What is the BigCommerce + Sizebay integration

If you sell apparel or footwear on BigCommerce, size questions quietly tax your business every day. Shoppers hesitate on the PDP, support gets the same “what size should I get?” tickets, and returns pile up when fit expectations miss. The BigCommerce Sizebay integration connects your catalog and product-level sizing data with Sizebay’s size recommendation and virtual try-on experience, so fit guidance appears where it matters – on product pages and in the buying flow. It turns sizing from a guess into a consistent, measurable part of your merchandising and CX. This setup fits you if fit-related hesitation and returns are meaningful at your current order volume and SKU count.

How the BigCommerce Sizebay integration works technically

• Product identifiers (SKU, product ID, variant attributes) are mapped between BigCommerce and Sizebay to keep recommendations aligned to the correct PDP and variant.

• Size charts and size rules are associated to products, categories, or attributes, with option values (EU/US/UK sizes, width, inseam, and fit notes) mapped to Sizebay’s sizing model.

• Catalog syncs transfer new and updated products, variants, and option changes; delta updates send only changed records to reduce reprocessing.

• A storefront widget renders on BigCommerce PDP templates and calls Sizebay services at runtime to return size guidance and virtual try-on outputs based on shopper inputs.

• Event payloads (views, interactions, and recommendation outcomes) are captured and attributed to product and variant context for reporting and model tuning.

• Sync errors and schema mismatches are logged with record-level details, and retries handle transient API failures to keep catalog and sizing data consistent.
