Saleor API Investigation

When to Use

Use this skill when:

• •Saleor API behavior is unclear from documentation
• •You're getting unexpected permission errors
• •You need to understand the exact data model
• •Documentation doesn't answer your question

Instructions

1. Check Documentation First

• •Saleor API Reference - GraphQL schema
• •Saleor Developer Docs - Guides and concepts

2. Clone Saleor Core (Source of Truth)

When docs aren't enough, check the source:

cd /tmp && git clone --depth 1 https://github.com/saleor/saleor.git saleor-core

3. Key Directories

For detailed directory structure and grep patterns, see KEY_DIRECTORIES.md.

Examples

Example: Does product.attributes filter by visibleInStorefront?

Investigation in saleor/graphql/product/resolvers.py:

def resolve_product_attributes(root, info, *, limit):
    if requestor_has_access_to_all_attributes(info.context):
        dataloader = AttributesByProductIdAndLimitLoader        # Admin: ALL
    else:
        dataloader = AttributesVisibleToCustomerByProductIdAndLimitLoader  # Customer: FILTERED

Conclusion: Yes, storefront users only see visibleInStorefront=True attributes. No client-side filtering needed.

Example: Token-Based Data Filtering

Saleor filters data based on authentication:

This applies to many "visible in storefront" flags across Saleor.

Key Insights

Storefront Auto-Filtering

When building storefront features, you typically don't need to:

• •Fetch visibleInStorefront field
• •Filter data client-side

The API already returns only what's meant to be shown based on your token.

Product Types Control Variant Attributes

Which attributes appear on variants is configured at the ProductType level:

Dashboard → Configuration → Product Types → [Type] → Variant Attributes

If an attribute doesn't appear in variant.attributes, check the ProductType configuration.

Anti-patterns

❌ Don't guess API behavior - Check the source
❌ Don't filter visibleInStorefront client-side - API does it
❌ Don't assume attribute presence - Check ProductType config
