Hey @mansour,
To develop a mobile payment app that allows users to request a virtual card, use it for online transactions, and recharge it for reuse, you can leverage various APIs provided by the Visa Developer Platform. Here are some steps and APIs that you can use to achieve your goal:
1. Virtual Card Creation:
- You can use the Visa Virtual Card API to create virtual cards for your users. This API allows you to generate virtual card numbers that can be used for online transactions.
2. Transaction Processing:
- Use the Visa Direct API to process transactions. This API enables you to send and receive payments, making it suitable for online purchases and other types of transactions.
3. Card Management:
- To manage the virtual cards, such as checking the balance, recharging, or disabling the card, you can use the Visa Card Services API. This API provides functionalities for managing card features and settings.
4. Security and Authentication:
- Ensure secure authentication and authorization using the Visa Token Service API. This API helps in securing the card details and transactions.
Here is a sample code snippet for creating a virtual card using the Visa Virtual Card API:
```python
# START
import requests
url = "https://sandbox.api.visa.com/vpa/v1/virtualcards"
payload = {
"cardType": "VIRTUAL",
"primaryAccountNumber": "4111111111111111",
"expirationDate": "2023-12",
"firstName": "John",
"lastName": "Doe",
"billingAddress": {
"address1": "123 Main Street",
"city": "Somewhere",
"state": "CA",
"postalCode": "90210",
"country": "USA"
},
"email": "john.doe@example.com",
"phoneNumber": "1234567890"
}
headers = {
"Content-Type": "application/json",
"Authorization": "Basic {base64EncodedCredentials}",
"x-api-key": "{your_api_key}"
}
response = requests.post(url, json=payload, headers=headers)
if response.status_code == 201:
print("Virtual card created successfully:", response.json())
else:
print("Error creating virtual card:", response.text)
# END
```
Make sure to replace `{base64EncodedCredentials}` with your Base64 encoded credentials and `{your_api_key}` with your actual API key.
Thanks,
Diana
