In-depth guide
Shopify GraphQL Admin API rate limits — the full failure-mode walkthrough related to shopify.dev, checked against official docs, with linked verified routes.
Steps
Use productCreate to define a product and its options (e.g., Size, Color, Material) — Shopify supports up to 3 options per product
Use productVariantsBulkCreate to bulk-add variants (size/color combinations) to an existing product instead of creating them one at a time
Query the ProductOption and ProductVariant objects to read back option values and variant-level SKU/price/inventory data
Take advantage of the current 2,048-variant-per-product limit (raised from 100 in October 2025) for apparel lines with many size/color combinations
Use productOptionUpdate to add, rename, or reorder option values without recreating the whole product
Known gotchas
The 3-option cap (not the 2,048 variant cap) is usually what blocks apparel catalogs — a 4th option like length or fit requires a third-party options app, not the core API
Bulk variant creation and product creation are separate mutations — a single productCreate call does not also create all variant combinations
Older REST Admin API examples for variants are being superseded by GraphQL; new integrations should build on GraphQL mutations, not the REST product-variant resource
