To build a schema-first Laravel API, define the request and response shapes your clients can rely on, enforce incoming constraints at the Laravel request boundary, and test that the implementation matches the contract. Form Requests provide Laravel’s native structure for authorization and validation; they do not, by themselves, create or synchronize an OpenAPI or JSON Schema contract.
Decide what the contract covers
A contract describes what a client may send and what the API promises to return. Agree on those shapes before implementation, then make them testable. For a request, define required and optional properties, types, permitted values, nullability, nested structures, and your policy for unexpected fields. Define response shapes and validation-error behavior as well; request validation alone cannot establish the complete API contract.
Keep structural checks distinct from rules that depend on the user, database, or business context. A field can have the right type and still refer to a record the caller may not use, or violate a business invariant. Authorization and application rules remain necessary even when a schema describes the payload.

Enforce the request boundary with a Form Request
Laravel Form Requests put request authorization and validation rules in a custom request class. Laravel documents authorize() as the authorization decision and rules() as the request-data constraints. Keeping them separate makes it clearer whether a request is disallowed because of who is making it or because of what it contains.
#1 Best Overall
<?php
namespace AppHttpRequests;
use IlluminateFoundationHttpFormRequest;
class StoreOrderRequest extends FormRequest
{
public function authorize(): bool
{
// Decide whether this authenticated user may create an order.
return true;
}
public function rules(): array
{
return [
'items' => ['required', 'array'],
'items.*.sku' => ['required', 'string'],
'items.*.quantity' => ['required', 'integer'],
];
}
}The example shows where the checks belong; the actual authorization decision, constraints, and response shape must reflect your API. Do not treat a set of Laravel rules as an OpenAPI or JSON Schema definition unless your application has an explicit, verified integration that maintains that relationship.
Choose a policy for unexpected fields
Decide whether an object may contain keys beyond those in the contract. Laravel’s current documentation describes the FailOnUnknownFields attribute, which rejects incoming fields not defined by the request’s validation rules. Confirm that the Laravel version deployed by your application supports it and follow that version’s documentation for its exact use.
Strict rejection can expose misspelled keys and client/server drift early. Tolerating extra keys can be a deliberate compatibility choice when clients may send fields an older server does not use. Neither policy is universally correct: document the choice and test it so clients can depend on the behavior.
Pass only validated data into application work
After validation, use the Form Request’s validated() method or its safe() interface to obtain the validated subset. Laravel’s validator contract also describes validate() and validated() as returning validated arrays, with validation failures able to raise a ValidationException.
Rank #3
public function store(StoreOrderRequest $request)
{
$input = $request->validated();
return $this->orders->create($input);
}Keep the application layer’s input boundary explicit. Passing the entire request payload onward makes it harder to tell which values were accepted and can undermine a contract that deliberately excludes unrecognized or unvalidated input.
Specify validation errors as client-facing behavior
Laravel’s 13.x validation guide says a failed XHR request returns HTTP 422 with a JSON representation of the validation errors. Treat that as a starting point, not a complete error contract: clients also need a defined envelope and clear rules for identifying which input failed.
- Document the status code and the shape and names of error fields.
- Define how nested fields are identified, including the field-path format.
- Decide whether clients may rely on message text or error ordering; confirm the behavior in your application rather than assuming Laravel guarantees it.
- Test the serialized response from the target application, not just the validator’s internal result.
Test whether implementation and contract agree
Parity is something the project must establish. A shared schema, generated validation code, runtime contract validator, or explicit parity tests are architectural options; the Laravel documentation described here does not establish a built-in OpenAPI-to-Form-Request compiler.

Build tests around the contract’s boundaries, not only a successful example:
- A valid request with the required fields and permitted values.
- Missing required fields, wrong types, and values outside stated constraints.
- Unknown fields, including misspelled keys, under the chosen policy.
- Missing versus explicit
nullvalues wherever the contract distinguishes them. - Nested objects and arrays, including invalid elements at different positions.
- Requests rejected by authorization or application-level rules despite having a structurally valid shape.
- The actual error status, envelope, field paths, and serialization returned to clients.
- Response bodies, to verify that successful behavior also matches the promised contract.
Choose how the contract stays maintained
There is no universally superior implementation from the available Laravel documentation. Choose based on how your team wants to manage drift and compatibility:
| Approach | What the team maintains | Main consideration |
|---|---|---|
| One maintained contract source | A shared definition used to describe the API, with a verified process for enforcing it in Laravel | Confirm that the enforcement integration exists and works with the project’s Laravel version. |
| Contract plus Laravel rules | The contract and Form Request rules as separate artifacts | Use parity tests or review practices to catch divergence between them. |
| Generated validation | A contract and project-specific generation or validation tooling | Verify compatibility, maintenance, and the behavior generated for the constraints your API needs. |
Whichever route you choose, keep authorization and business invariants as explicit application checks, and make unknown-field and error-format behavior part of the tests. A contract is useful only when clients can rely on it and changes to the implementation cannot silently invalidate it.
