Update a variant

patch /rest/api/products/{productId}/variants/{variantId}

Updates the Product Variant resource.

Partially updates a variant. The body is a JSON Merge Patch document: any field you include replaces the current value, and any field you omit is left untouched.

Merge Patch semantics

Omit a field to leave it untouched, or send a new value to replace it. Non-nullable fields such as sku and barcode reject null - you can change them but not clear them.
