Create Product

Creates a new product. Flex automatically determines the product's HSA/FSA eligibility from the supplied name, description, identifiers, and URL; if it can't be resolved synchronously, the product is created with eligibility pending and classification continues in the background, after which a product.updated event may fire. A product.created event is sent to your configured webhook endpoints on success.
