Sold out? Bring them back on WhatsApp.

Wapsi sits on your sold-out product pages and collects WhatsApp signups. The moment you restock, we WhatsApp everyone who was waiting.

How it works

Three steps. No code. About five minutes.

Connect your WhatsApp Business account, pick the template you want shoppers to receive, and turn the storefront widget on. Done.

01

Add to Shopify.

One-click install from the Shopify App Store. We bill through Shopify — same monthly invoice as your store, in your store's currency.

02

Connect WhatsApp.

Paste your Zoko credentials. We test the connection and pull your approved WhatsApp templates automatically.

03

Flip the switch.

Enable the widget in one click — your sold-out product pages start collecting WhatsApp signups.

Matches your store

A widget that looks like you built it.

Most "notify me" buttons look bolted on. Wapsi's doesn't. Click Match my theme and we read your store's colors, corners, and font straight from your live theme, then style the widget to match — in one click. Preview it live, and fine-tune any color by hand if you want the final say.
