Paginate Shopify products with GraphQL cursor-based navigation

Cursor-based pagination is a GraphQL technique that uses pointers (cursors) to track position in a dataset rather than page numbers. It's more efficient than offset pagination for large Shopify product catalogs because cursors are stable even when products are added or removed between queries. This method prevents duplicate or missing items during pagination.

In Shopify's implementation, each product edge in the connection includes a cursor that points to its position. The API returns these cursors along with the product data, allowing you to request the next page by providing the last cursor from the previous response. This creates a reliable chain through your catalog regardless of changes.

GraphQL provides more flexibility than REST when querying Shopify product data. You can request exactly the fields you need in a single query, reducing over-fetching. GraphQL also handles complex relationships better and offers real-time updates through subscriptions. For large catalogs, GraphQL's cursor-based pagination performs better than REST's offset-based pagination.

For example, when updating product prices, a GraphQL query can fetch just the ID, title, and price fields rather than entire product objects. This reduces payload size and speeds up processing. GraphQL's type system also makes it easier to evolve your API without versioning breaks.

• Reduces data transfer by 50-70% compared to REST
• Single request gets all needed data
• Better support for complex nested queries

Cursor pagination makes Shopify automations more reliable when processing large product catalogs. Traditional pagination can skip or duplicate items if products change between requests. Cursor-based navigation maintains consistency even with catalog updates, ensuring complete data synchronization. This is critical for inventory updates, product exports, or batch processing operations.

Consider a nightly product export: with offset pagination, adding new products could shift positions and cause duplicates. Cursor pagination tracks each product's actual position in the catalog, unaffected by additions or removals elsewhere. This reliability is why Shopify recommends cursors for all paginated GraphQL queries.

Common use cases include syncing product catalogs to external systems, batch updating product attributes, generating reports, migrating products between stores, and processing inventory updates. Any scenario requiring reliable access to Shopify's complete product catalog benefits from cursor-based pagination, especially with thousands of products.

For instance, a multi-channel retailer might use this to sync products to a PIM system daily. The cursor approach ensures all products transfer exactly once, even if new items are added during the sync. Another example would be bulk price adjustments during sales events, where consistency is critical.

• Catalog exports for analytics
• Bulk image processing
• Inventory synchronization

n8n handles GraphQL cursor pagination through workflow loops that pass the cursor between requests. The template demonstrates how to extract the cursor from each response and feed it into subsequent queries until all products are processed. This approach maintains state across paginated requests while allowing transformation of each product batch.

The workflow uses n8n's item linking to chain requests together. After each GraphQL query, it checks for a cursor in the response. If found, it generates a new query with that cursor, creating a loop that continues until no more cursors are returned. This pattern can process millions of products with minimal configuration.

Cursor pagination reduces Shopify API load by eliminating redundant data transfers. It processes large catalogs faster than offset pagination since the database can optimize cursor-based queries. Performance gains are most noticeable with catalogs exceeding 1,000 products, where traditional pagination becomes inefficient due to increasing query times per page.

Benchmarks show cursor pagination can be 2-3x faster for catalogs over 10,000 products. The efficiency comes from how databases internally track records - cursors map directly to internal pointers while offsets require counting through records. This difference becomes significant at scale.
