## Add DNS TXT record to verify Webhook URL domain

In order to verify the Webhook URL domain, you need to add Zalo DNS TXT to your domain.

To DNS TXT record to verify the Webhook URL domain, follow these steps:

1. Select Domain Authentication and enter a domain based on the bot region, for example, `cloud.yellow.ai` or `r1.cloud.yellow.ai`.


2. If your domain is not verified, click **Verify now**.


2. Copy the TXT record to establish the [connection between the Webex channel](#connect-zalo-channel-to-your-bo) and your bot on the platform.


3. Once your bot is connected to Zalo, open the following link and keep it active for 10–20 minutes in a browser window:

`https://cloud.yellow.ai/zalo_verifierVzQC6wkaBK1jshzBv_ibOnRbZKpwcbmMDpG.html?bot=<botID>`

To create the above URL, follow these steps:

1. Expand **Upload an HTML file to your website** drop-down and copy the highlighted query parameter.


2. Enter the domain (for example, https://cloud.yellow.ai) that you have specified during the verification and paste the copied query parameter (zalo_verifierVzQC6wkaBK1jshzBv_ibOnRbZKpwcbmMDpG.html).

3. Append your bot ID (`bot=<botID>`) to the URL.

4. Go back to **Domain Authentication**, enter your domain in the input field to verify your domain, and click **Accuracy**.


* Your domain will be successfully verified.
