amazon sp api update verification status of order

I am using sp api for php written by jlevers. Here is the link: https://github.com/jlevers/selling-partner-api/blob/main/docs/Api/OrdersV0Api.md#updateVerificationStatus

---

I want to update verification status of order. Here is the code:

$apiInstance = new \SellingPartnerApi\Api\OrdersV0Api($config);

$data1 = [ 'status'=>\SellingPartnerApi\Model\OrdersV0\VerificationStatus::APPROVED, // 'external_reviewer_id' => "reviewer1234", // How can I get this external_reviewer_id ? ]; $requestBody = new \SellingPartnerApi\Model\OrdersV0\UpdateVerificationStatusRequestBody($data1);

$data2 = [ 'regulated_order_verification_status'=>$requestBody, ]; $payload = new \SellingPartnerApi\Model\OrdersV0\UpdateVerificationStatusRequest($data2);

try { $result = $apiInstance->updateVerificationStatus($order_id, $payload); } catch (Exception $e) { echo 'Exception when calling OrdersV0Api->updateVerificationStatus: ', $e->getMessage(), PHP_EOL; }

---

This is the $payload object.

SellingPartnerApi\Model\OrdersV0\UpdateVerificationStatusRequest Object ( [container:protected] => Array ( [regulated_order_verification_status] => SellingPartnerApi\Model\OrdersV0\UpdateVerificationStatusRequestBody Object ( [container:protected] => Array ( [status] => Approved [external_reviewer_id] => [rejection_reason_id] => )

            )

    )

)

My queries are:

1. How can I get this external_reviewer_id ?

2. I am getting this exception on running above code ? How to fix this exception? All of my credentials including token are correct.

SellingPartnerApi \ ApiException (403) [403] { "errors": [ { "message": "Access to requested resource is denied.", "code": "Unauthorized", "details": "" } ] }
