Can I run SignalR hub through Azure API Management?

Question

I have the same question as this guy: can I run my SignalR hub through the Azure API management service?

I cannot seem to configure it in the service: it only allows me to forward HTTP/HTTPS traffic. That matches the answer of the person in the forum post. I followed the link down to the Microsoft forum, but it seems the question wasn't followed up there. Since the response was from 2014, I thought - maybe it is possible now.

Answer 1

websocket is currently not supported in Azure API Management. Please feel free to raise a feature request: http://feedback.azure.com/forums/248703-api-management/filters/new

Answer 2

As we know, the Azure API Management still doesn't support WebSockets

Rest assured we still have this request in mind and are continually reviewing it. Please keep your feedback coming!

If you are using Azure SignalR Service then you can follow the way described by @lazizanie because your SignalR service should only provide a negotiate endpoint:

Let's say you have the Hub named myHub in ASP.NET Core 3.1

app.UseEndpoints(endpoints => endpoints.MapHub<Hub>("/myHub"));

Then add operation in API management URL=POST /myHub/negotiate with negotiateVersion query param

or use JSON editor and add it to paths

"/myHub/negotiate": {
    "post": {
        "summary": "SignalR negotiate ",
        "operationId": "signalr-negotiate",
        "parameters": [{
            "name": "negotiateVersion",
            "in": "query",
            "schema": {
                "type": ""
            }
        }],
        "responses": {
            "200": {
                "description": null
            }
        }
    }
}
