## 🧑‍💻 SDK Usage

❗❗❗[Read more about our Medusa compatible SDK here](https://github.com/alphabite-dev/medusa-client/tree/main)

```ts
import { AlphabiteMedusaClient, wishlistPlugin } from '@alphabite/sdk'

const sdk = new AlphabiteMedusaClient({
  {
    baseUrl,
    debug: process.env.NODE_ENV === "development",
    publishableKey: process.env.NEXT_PUBLIC_MEDUSA_PUBLISHABLE_KEY,
  },
  [wishlistPlugin],
  {
    getAuthHeader: () => { return { authorization: `Bearer ${customerJwt}` } },
  }
})

// Create wishlist
await sdk.alphabite.wishlist.create({ name: 'My Sneakers' })

// Add item
await sdk.alphabite.wishlist.addItem({
  id: 'wishlist_id',
  product_variant_id: 'variant_id',
})

// List items
const { data } = await sdk.alphabite.wishlist.listItems({ id: 'wishlist_id' })
```

## 🧪 Guest Wishlist Flow

Guest wishlists work like guest carts:

1. Create a wishlist (no auth required)
2. Save the `id` in a cookie
3. Use that ID for listing/adding/removing items
4. When the user signs up or logs in, call the `transfer` endpoint to associate it:

```ts
await medusa.alphabite.wishlist.transfer({ id: wishlistId })
```

After that, the cookie is no longer needed.

---

## 🧩 Requirements

- Medusa v2.5.0+
- Works with both `@medusajs/types` and `@medusajs/framework`

---

## 📭 Postman Collection

You’ll find the ready-to-import Postman collection at:

```
docs/postman/WishlistPlugin.postman_collection.json
```

Use it to explore and test all endpoints interactively.
