# Custom Unique Links for Gamezop

{% hint style="warning" %}
**Do not open your Gamezop Unique Link within an iframe.** Gamezop Game Centre does not work within iframes.
{% endhint %}

To get your own Custom Gamezop Unique Link, follow these steps:

#### Step 1: Identify a sub-domain for the Gamezop Game Centre

For this document, we will assume you own `footballnews.com` and you want our Game Centre on `games.footballnews.com`

{% hint style="info" %}
The sub-domain should be of a root domain which is already approved for Google AdSense.
{% endhint %}

#### **Step 2: Get your Gamezop Unique Link**

Follow the steps mentioned [here](/publishers/gamezop/types-of-integration/integrate-unique-link.md) to get your regular Gamezop Unique Link.

#### **Step 3: Contact your IT team to make CNAME records**

**Step 3.1: Domain set up:** Ask your IT team to set up a CNAME record on your domain. You will need to CNAME your subdomain from Step 1 to your Gamezop Unique Link from Step 2. 

Let's assume your Gamezop Unique Link is `3025.play.gamezop.com`

In that case, you will set a CNAME record for `games.footballnews.com` with the alias as `3025.play.gamezop.com`

**Step 3.2: SSL validation:** In order to be able to run our Game Centre on your domain, we need to have an SSL certificate linked to your subdomain from Step 1. This allows us to run everything on the recommended `https` protocol.

To generate this certificate, we need to add another CNAME record, which your Gamezop Account Manager will provide to you. It is your responsibility to ensure this DNS record is not removed at any point of time, or users may start to see safety warnings from browsers when they visit your games subdomain.

#### **Step 4: Get your domain verified on Gamezop's Google Ad accounts**

Add this line at the end of your `ads.txt` file:

```
google.com, pub-3452022011371122, DIRECT, f08c47fec0942fa0
google.com, pub-8414854470825940, DIRECT, f08c47fec0942fa0
google.com, pub-7766717304456825, DIRECT, f08c47fec0942fa0
google.com, pub-2506150943914125, DIRECT, f08c47fec0942fa0
google.com, pub-6968738577620513, DIRECT, f08c47fec0942fa0
google.com, pub-4727832945977825, DIRECT, f08c47fec0942fa0
google.com, pub-6598661725544892, DIRECT, f08c47fec0942fa0
```

Your `ads.txt` file must be hosted on your root-domain. For example, in this case above, it would have to be on `footballnews.com/ads.txt` . Learn more about ads.txt [here](https://support.google.com/adsense/answer/12171612?hl=en).

This is needed for us to get your domain added to our Google AdSense / AdExchange accounts, so that we can start delivering ads.

#### Step 5: Make `ads.txt` entry

In the `ads.txt` file hosted on your root domain, add an entry to reference your games subdomain. In the above example, you would add the following line to the end of your `footballnews.com/ads.txt` file:

```
subdomain=games.footballnews.com
```

What this does is that it instructs ad networks to look also look within the [`ads.txt` file of that subdomain](#user-content-fn-1)[^1]. Since the sub-domain is managed by us, it will always have our latest `ads.txt` entries.

[^1]: In this case, `games.footballnews.com/ads.txt`
