To add multiple sites to Cloudflare at once and more efficiently, you can do so via the Cloudflare API.

Adding multiple sites can be useful when you:

* Have multiple domains mapping back to a single, canonical domain (common for domains in different countries - such as `.com.au`, `.co.uk` - that you want protected by Cloudflare).
* Are a [partner](https://www.cloudflare.com/partners/), agency, or IT consultancy, and manage multiple domains on behalf of your customers.
* Are moving an existing set of sites over to Cloudflare.

Using the API will allow you to add multiple sites quickly and efficiently, especially if you are already familiar with [how to change your name-servers](https://developers.cloudflare.com/dns/zone-setups/full-setup/setup/) or [add a DNS record](https://developers.cloudflare.com/dns/manage-dns-records/how-to/create-dns-records/).

This tutorial assumes domains will be added using [full mode](https://developers.cloudflare.com/dns/zone-setups/full-setup/).

***

## Prerequisites

To add multiple sites to Cloudflare via automation, you need:

* An existing [Cloudflare account](https://developers.cloudflare.com/fundamentals/setup/account/create-account/).

* Command line with `curl`

* A Cloudflare [API token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/) with one of the following permissions:

  * Zone-level `Administrator`
  * Zone-level `Zone: Edit` and `DNS: Edit`
  * Account-level `Domain Administrator`

* To have disabled [DNSSEC](https://developers.cloudflare.com/dns/concepts/#dnssec) for each domain at your registrar (where you bought your domain name).
  * Follow this [tutorial](https://developers.cloudflare.com/dns/dnssec/dnssec-active-migration/) to migrate an existing DNS zone without having to disable DNSSEC

Note

If your previous provider allows you to add DNSKEY records on the zone apex and use these records in responses to DNS queries, refer to this [migration tutorial](https://developers.cloudflare.com/dns/dnssec/dnssec-active-migration/) to learn how to migrate a zone with DNSSEC enabled.

***

## Add domains

1. Create a list of domains you want to add, each on a separate line (newline separated), stored in a file such as `domains.txt`.
2. Create a bash script `add-multiple-zones.sh` and add the following. Add `domains.txt` to the same directory or update its path accordingly.

```bash
  for domain in $(cat domains.txt); do
    printf "Adding ${domain}:\n"


    curl https://api.cloudflare.com/client/v4/zones \
    --header "Authorization: Bearer <API_TOKEN>" \
    --header "Content-Type: application/json" \
    --data '{
      "account": {
        "id":"<ACCOUNT_ID>"
      },
      "name": "'"$domain"'",
      "type": "full"
    }'


    printf "\n\n"
  done
```

1. Open the command line and run:

```sh
bash add-multiple-zones.sh
```

Warning

There are limitations on the number of domains you can add at a time. If you attempt to add more than 50 domains at a time, any additional domains will be blocked until your current domains are active.

After adding a domain, it will be in a [`Pending Nameserver Update`](https://developers.cloudflare.com/dns/zone-setups/reference/domain-status/) state.

## Additional options

### jq

[`jq`](https://jqlang.github.io/jq/) is a command-line tool that parses and beautifies JSON outputs.

This tool is a requirement to complete any `Additional options` steps in this tutorial.

```sh
echo '{"foo":{"bar":"foo","testing":"hello"}}' | jq .
```

Refer to `jq` [documentation](https://jqlang.github.io/jq/manual/#basic-filters) for more information.

### Quick scan

Cloudflare offers a [quick scan](https://developers.cloudflare.com/dns/zone-setups/reference/dns-quick-scan/) that helps populate a zone's DNS records. This scan is a best effort attempt based on a predefined list of commonly used record names and types.

This API call requires the domain `ID`. This can be found in the following locations:

* [Create Zone](https://developers.cloudflare.com/api/resources/zones/methods/create/#Request)
* [List Zones](https://developers.cloudflare.com/api/resources/zones/methods/list/)

Using `jq` with the first option above, modify your script `add-multiple-zones.sh` to extract the domain ID and run a subsequent API call to quick scan DNS records.

```js
  for domain in $(cat domains.txt); do
    printf "Adding ${domain}:\n"


    add_output=`curl https://api.cloudflare.com/client/v4/zones \
      --header "Authorization: Bearer <API_TOKEN>" \
      --header "Content-Type: application/json" \
      --data '{
        "account": {
          "id":"<ACCOUNT_ID>"
        },
        "name": "'"$domain"'",
        "type": "full"
      }'`


    echo $add_output | jq .


    domain_id=`echo $add_output | jq -r .result.id`


    printf "\n\n"
    printf "DNS quick scanning ${domain}:\n"


    scan_output=`curl --request POST https://api.cloudflare.com/client/v4/zones/$domain_id/dns_records/scan \
      --header "X-Auth-Email: <EMAIL>" \
      --header "X-Auth-Key: <API_KEY>"`


    echo $scan_output | jq .


  done
```

## Update nameservers

For each domain to become active on Cloudflare, it must be activated in either [Full setup](https://developers.cloudflare.com/dns/zone-setups/full-setup/setup/) or [Partial setup](https://developers.cloudflare.com/dns/zone-setups/partial-setup/setup/). The following script will output a list containing the nameservers associated with each domain.

You can find your zones nameservers in the following locations:

* [Create Zone](https://developers.cloudflare.com/api/resources/zones/methods/create/#Request)
* [Zone Details](https://developers.cloudflare.com/api/resources/zones/methods/get/)

1. Modify your script `add-multiple-zones.sh` to print a CSV with data from the `Create Zone` JSON response.

```js
  for domain in $(cat domains.txt); do
    printf "Adding ${domain}:\n"


    add_output=`curl https://api.cloudflare.com/client/v4/zones \
      --header "Authorization: Bearer <API_TOKEN>" \
      --header "Content-Type: application/json" \
      --data '{
        "account": {
          "id": "<ACCOUNT_ID>"
        },
        "name": "'"$domain"'",
        "type": "full"
      }'`


    # Create csv of nameservers
    echo $add_output | jq -r '[.result.name,.result.id,.result.name_servers[]] | @csv' >> /tmp/domain_nameservers.csv


    domain_id=`echo $add_output | jq -r .result.id`


    printf "\n\n"
    printf "DNS quick scanning ${domain}:\n"


    scan_output=`curl --request POST https://api.cloudflare.com/client/v4/zones/$domain_id/dns_records/scan \
      --header "X-Auth-Email: <EMAIL>" \
      --header "X-Auth-Key: <API_KEY>"`


    echo $scan_output | jq .


  done


  printf "name_servers are saved in /tmp/domain_nameservers"
  cat /tmp/domain_nameservers.csv
```

| ID | ZONE | NAME SERVERS |
| - | - | - |
| \<ZONE\_ID> | `example.com` | `arya.ns.cloudflare.com`, `tim.ns.cloudflare.com` |

1. Use the values in the **NAME SERVERS** column to [update the nameservers](https://developers.cloudflare.com/dns/zone-setups/full-setup/setup/#update-your-registrar) at the registrar of each domain.

***

## Limitations

There are limitations on the number of domains you can add at a time. If you attempt to add more than 50 domains at a time, any additional domains will be blocked until your current domains are active.



After that, you cannot have more pending sites than active sites associated with your Cloudflare account. We recommend waiting until your pending sites have been [activated](https://developers.cloudflare.com/dns/zone-setups/reference/domain-status/) before adding additional domains.

## Common issues

If any errors were returned in this process, the domain may not be registered (or only just registered), be a subdomain, or otherwise been invalid. For more details, refer to [Cannot add domain](https://developers.cloudflare.com/dns/zone-setups/troubleshooting/cannot-add-domain/).
