Checkout CarrierService API. We found it to be the only solution while building custom rate apps.

Automate & bulk assign products to shipping profile: Auto Shipping Profiles: Shipr
Calculate accurate shipping rates: Shipping Calculator: ShipMagic
Hide, rename, reorder payment methods at checkout: Payment Customization: PayMix
