hey @supriya7768,

To test the New Card API in the sandbox environment and obtain the X-App-Id value, follow these steps based on the Visa Developer Platform documentation:

1. Obtain X-App-Id:
- Log in to your Visa Developer account.
- Navigate to your project dashboard.
- Select the project you are working on.
- In the project details, you will find the API key and other credentials. The X-App-Id is usually listed under the project credentials or settings. It is a unique identifier for your application.

2. Sandbox Testing with Postman:
- Ensure you have the Postman application installed and set up.
- Create a new request in Postman.
- Set the request type (GET, POST, etc.) as required by the New Card API.
- Enter the sandbox URL for the New Card API endpoint.
```
Example URL: https://sandbox.api.visa.com/newcard/endpoint
```
- In the Headers section of your request, add the following headers:
```
X-App-Id: <Your X-App-Id>
Authorization: Basic <Your Base64 Encoded Credentials>
Content-Type: application/json
```
- To obtain the Base64 Encoded Credentials, encode your API key and secret in the format apikey:secret and then Base64 encode this string.
- In the Body section, provide the necessary JSON payload as required by the New Card API.
```json
{
"exampleField1": "value1",
"exampleField2": "value2"
}
```
- Send the request and analyze the response.

3. Troubleshooting:
- Ensure that your API key and secret are correct and have the necessary permissions for the New Card API.
- Verify that your sandbox environment is correctly set up and that you are using the correct endpoint URL.
- Check the API documentation for any specific requirements or additional headers that may be needed.
