As per https://shopify.dev/api/storefront#rate_limits
If you use a server-side library, the IP address of the request will be your server’s address. To ensure your app is throttled correctly, use a delegate access token and pass it in the Shopify-Storefront-Private-Token header from server contexts. Requests using this authentication method can pass the buyer IP into the Shopify-Storefront-Buyer-IP header.
So when I pass Shopify-Storefront-Private-Token and Shopify-Storefront-Buyer-IP I get a 403 Forbidden error. Can anyone help me how to use delegate token to make a call using above method, as we are trying to implement and overcome Storefront API throttling issue as our request happens from one server.
