Hey @awwa,
You can visit the Visa Developer Error Codes page for cause and resolution.
When dealing with the `ResolveAlias` API and encountering issues like the one you're describing, there are a few steps and checks you can perform to troubleshoot and ensure proper functionality.
Troubleshooting Steps:
1. Check Server Time Synchronization:
Ensure that your test server's system time is synchronized with a reliable time source. Any significant time drift can cause SSL/TLS issues.
2. Review SSL/TLS Configuration:
Since the API uses two-way SSL authentication, ensure that:
- The client certificate is correctly installed on the server.
- The server certificate is correctly installed and trusted on the client side.
- Both certificates are not expired.
3. Verify X-Correlation-Id:
Use the `X-Correlation-Id` (FDTLakVmjU_SC) provided to check Visa’s logs or contact Visa support for more detailed error information.
4. Check Network Configurations:
Ensure there are no network issues or firewalls blocking the requests.
Example Values for API Fields:
Here are example values for the fields you mentioned to help with your tests:
- directoryName:
```json
"directoryName": "VisaDirectory"
```
This field typically refers to a specific directory service that the API interacts with.
- excludedDirectoryName:
```json
"excludedDirectoryName": "MastercardDirectory"
```
This field is used to exclude specific directories from the search or resolution process.
Example Request Body:
Below is an example of a sample JSON request body for the `ResolveAlias` API:
```json
{
"alias": "john.doe@example.com",
"directoryName": "VisaDirectory",
"excludedDirectoryName": "MastercardDirectory"
}
```
Java Example using RestTemplate:
Here’s how you might set up a request in Java:
```java
//
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.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
public class ResolveAliasController {
@PostMapping("/resolveAlias")
public ResponseEntity<String> resolveAlias() {
String apiUrl = "https://sandbox.api.visa.com/resolveAlias";
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.set("X-App-Id", "your-app-id-here");
headers.set("Authorization", "Basic your-base64-encoded-credentials-here");
headers.set("Content-Type", "application/json");
String requestBody = "{ \"alias\": \"john.doe@example.com\", \"directoryName\": \"VisaDirectory\", \"excludedDirectoryName\": \"MastercardDirectory\" }";
HttpEntity<String> entity = new HttpEntity<>(requestBody, headers);
try {
ResponseEntity<String> response = restTemplate.exchange(apiUrl, HttpMethod.POST, entity, String.class);
return response;
} catch (Exception e) {
e.printStackTrace();
return ResponseEntity.status(500).body("Error occurred while calling Visa API");
}
}
}
//
```
By following these steps and using the provided examples, you should be able to troubleshoot the issue more effectively.
Thanks,
Diana
