Shipping an app is a major milestone, but it isn’t the end of the development process. In fact, it’s usually when the most useful learning begins.

As soon as a growing number of merchants are using a product across multiple stores, themes and retail models, you get to see a much bigger picture of how it fits into the day-to-day. Brands find new ways to use it, customers interact with it in different ways, and agencies encounter different implementation needs. All of that gives us more info about where to take the product next.

That’s been a big part of how we’ve continued to develop Wysh, our wishlist app for Shopify.

Since launching it in October, we’ve gathered a wealth of insights that have helped us expand and improve the app in a recent update, covering everything from theme compatibility and merchant reporting to integrations and developer tooling.

More flexibility for different ways of selling

One of the clearest things we’ve seen as Wysh has expanded across more Shopify stores is just how much storefront setups can vary.

Different themes handle headers, sections and app blocks in different ways, while agencies often create highly customised storefronts for their clients. We’ve also seen Wysh being used across different retail models, where the role of a wishlist can vary considerably.

For many DTC retailers, moving a saved item into the cart is the obvious next step. For B2B and wholesale merchants, however, a wishlist might form part of a quotation process instead.

Those insights have led us to give merchants and agencies greater control over how Wysh fits into both their storefront and the way they sell. The latest update includes:

• Improved theme support - Wysh now works across Online Store 2.0 sections and legacy theme setups.

• A configurable floating wishlist button - Merchants can add a persistent wishlist trigger without modifying header code.

• A live item counter - Customers can see how many products they’ve saved as they browse.

• Greater Add to Cart control -  Merchants can hide the button globally or for logged-in customers, supporting use cases such as B2B quotations.

Richer insight from wishlist activity

Every time a customer saves a product, they’re giving the merchant an indication of what they’re interested in, even if they’re not ready to buy it yet.

As more customers use Wysh, those interactions create a growing source of intent data that can help merchants understand demand, see how customers are engaging with products, and understand the role wishlists play in generating revenue.

That’s given us an opportunity to make the merchant side of Wysh work even harder, so we’ve now added:

• Improved real-time reporting - The updated dashboard brings together real-time statistics, a live stream of wishlist activity and performance metrics, helping merchants understand what customers are saving and how that activity contributes to revenue.

• AI-assisted analysis with Sidekick - A new app extension lets merchants investigate Wysh data using AI directly within Shopify admin.

• A faster route to useful insights - A new landing page and guided setup wizard help merchants get Wysh up and running quickly, so they can start learning from customer activity sooner.

Wishlists that fit the wider experience

As Wysh has been used across more stores and markets, we’ve learned more about where customers expect to encounter their wishlist and the info they want around it. That’s driven us to make Wysh feel more naturally connected to the wider Shopify experience, while adapting it for different customers and markets, so we’ve added:

• Native customer account integration - Saved wishlists can now sit directly within Shopify’s Customer Account area, alongside order history and other account information.

• Product reviews within wishlists - Merchants can display review stars alongside saved products, including through Judge.me, giving customers useful social proof when they return to items they’re considering.

• 30+ language translations - Wysh now supports over 30 languages across both the customer-facing storefront and merchant dashboard, making it easier for international merchants to offer a localised experience.

Extending the value of customer intent 

A saved product is a useful signal of customer intent, and for merchants using Wysh alongside marketing, loyalty and customer service platforms, we saw an opportunity to make that signal easier to use elsewhere.

Connecting wishlist activity with the wider retail stack opens up a range of practical possibilities - from re-engaging customers when prices drop to rewarding wishlist activity through loyalty programmes or giving customer service teams visibility of high-value intent.

That thinking has led to new ways to connect Wysh with existing workflows:

• Pre-built Shopify Flow templates - Wysh now connects with Klaviyo, Attentive, LoyaltyLion, Slack, Mailchimp and Ometria, without requiring merchants or agencies to build custom webhooks themselves.

• Ready-made workflow triggers - Merchants can use wishlist activity to trigger actions such as price-drop messaging, loyalty rewards and internal notifications.

Greater control for developers

Working with agencies has reinforced something we already know from building for Shopify: there’s a limit to how much flexibility you can provide through settings alone.

Custom storefronts, headless builds and mobile apps all bring different requirements. Trying to anticipate every possible implementation through configuration would restrict what developers can create.

So, rather than adding more settings, we’ve opened up Wysh in two new ways:

• REST API - Core wishlist endpoints allow Wysh data to be queried and updated from external applications, custom backends and mobile apps, supporting bespoke wishlist experiences across headless storefronts and native applications.

• JavaScript SDK - Developers can programmatically add, remove and list saved products, giving them the control to build custom storefront components without relying on Wysh’s standard frontend.

Combined, these updates make Wysh an even more capable and adaptable app. Just as importantly, they reflect how we want to keep developing it - combining our own ideas and experience with what we learn from the people using Wysh across different stores, markets and implementations.

For merchants and agencies, that means an app that continues to develop around the way they work, backed by a team that’s already thinking about what they’ll need next.

The latest version of Wysh is now available on the Shopify App Store.
