# Set Up Payment SMS Notifications in Klaviyo

Use an SMS flow when you want Klaviyo to send a payment reminder after an **Auction Won** event.

Before you start:

* Connect the [Klaviyo Integration](/integrations/klaviyo.md).
* Complete [Klaviyo's SMS setup](/integrations/set-up-sms-in-klaviyo.md) before building flows.
* Enable [bidder registration](/customers-and-bidders/bidder-registration-and-approval.md) to collect customer phone numbers.

{% hint style="info" %}
To activate bidder registration, visit the **Settings > Auction** page and scroll to the **Registration & Verification** section. Select **Auction Participants > All registered customers** and check the **SMS marketing consent** field under **Registration fields**.
{% endhint %}

**Syncing the Auction Won event to Klaviyo**

For events to appear in Klaviyo, they must first occur in Auction Plus. If no customer has won an auction since you first connected your Klaviyo account, create a test auction, place a bid, then end the listing. This sends the **Auction Won** event to Klaviyo so you can use it in a flow.

> Note: This step can be skipped if an auction listing has already been won since you first connected Klaviyo.

## Create the flow

1. Open **Flows** in Klaviyo.

4. Choose **Auction Plus > Auction Won**.
5. Set the re-entry criteria to **Allow re-entry after a time period** for at least 1 hour. This helps avoid sending too many SMS messages when a customer wins multiple items at once.\
