Set Up Payment SMS Notifications in Klaviyo

Build an automated Klaviyo SMS flow that sends payment reminders from the Auction Won event.

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.

• Complete Klaviyo's SMS setup before building flows.

• Enable bidder registration to collect customer phone numbers.

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.

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.
