# How to configure SMS Verification on WHMCS

[![FraudLabs Pro SMS Verification Flow](https://www.fraudlabspro.com/resources/wp-content/uploads/2020/03/sms-flow.png)](https://www.fraudlabspro.com/resources/wp-content/uploads/2020/03/sms-flow.png)

FraudLabs Pro SMS Verification acts as a second fraud protection layer by validating customer's cellphone number right after the fraud validation. This could be useful as it will help you to confirm if the given phone number is valid and owned by the buyer. For example, after the checkout process in WHMCS, the buyer will receive an **SMS (Short Message Service)** that contains the **OTP (One Time Passcode)**for verification. Then, the buyer will need to respond by filling in the correct **OTP**received to successfully authenticate himself/herself. This will certainly lessen your efforts to manually contact them for further verification purpose.

This tutorial will demonstrate how to configure this feature using the [FraudLabs Pro plugin](https://marketplace.whmcs.com/product/630). We assumed that you have installed **FraudLabs Pro plugin** before following this tutorial.

1. In the WHMCS admin page, go to **Setup->Fraud Protection**.
2. Choose **FraudLabs Pro** as the Fraud Module from the dropdown and click on the **Go** button.[![FraudLabs Pro Settings](https://www.fraudlabspro.com/resources/wp-content/uploads/2020/03/screenshot.png)](https://www.fraudlabspro.com/resources/wp-content/uploads/2020/03/screenshot.png)
3. Enable the **FraudLabs Pro Fraud Checking** and **SMS Verification** by checking the checkbox beside it.
4. Enter **FraudLabs Pro API key** in the FraudLabs Pro license key field.
5. In the **SMS Trigger** section, choose an option when the SMS Verification will be triggered. Below are the options provided:

| Payment Method - Bank Deposit | Trigger the SMS Verification if the order is paid by Bank Transfer / Direct Debit |
| Payment Method - PayPal | Trigger the SMS Verification if the order is paid by PayPal |

1. In the **SMS Templates** section, it supports the languages include Afrikaans (af), Arabic (ar), Catalan (ca), Chinese (zh), Croatian (hr), Czech (cs), Danish (da), Dutch (nl), English (en), Finnish (fi), French (fr), German (de), Greek (el), Hebrew (he), Hindi (hi), Hungarian (hu), Indonesian (id), Italian (it), Japanese (ja), Korean (ko), Malay (ms), Norwegian (nb), Polish (pl), Portuguese (pt), Romanian (ro), Russian (ru), Spanish (es), Swedish (sv) and Tagalog (tl).
