# BuilderX API Controllers
> Conventions for handling HTTP requests and responses at the Web API layer.
## Core
| Topic | Description | Reference |
|-------|-------------|-----------|
| FallbackController | Centralized response handling via tuples | [core-fallback](references/core-fallback.md) |
| Tuple Returns | Standard formats like `{:success, ...}` or `{:failed, ...}` | [core-fallback](references/core-fallback.md) |
## Quick Reference
```elixir
defmodule BuilderxApiWeb.V1.ExampleController do
use BuilderxApiWeb, :controller
def show(conn, %{"id" => id}) do
# Context functions should return tuples compatible with FallbackController instead of standard {:ok, data}
# Example:
{:success, :with_data, %{id: id, name: "Sample"}}
end
def delete(conn, _params) do
# Return success without data
{:success, :success_only}
end
def create(conn, _params) do
# Return failure with a custom reason
{:failed, :with_reason, "Invalid input data"}
# Or return an error from a Changeset validation failure
# {:error, changeset}
end
end
