This is handled natively by Flare now

Though this package will recursively search requests for keys, which may be an improvement depending on the usecase.

Request Data Scrubber for Laravel Flare Reporting

Flare doesn't seem to provide any documentation on scrubbing sensitive data from requests before sending over errors. This package is a simple service provider that allows a config to define what data should be sanitized.

composer require johnwilhite/laravel-flare-scrubber

If you don't already have one, create a config/flare.php file and define a sensitive_data array.

<?php

return [
    'sensitive_data' => [
        'keys' => [
            'ssn',
            'bank_routing_number',
            'credit_card_number'
        ],
        'key_regex' => [
            '/^ssn/'
        ],
        'value_regex' => [
            '/^\d{3}-?\d{2}-?\d{4}$/'
        ]
    ]
];

Before sending your data to flare, this provider will recursively search the request data and sanitize the values of any match. Key matches can apply to entire arrays as well. There are 3 options that can be used optionally and interchangeably:

• keys An exact match to the key name.

• key_regex A regex pattern to match a key.

• value_regex A regex pattern to match a value.

Additionally, you may define the sanitized value text at flare.sensitive_data.sanitization_text. The default is ***SANITIZED***.
