Azure API Management Not Routing to Backend Service After Deployment

I've been struggling with this for a few days now and could really use some help. I'm stuck on something that should probably be simple. I'm working with an scenario with Azure API Management (APIM) where my newly deployed API is not routing requests to the backend service. Here's the configuration I used for the API: ```json { "properties": { "displayName": "My API", "serviceUrl": "https://my-backend-service.azurewebsites.net", "path": "myapi", "protocols": ["https"], "apiVersion": "v1" } } ``` After deploying this configuration, when I try to access the endpoint `https://<your-apim-name>.azure-api.net/myapi`, I receive a `404 Not Found` behavior, and the logs indicate that the request is not reaching my backend service. I verified that the backend service URL is correct and accessible directly via a browser. I also checked the following: 1. The backend service is running and has no issues. 2. The API Management instance is set to route requests appropriately in the Azure Portal settings. 3. The `CORS` policy is correctly set to allow requests. 4. The API is published and not in draft mode. I tried adding a simple policy to log the incoming requests: ```xml <inbound> <base /> <log-to-eventhub eventHubName="myEventHub" connectionString="<connection-string>" /> </inbound> ``` But I'm not seeing any logs, which leads me to believe the requests aren’t even hitting the APIM instance. Can anyone guide to troubleshoot this? Is there a step I might have missed in the APIM setup or any specific configurations related to routing that I should check? I'm using Azure API Management v3. I'm working on a application that needs to handle this. Any help would be greatly appreciated! Thanks in advance! Any examples would be super helpful.
