Validate the Certificate Using DNS (Cloudflare)

This section explains how to validate your ACM certificate using DNS through Cloudflare. DNS validation allows ACM to confirm domain ownership automatically.

---

1. Open the certificate request in the ACM console.

2. In the Domains section, locate the CNAME record provided by ACM.

3. Copy the Name and Value fields.

4. Sign in to the Cloudflare dashboard and open the DNS records page for your domain.

5. Add a new DNS record with the following settings:

   • Type: CNAME
   • Name: Paste the Name value from ACM
   • Target: Paste the Value from ACM
   • Proxy status: DNS only (⚠ Cloudflare proxy must be disabled)

6. Save the record.

   Tip

   DNS changes may take several minutes to propagate. ACM will automatically detect the CNAME record once it becomes active.

7. Return to ACM → Certificates and check the certificate status.

8. When the status shows Issued, the certificate is ready to attach to CloudFront.
