# `WardrikHTTP.Input`

Builds an operation's input from a request.

The input merges, in order, so later ones win:

  1. the JSON body
  2. the query string
  3. the path parameters

For webhooks and channels, the input is the raw request instead: `"body"` and `"headers"`.
Bodies over 8 MB are refused.

# `build`

```elixir
@spec build(Plug.Conn.t(), WardrikProtocol.operation(), map()) ::
  {:ok, map(), Plug.Conn.t()} | {:error, Wardrik.Error.t()}
```

Returns the input for `operation` from `conn` and the path `params` it was routed by.
