Prevent redirect to homepage after invalid in Laravel

Also this can be achieved without overriding any function. Laravel is built to support both Json & normal pages.Please change your settings in postman and set Accept to application/json like below

Laravel is SMART ;-)

Your custom FormRequest extends Illuminate\Foundation\Http\FormRequest. Within is a function that performs the redirect called response(). Simply override this function within your custom FormRequest to change how invalid validations are responded to.

namespace App\Http\Requests;use Illuminate\Foundation\Http\FormRequest;use Illuminate\Http\JsonResponse;class CustomFormRequest extends FormRequest{    /**     * Custom Failed Response     *     * Overrides the Illuminate\Foundation\Http\FormRequest     * response function to stop it from auto redirecting     * and applies a API custom response format.     *     * @param array $errors     * @return JsonResponse     */    public function response(array $errors) {        // Put whatever response you want here.        return new JsonResponse([            'status' => '422',            'errors' => $errors,        ], 422);    }}

I faced same problem in Laravel 8. In your request class, you can override failedValidation method.

<?php...use Illuminate\Contracts\Validation\Validator;use Illuminate\Http\Exceptions\HttpResponseException;class RegisterRequest extends FormRequest{    ...    protected function failedValidation(Validator $validator)    {        throw new HttpResponseException(response()->json(['errors' => $validator->errors()], 422));    }    ...}
