Deal Creation Webhook signature not matching with monitoring tab

[SayanGhosh]

I have set up a Deal creation webhook.  However, I am running into some strange errors. If I go to the webhook subscription details - then there is a test sample payload using which I can test. This is consistent with the webhook API doc.

[
{
"eventId": "100",
"subscriptionId": 1576318,
"portalId": 21920068,
"occurredAt": 1651922693081,
"subscriptionType": "deal.creation",
"attemptNumber": 0,
"objectId": 123,
"changeSource": "CRM",
"changeFlag": "NEW"
}
]

I can get the test to work with this. However, when I test my webhooks, they fail with 400 - and their signature is an object, not an array. Here's an example (its all from the test environment)

{
"eventId": 3569161897,
"subscriptionId": 1576318,
"portalId": 21924538,
"appId": 862032,
"occurredAt": 1651917294933,
"subscriptionType": "deal.creation",
"attemptNumber": 7,
"objectId": 8835693411,
"changeFlag": "NEW",
"changeSource": "CONTACTS"
}

Can anyone confirm which version is correct? I am doing a rather simple test with Power Automate and cannot seem to get it to work which is rather frustrating. Many thanks for any pointers.

Hey, @SayanGhosh 👋

To confirm, an array is the expected result here – it is possible to have multiple hook objects being delivered. 

@RMones and @rbthomas do you have any additional insight here?

Thank you! – Jaycee

Thanks @Jaycee_Lewis - that is helpful. The test webhooks are immediately firing 400 without reaching my server. Is there a way to use this test harness to use the right payload (postman works)? Can I just edit the payload to be an array on the textbox in the portal (would have to check if it's editable) and try?

Seems like the webhooks test harness is now fixed, thanks!
