Is there a way to buy items from a vendor?

Is there an easy way to buy certain items from a vendor? Tried looking through the api but don't see anything. I see there is something to sell items to a vendor from your inventory but nothing for buying or am I missing it?

<Lua Code="BuyItemFromVendor(12345, 1)" />

Use that after you interact with a Vendor.
