JSON

What it is

Laravel JSON responses set the content type and encode data.

When to use it

Use deliberate arrays/resources for APIs.

Syntax

response()->json(["data" => $data]);

Example

return response()->json([
    "data" => ["amount_cents" => 1250, "currency" => "USD"],
    "meta" => ["request_id" => $requestId],
]);

Common mistakes

Avoid double-encoding JSON strings; large integers may exceed JavaScript safe integer limits.
