Custom Storefronts FAQ

Welcome to the Custom Storefronts community board. Please read through this information prior to asking your question.

What is a custom storefront?

  • Think mobile apps for your business, a custom front end for your website, adding commerce into a video game, offline commerce such as a smart mirror - and more.
  • If you have questions about customizing your theme please post in the Shopify Design board

Bug Reporting:

  • If you are reporting a bug with a specific SDK please utilize the Github repos. Otherwise, please post it here with the title [bug] followed by a brief description.

Setup Tips:

Rate Limiting:

  • The Storefront API is rated limited by the buyer IP and can not be utilized server-side or with a proxy for this reason
  • The Storefront API utilizes a time-based leaky bucket algorithm and every request to the Storefront API costs at least 0.5 seconds to run

Authentication:

  • The Storefront API is an unauthenticated API and access is managed by scopes
  • For a private app, you will utilize the storefront access token from the Admin. This is different from the API Key and Password used for the Admin API
  • For a public app or Sales Channel, the storefront access token is obtained through OAuth

Checkout:

Cart + Performance: 

  • There is no cart object in the Storefront API
  • It is best practice to only initialize a checkout when necessary
  • A cart UI can be built with localStorage to handle Add To Cart actions for the best performance 

Flash Sales:

  • The Storefront API is not designed to be used for flash sales for two main reasons:
  • Bot protection is unavailable
  • The Storefront API has a limit on the amount of checkouts that can be created per minute. If an API client exceeds this throttle, then a 200 Throttled error response is returned. Shopify recommends designing your app to be resilient to this scenario. For example, you could implement a request queue with an exponential backoff algorithm.
