Turn every purchase into lasting loyalty.

The ClosetPort API transforms your confirmation page into a styling relationship. Shoppers save their purchase to a living wardrobe, and you become the brand they return to—not because of an email, but because you're woven into their daily ritual.

Why leading retailers choose ClosetPort

We don't treat checkout as the end. It's the beginning of a customer's relationship with what they just bought—and with you.

Retention that compounds

Shoppers who catalog items in ClosetPort receive curated outfit moments featuring your pieces. Every styling prompt is a reason to return, browse, and complete their look with you.

Confidence at purchase

As soon as they buy, customers see how new pieces integrate with their existing wardrobe. The result: fewer returns, higher satisfaction, and garments that actually get worn.

The post-purchase advantage

Most brands lose momentum after the order ships. ClosetPort keeps you present—a trusted stylist in their pocket, quietly reinforcing “this is where I shop.”

Inside the API

Embedded seamlessly in your checkout experience, ClosetPort offers one elegant invitation: “Add this to your wardrobe?”

Frictionless opt-in

We capture order details through your secure checkout flow. One tap, and their purchase joins their digital closet.

Intelligent styling

Line items, images, and metadata flow to our edge infrastructure. Within hours, customers receive outfit suggestions that feature what they just bought—styled with pieces they already own and complementary items from your catalog.

Brand continuity

Every interaction feels native to your aesthetic. Customize messaging, co-brand styling prompts, and ensure your voice carries through every touchpoint.
