Build a checkout

A short path from an empty cart to a paid order:

From cart to purchase
await subbly.cart.create()
await subbly.cart.addItem({ productId: 3301, quantity: 1 })

await subbly.cart.update({
  customer: { email: 'ada@example.com', tosConsent: true },
  shippingAddress: { /* … */ },
})

const methods = await subbly.cart.getShippingMethods({
  countryId: 826,
  zip: 'NW1 5JD',
})
await subbly.cart.update({ shippingMethodId: methods[0].id })

await subbly.auth.login({ email, password })
await subbly.cart.attachCustomer()

const { invoice } = await subbly.checkout.purchase(subbly.cart.id)

Each step has its own page: cart, items, shipping, authentication and checkout.

Next steps

• Handle errors — what a failed call rejects with.
• Run a funnel — add upsell offers before, during and after checkout.
• Storefront API — the HTTP API the SDK calls.
