.
2. Insert the QR code image by going to Insert > Image > Upload from computer.
3. Place the QR code in a prominent position on the invoice.
Step 4: Send the Invoice
Send the invoice to your customers via email or any other preferred method.
Example Invoice Layout
```
-----------------------------------------------------
| Company Name |
| Company Address |
| |
| Invoice Number: 12345 |
| Date: YYYY-MM-DD |
| |
| Bill To: |
| Customer Name |
| Customer Address |
| |
| Description | Quantity | Unit Price | Total |
| ------------------|----------|------------|--------|
| Service/Product | 1 | $100.00 | $100.00|
| |
| Total Amount Due: $100.00 |
| |
| Scan the QR code to make a payment: |
| [QR CODE IMAGE] |
-----------------------------------------------------
```
This will allow your customers to scan the QR code and make the payment.
Thanks,
Diana
