Admin API call redirection issue

Retired Boards Appdev Metafields

Topic summary

Admin attempts to fetch product details (including metafields) for items in the cart using frontend JavaScript, but encounters 301 (permanent) redirects.

  • Approach: Calls Shopify AJAX API at /cart.js to list cart items, then requests Admin API endpoint /admin/api/2023-01/products/{product_id}.json for each item.
  • Observed issue: Network shows 301 redirects. The author believes the cause is domain mismatch—requests go to the .myshopify.com domain while the store’s primary domain is a custom domain (e.g., furnace.ca), triggering redirection.
  • Technical context: cart.js is part of Shopify’s AJAX API for retrieving cart data. A 301 indicates a permanent redirect to another URL/domain. Admin API is versioned (2023-01) and the code snippet is central to understanding the problem.
  • Status: No solutions or workarounds provided in the thread. The author is seeking guidance on handling domain redirection. Discussion remains open with unanswered questions.

Hi I want to fetch the products that exist in cart for that I am using Js code that checks all the products added in crt page

fetch(‘/cart.js’)
.then(response => response.json())
.then(cart => {
// Loop through each item in the cart
cart.items.forEach(item => {
// Get the product information from Shopify’s AJAX API
fetch(/admin/api/2023-01/products/${item.product_id}.json)
.then(response => response.json())
.then(product => {
// Log the product’s metafields to the console
console.log(product);
});
});
});

I am using this code but this code gives me 301 redirect error.
The reason I found is that cart.js request send to .myshopify.com domain that is now not primary domain . My original domain is for example furnace.ca that’s why it gives me 301 redirect in response in developer network tab .

Can anyone have solution to this issue . Problem is related to domain redirection
Thanks
