Notification API - Create Destination

[vinyliebhaberei!]

Hello,

I am trying to create a destination like it is shown in the example:

{
"name": "api_destination",
"status": "DISABLED",
"deliveryConfig": {
"endpoint": "https://e***********4.s*************.com/notification-endpoint",
"verificationToken": "7*******-d***-***c-b***-***********a"
}
}

mywebhook.php is sending:

if (isset($_GET['challenge_code'])) {
$expectedVerificationToken = '7*******-d***-***c-b***-***********a';

header('Content-Type: application/json');
http_response_code(200);
echo json_encode(['challengeResponse' => $expectedVerificationToken]);
}

But all I ever get in return is:

{
"errors": [
{
"errorId": 195020,
"domain": "API_NOTIFICATION",
"category": "REQUEST",
"message": "Challenge verification failed for requested endpoint."
}
]
}

Could anybody please tell me what I am doing wrong. As I understand it, I need to send the expected token back just as it was sent.

Thank you for your help
Axel

hey did you have any luck with this? The documentation is so poor for challenge verification.

@vinyliebhaberei! just tagging you for above question ^^

Refer to this document: https://developer.ebay.com/api-docs/commerce/notification/overview.html#create-destination. You need to respond with the hashed string generated from the combination of challengeCode, verificationToken, and endpoint.
