Resending validation email - AWS Certificate Manager
Services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the AWS European Sovereign Cloud Region, see the AWS European Sovereign Cloud User Guide.

Resending validation email

Important

Throughout 2027, AWS Certificate Manager will deprecate email validation for new public certificates and renewals. Use DNS validation instead. For more information, see AWS Certificate Manager will discontinue email validation to prove domain validation for certificates on the AWS Security Blog.

The following example shows you how to use the ResendValidationEmail function. 

package com.amazonaws.samples;

import com.amazonaws.services.certificatemanager.AWSCertificateManagerClientBuilder;
import com.amazonaws.services.certificatemanager.AWSCertificateManager;
import com.amazonaws.services.certificatemanager.model.ResendValidationEmailRequest;
import com.amazonaws.services.certificatemanager.model.ResendValidationEmailResult;

import com.amazonaws.services.certificatemanager.model.InvalidDomainValidationOptionsException;
import com.amazonaws.services.certificatemanager.model.ResourceNotFoundException;
import com.amazonaws.services.certificatemanager.model.InvalidStateException;

/**
 * This sample demonstrates how to use the ResendValidationEmail function in the AWS Certificate

 * Input parameters:

 *   Domain - FQDN in the certificate request.
 *   ValidationDomain - The base validation domain that is used to send email.

public class AWSCertificateManagerExample {

   public static void main(String[] args) {

      // 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 set the input parameters.
      ResendValidationEmailRequest req = new ResendValidationEmailRequest();
      req.setCertificateArn("arn:aws:acm:region:account:certificate/12345678-1234-1234-1234-123456789012");
      req.setDomain("gregpe.io");
      req.setValidationDomain("gregpe.io");

      // Create a result object.
      ResendValidationEmailResult result = null;
      try {
         result = client.resendValidationEmail(req);
      }
      catch(ResourceNotFoundException ex)
      {
         throw ex;
      }
      catch (InvalidStateException ex)
      {
         throw ex;
      }
      catch (InvalidArnException ex)
      {
         throw ex;
      }
      catch (InvalidDomainValidationOptionsException ex)
      {
         throw ex;
      }

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

   }
}

The preceding sample resends your validation email and displays an empty set.
