Collection retrival issue using api endpoint

https://{shop_name}.myshopify.com/admin/api/{version}/collections.json

this is my endpoint. When I try to access this endpoint using Postman the response is like this:

{
“errors”: “Not Found”
}

how I can retrieve Collections

Hi there!

Receiving a “Not Found” error can be a little confusing when you’re trying to access the Collections endpoint. There are a couple of common reasons why this might happen:

  1. The shop_name or version specified in the URL might not be correct. Make sure you replace {shop_name} with your actual shop name (without .myshopify.com) and {version} with the current API version you are using (for example, ‘2023-10’).

  2. It’s also possible that you may not have the necessary permissions to access the store, or the store might no longer be active.

If you’ve checked these and the issue persists, it could be beneficial to review the API documentation once more, or consider reaching out to Shopify support for further assistance.

Hope this helps you get back on track!
