Hey there, I have been trying to checkout my Product (having a recurring subscription) with web checkout flow on iOS and found out that to support the product with the subscription you have to implement Native APIs
So, I started looking into fetching the products with their subscription plan
Now, the problem is I have been trying to hit the storefront API where I can see the product (recurring subscription) with this link:
But API is throwing the Access Denied Error even after having the expected permission
I am getting the below error:
“data”: {
“product”: null
},
“errors”: [
{
“message”: “Access denied for sellingPlanGroup field. Required access: unauthenticated_read_selling_plans access scope.”,
“locations”: [
{
“line”: 4,
“column”: 5
}
],
“path”: [
“product”,
“sellingPlanGroups”
],
“extensions”: {
“code”: “ACCESS_DENIED”,
“documentation”: “https://shopify.dev/api/usage/access-scopes”,
“required access”: “unauthenticated_read_selling_plans access scope.”
}
}
]
}
I have given the permission “unauthenticated_read_selling_plans” for storefront Access Token, but I am still getting the same error
Using the below URL and Graphql Query for my store to fetch the products 
https://lh-demo-store.myshopify.com/api/2021-10/graphql.json
{
product(handle:“iPhone”) {
requiresSellingPlan
sellingPlanGroups(first:1) {
edges {
node {
name
options {
name
values
}
sellingPlans(first: 3) {
edges {
node {
id
name
description
recurring deliveries
options {
name
value
}
}
}
}
}
}
}
}
}
Please help me with the solution.
