Azure Logic App not posting dynamic content of message in Slack/Teams

Question

I have established an integration between Azure Logic App and Slack Channel for posting the Azure Service Health Alert to the Slack Channel.

Logic App Designer :

• I am using HTTP trigger -> template from MS doc (https://learn.microsoft.com/en-us/azure/azure-monitor/alerts/alerts-common-schema-definitions ) for JSON payload schema .
• Have made sure Common Alert Schema is enabled on the respective Action Group
• I was able to establish the connection between Teams & Slack Channel for posting the Message.
• In the Message Body I am using combination of Static and Dynamic Contents
• However when the Alert is triggered to Slack and Teams Channel I see the Dynamic Content values are missing (as if passed null) , for eg. for Title : <title_dynamic_content> it only post "Title :"

could someone please help ?

@Rajesh Kumar Mishra If the value is coming null then the Request Body JSON schema would be incorrect thereforethe value are not captured correctly. The suggestion would be use the body value in your screenshoot to generate the schema using the Use sample payload to generate schema option of your Request trigger

If your generated schema matches the request body that you are sending then the value should be assigned correctly as in the below image when I navigate to the run history

As I have tested with the below sample json input you will not see all the fields as per your screenshoot. You can use the body value of your request and then generate the right schema.

{  
   "schemaId":"azureMonitorCommonAlertSchema",  
   "data":{  
      "essentials":{  
         "alert ID":"/subscriptions/guid",  
         "alertRule":"test",  
         "severity":"Sev4",  
         "signalType":"Activity Log",  
         "monitorCondition":"Fired",  
         "monitoringService":"ServiceHealth",  
         "alertTargetIDs":[  
            "/subscriptiions/subscriptionID"  
         ],  
         "originAlertId":"newid",  
         "firedDateTime":"2021-10-02T00:40:03.7826873",  
         "description":"Security advisor",  
         "essentialsVersion":"1.0",  
         "alertContextVersion":"1.0"  
      },  
      "alertContext":{  
         "authorization":null,  
         "channels":1,  
         "propeties":{  
            "title":"RCA etc"  
         }  
      }  
   }  
}
