This method is in Alpha and may change in the future.
Removes one or more products from a product group.
Removed products are no longer represented in the group's members array, and they no longer appear as siblings on the storefront. The products themselves aren't deleted.
Duplicate IDs in the request are de-duplicated. If any of the requested products aren't currently members of the group, the entire request fails with PRODUCTS_NOT_IN_GROUP and no products are unassigned.
To add products to a group, call Assign Products to Product Group.
This method doesn't return any custom errors, but may return standard errors. Learn more about standard Wix errors.
