Has anyone used an Azure Logic App or Azure Function with Telligent webhooks?

I experience inconsistent behavior when configuring a webhook to post to Azure Logic Apps and Azure Functions.

{
"events": [{
    "TypeId""<TypeId>",
    "DateOccurred""<DateOccurred>",
    "EventData": {
        "ActorUserId"<ActorUserId> ,
        "ContentId""<ContentId>",
        "ContentTypeId""<ContentTypeId>",
        "ForumReplyId"9999,
        "ForumThreadId"9999,
        "ForumId"<ForumId>
        }
    }]
}
Azure Logic Apps and Azure Functions both provide endpoints. I added these to Admin > Integrations > Webhooks in the Telligent Admin Console.
When I send this JSON from Postman to both a Logic App and Function, it is intercepted by both as expected.
When a webhook event is triggered, the Logic App successfully intercepts it.
When a webhook event is triggered, the Function app does not intercept it.
I am baffled and was curious if anyone else has encountered this.
This is for a Slack integration by the way
Thank you
