X-App-Id (VisaNet Connect - Card Services)

[thai-ru]

I'm testing out the New Card API https://sandbox.api.visa.com/connect/v1/cardServices/new  endpoint but i need to pass the X-App-Id

Anyone with an idea on how to get it?

Hey @thai-ru,

To use the New Card API from Visa's sandbox, you need the `X-App-Id` for authentication. Here's how to get it:

1. Register on Visa Developer Portal:
Create an account on the [Visa Developer Portal](https://developer.visa.com/).

2. Create a New Project:
- Log in and click "Create a New Project".
- Select the New Card API.

3. Get Your Credentials:
- After creating the project, you'll receive credentials including the `X-App-Id`.
- Find the `X-App-Id` under the "Credentials" tab along with the `API Key` and `Shared Secret`.

4. Set Up Authentication:
- You may need mutual SSL authentication. Follow the guide on the Visa Developer Portal to download the certificate and configure your HTTP client.

Here's a Java example using Spring Boot and RestTemplate:

```java
// START GENAI@CHATGPT4
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
public class VisaCardServiceController {

@GetMapping("/newCard")
public ResponseEntity<String> getNewCard() {
String apiUrl = "https://sandbox.api.visa.com/connect/v1/cardServices/new";
RestTemplate restTemplate = new RestTemplate();

HttpHeaders headers = new HttpHeaders();
headers.set("X-App-Id", "your-app-id-here"); // Replace with your actual X-App-Id
headers.set("Authorization", "Basic your-base64-encoded-credentials-here"); // Replace with your actual authorization header

HttpEntity<String> entity = new HttpEntity<>(headers);

try {
ResponseEntity<String> response = restTemplate.exchange(apiUrl, HttpMethod.GET, entity, String.class);
return response;
} catch (Exception e) {
e.printStackTrace();
return ResponseEntity.status(500).body("Error occurred while calling Visa API");
}
}
}
// END GENAI@CHATGPT4
```

Replace `"your-app-id-here"` and `"your-base64-encoded-credentials-here"` with your actual credentials. Consult Visa Developer documentation for additional setup steps and details.
