I have searched and searched, and I cannot find an example of JSON-LD Schema microdata that will cause my Facebook Catalog to recognize all variants of a product that has multiple variants (a t-shirt, for example). So far, I've tried these methods of implementing variants:
- ProductGroup with an array of Products (inside the "hasVariant" ProductGroup property)
- Product with an array of Offers
- An array of Products
With all of these approaches, I've only managed to get Facebook to recognize one single product. Does anybody know how to compose Facebook JSON-LD microdata for a product with multiple variants or where I could find an example of this? Thank you!
