Back-in-stock alerts on WhatsApp for Shopify

When a variant is sold out, the product button lets the shopper ask for an alert on WhatsApp. WhatsApp Pilot records the request for that exact variant and, when Shopify shows it available again, sends the shopper a WhatsApp message automatically.

The customer journey

The shopper selects a sold-out variant.
They tap Notify me when back in stock.
WhatsApp opens with a prepared message and a unique request reference.
The shopper sends the message. Sending it is what creates the request.
WhatsApp Pilot registers the request for that specific product variant.
Shopify stock availability is monitored.
When the variant is available again, the shopper receives a WhatsApp notification.

Why it is easy for shoppers

No Shopify customer account is required.
No email capture form.
The request is linked to the WhatsApp number that sent it, so there is nothing to type.
The alert arrives in the same chat, with the link to buy.

Accurate by design

Requests are stored per variant, so a shopper waiting for Black / Large is not alerted about White / Small.
A repeated request for the same variant from the same number is not counted twice.
Availability is confirmed against Shopify before an alert is sent.
Each alert is recorded once the request has been notified.

Restock messages in your languages

You write the restock message for each language your store uses, with the product name, variant name and product link filled in automatically. Defaults in English, Arabic, French, Portuguese and Spanish are included, and the shopper is notified in the language of the storefront they requested from.

Frequently asked questions

Can Shopify send back-in-stock alerts through WhatsApp?

Yes, with WhatsApp Pilot Pro. Shoppers request an alert from the product button, and the app sends a WhatsApp message when the variant is available again.

Do customers need a Shopify account to request stock alerts?

No. There is no account and no email form. The request is tied to the WhatsApp number the shopper sends it from.

How are product availability requests recorded?

When the shopper sends the prepared WhatsApp message, the app reads its request reference and saves the request against that product variant. Tapping the button alone does not create a request; the message has to be sent.

What happens if the same shopper asks twice?

A repeat request for the same variant from the same number is recognised and counted once.

Is this included in the Free plan?

No. Back-in-stock requests and automatic restock notifications are Pro features.

Which languages can the restock message use?

Any language your store sells in. Each language has its own editable template, with defaults in English, Arabic, French, Portuguese and Spanish.
