# Introduction

> Add same-day delivery to your store's checkout with one API call

Rushly is same-day delivery for retail: a customer picks Rushly at checkout, a nearby driver picks up the order from your store, and it's delivered the same day. This is the developer documentation for integrating Rushly directly into your own checkout — if you're a boutique owner without a developer on staff, a no-code option (Shopify app, WooCommerce plugin) is coming soon; reach out at [support@rushly.us](mailto:support@rushly.us) in the meantime.

## How it works

<Steps>
  <Step title="Customer picks Rushly at your checkout">
    Your checkout shows a same-day delivery option alongside your normal
    shipping methods, priced by [delivery tier](/delivery-tiers).
  </Step>

  <Step title="You call POST /orders/create">
    One API call with the customer's info, pickup address (your store), and
    dropoff address. See the [quickstart](/quickstart).
  </Step>

  <Step title="Rushly takes it from there">
    A driver is dispatched automatically, the customer gets a live tracking
    link by SMS, and you're billed per delivery on the card on file for your
    account. See the [order lifecycle](/order-lifecycle).
  </Step>
</Steps>
