Requests - Supercycle

Storefront API requests go through the Shopify app proxy, so they’re made to your store’s own domain and Shopify signs them for you. There’s no API key to send. The proxy path is available on the page as window.supercycleAppEmbed.context.proxyPathPrefix. It usually looks like /apps/supercycle. Prepend it to every Storefront API path.

Fetch helper

async function supercycleFetch(method, path, options) {
  if (!path.startsWith("/")) path = `/${path}`;
  const { proxyPathPrefix } = window.supercycleAppEmbed.context;
  const response = await fetch(proxyPathPrefix + path, {
    method,
    headers: { "Content-Type": "application/json" },
    ...options,
  });

  return response.json();
}

window.supercycleAppEmbed is set by the Supercycle Engine app embed, so it’s only present on pages where the app embed is turned on.
