Woocommerce - access meta data values using REST API

Question

I am having a real struggle getting meta data values from woo commerce REST API in a fashion that makes sense and is reliable. I want to access the PayPal returned fraud data for an order so my staff can see the data for security reasons.

I put a request on the REST API to the end point and order id as such: https://[wbeaddress]/wp-json/wc/v3/orders/[order id]

In the meta data returned for the order I can see the following data:

"meta_data": [
    {
        "id": 959,
        "key": "_coupons_hash",
        "value": "****"
    },
    {
        "id": 960,
        "key": "_fees_hash",
        "value": "****"
    },
    {
        "id": 981,
        "key": "_ppcp_paypal_3DS_auth_result",
        "value": {
            "liability_shift": "POSSIBLE",
            "three_d_secure": {
                "enrollment_status": "Y",
                "authentication_status": "Y"
            }
        }
    },
    {
        "id": 978,
        "key": "_ppcp_paypal_fees",
        "value": {
            "gross_amount": {
                "currency_code": "GBP",
                "value": "1379.00"
            },
            "paypal_fee": {
                "currency_code": "GBP",
                "value": "44.29"
            },
            "net_amount": {
                "currency_code": "GBP",
                "value": "1334.71"
            }
        }
    },
    {
        "id": 980,
        "key": "_ppcp_paypal_fraud_result",
        "value": {
            "avs_code": "Y",
            "cvv2_code": "S",
            "address_match": "N",
            "postal_match": "N",
            "cvv_match": "N",
            "card_brand": "VISA",
            "card_last_digits": "1368"
        }
    },

I can access the data using its position in the response for example: by going

$avscode=$results['meta_data'][4]['value']['avs_code'] ?? null;
$cvvmatch=$results['meta_data'][4]['value']['cvv_match'] ?? '';
$card_type=$results['meta_data'][4]['value']['card_brand'] ?? '';
$last_four=$results['meta_data'][4]['value']['card_last_digits'] ?? '';

But I want to be able to use the key name with the accessible values. The array position is not reliable in the checks. How on earth can I access the values for different key names such as this above like avs_code etc. "_ppcp_paypal_fraud_result" and those values such as enrollment_status under the "_ppcp_paypal_3DS_auth_result" key?

Thank you!

Either loop over the array and check if the key of the current item is the one you are interested in; or extract the part you need using àrray_filter`. — C3roe

Would you have an example of this? I am finding it complex as it could be in a first or second layer with an array result in the given layer. — user30379416

$paypalData = array_values(array_filter($results['meta_data'], function($item) { return $item['key'] == '_ppcp_paypal_fraud_result'; })); - array_values after filtering re-indexes the array, so you'll find the desired element (should it exist) at index 0. 3v4l.org/V5pgX — C3roe

@C3roe I like this, really neat! Thank you very much for the example. It's certainly better than the way I Was trying to do it. Thank you! — user30379416

Thanks to @C3roe for coming up with a great way to sort this, per their comment. I wanted to show this answer marked complete.

$paypalData = array_values(array_filter($results['meta_data'], function($item) { return $item['key'] == '_ppcp_paypal_fraud_result'; }));

Excellent way to loop through an array to find specific values.
