# Listing certificate tags
ListTagsForCertificate

The following example shows how to use the [ListTagsForCertificate](https://docs.amazonaws.cn/acm/latest/APIReference/API_ListTagsForCertificate.html) function.

```
package com.amazonaws.samples;

import com.amazonaws.services.certificatemanager.AWSCertificateManagerClientBuilder;
import com.amazonaws.services.certificatemanager.AWSCertificateManager;
import com.amazonaws.services.certificatemanager.model.ListTagsForCertificateRequest;
import com.amazonaws.services.certificatemanager.model.ListTagsForCertificateResult;

import com.amazonaws.services.certificatemanager.model.InvalidArnException;
import com.amazonaws.services.certificatemanager.model.ResourceNotFoundException;
import com.amazonaws.AmazonClientException;

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.regions.Regions;


/**
 * This sample demonstrates how to use the ListTagsForCertificate function in the Amazon Certificate
 * Manager service.
 *
 * Input parameter:
 *   CertificateArn - The ARN of the certificate whose tags you want to list.
 *
*/

public class AWSCertificateManagerExample {

   public static void main(String[] args) throws Exception{

      // Retrieve your credentials from the C:\Users\name\.aws\credentials file in Windows
      // or the ~/.aws/credentials file in Linux.
      AWSCredentials credentials = null;
      try {
          credentials = new ProfileCredentialsProvider().getCredentials();
      }
      catch (Exception ex) {
          throw new AmazonClientException("Cannot load your credentials from file.", ex);
      }

      // Create a client.
      AWSCertificateManager client = AWSCertificateManagerClientBuilder.standard()
              .withRegion(Regions.US_EAST_1)
              .withCredentials(new AWSStaticCredentialsProvider(credentials))
              .build();

      // Create a request object and specify the ARN of the certificate.
      ListTagsForCertificateRequest req = new ListTagsForCertificateRequest();
      req.setCertificateArn("arn:aws:acm:region:account:certificate/12345678-1234-1234-1234-123456789012");

      // Create a result object.
      ListTagsForCertificateResult result = null;
      try {
         result = client.listTagsForCertificate(req);
      }
      catch(InvalidArnException ex) {
         throw ex;
      }
      catch(ResourceNotFoundException ex) {
         throw ex;
      }

      // Display the result.
      System.out.println(result);

   }
}
```

The preceding sample creates output similar to the following.

```
{Tags: [{Key: Purpose,Value: Test}, {Key: Short_Name,Value: My_Cert}]}
```
