When you choose HTTP DCV, Cloudflare automatically adds a verification HTTP token to your domain.

Only use this method if your domain can tolerate a few minutes of downtime.

Note

If you encounter issues with HTTP DCV, refer to the [troubleshooting guide](https://developers.cloudflare.com/ssl/edge-certificates/changing-dcv-method/troubleshooting/).

## Limitations

HTTP DCV is only available for [proxied domains](https://developers.cloudflare.com/dns/proxy-status/). It is possible to manually add the DCV token to the `.well-known/pki-validation/` directory on your origin web server to pre-validate your certificates.

HTTP DCV validation does not work for wildcard certificates. If you want to use wildcard certificates, use [TXT validation](https://developers.cloudflare.com/ssl/edge-certificates/changing-dcv-method/methods/txt/).

Based on your chosen certificate authority (CA), you may also not be able to use HTTP verification with [advanced certificates](https://developers.cloudflare.com/ssl/edge-certificates/advanced-certificate-manager/).

## Setup

### Specify DCV method

If you want to use a [Universal SSL certificate](https://developers.cloudflare.com/ssl/edge-certificates/universal-ssl/enable-universal-ssl/), you will need to edit the `validation_method` [via the API](https://developers.cloudflare.com/api/resources/ssl/subresources/verification/methods/edit/) and specify your chosen validation method.

Alternatively, you could [order an advanced certificate](https://developers.cloudflare.com/ssl/edge-certificates/advanced-certificate-manager/manage-certificates/#create-a-certificate) via the API.

In either case, you would need to set a `"validation_method":"http"` parameter.

### Review other Cloudflare settings

To make sure your domain does not accidentally block HTTP DCV, review your Cloudflare settings for [common setup issues](https://developers.cloudflare.com/ssl/edge-certificates/changing-dcv-method/troubleshooting/).

### Complete DCV

Your HTTP token will be available for the certificate authority as soon as you finish your [partial domain setup](https://developers.cloudflare.com/dns/zone-setups/partial-setup/setup/#3-add-dns-records).

This means that you need to add a CNAME record to Cloudflare in your authoritative DNS and create [proxied DNS records](https://developers.cloudflare.com/dns/proxy-status/) for your hostname within Cloudflare.

This process may involve a few minutes of downtime.

To check whether your certificates have been validated and reissued:

* **Dashboard**: Find the certificate(s) **SSL/TLS** > **Edge Certificates** and make sure that the **Status** is **Active**.
* **API**: Send a [`GET`](https://developers.cloudflare.com/api/resources/ssl/subresources/certificate_packs/methods/list/) request and confirm that your certificate(s) have `"status": "active"`.

## Renewal

Even if you manually handle DCV when issuing certificates in a [partial DNS setup](https://developers.cloudflare.com/dns/zone-setups/partial-setup/), at certificate renewal, Cloudflare will attempt to automatically perform DCV via HTTP.

If all of the following conditions are confirmed at the first attempt, the renewal happens automatically via HTTP.

* Hostnames are proxied.
* Hostnames on the certificate resolve to the IPs assigned to the zone.
* The certificate does not contain wildcards.

Note

To automatically renew certificates that do not meet the referred criteria, consider using [Delegated DCV](https://developers.cloudflare.com/ssl/edge-certificates/changing-dcv-method/methods/delegated-dcv/).
