Calculate Cart Taxes

Add Shipping Method to Cart POST

Add a shipping method to a cart. Use this API route when the customer chooses their preferred shipping option. If the chosen shipping option's `price_type` is `calculated`, its price is computed by the associated fulfillment provider when it's added to the cart. If the provider fails to calculate the price, this route returns an error.

List Collections GET

Retrieve a list of collections. The collections can be filtered by fields such as `handle`. The collections can also be sorted or paginated.
