Installment checkout

Paste the full cart token from /cart.js (must include ?key=), or paste the entire /cart.js JSON.

Cart token or /cart.js JSON

Load cart & continue

On your storefront (with items in cart), DevTools console:
copy(await (await fetch('/cart.js')).json())
then paste here. A token alone must look like …?key=… — without key Storefront returns null.
