uri property
Canonical URL directly linking to the product detail page.
It is strongly recommended to provide a valid uri for the product, otherwise the service performance could be significantly degraded. This field must be a UTF-8 encoded string with a length limit of 5,000 characters. Otherwise, an INVALID_ARGUMENT error is returned. Corresponding properties: Google Merchant Center property link. Schema.org property Offer.url.
Implementation
core.String? uri;
