Call service endpoints over HTTP or HTTPS from Azure Logic Apps vs. request -response pattern

Question

Hi, I am trying to send the statuscode and/or output of the action (e.g., create file) to D365 FO. Our logic app workflows start with HTTP request trigger which is received from D365. which way is better among two approaches?:

1. HTTP request action (using custom service endpoint exposed by D365) vs.
2. request -Response pattern( like described in https://learn.microsoft.com/en-us/azure/connectors/connectors-native-reqres?tabs=standard#add-a-response-action.

If we use http request action using custom service endpoint for this purpose, does it cost extra everytime the logic app calls that service endpoint exposed from D365? Thank you.

Answer 1

I'm not familiar with how the D365 FO side of the equation works behind the scenes but if you can use the response from the Logic App from D365, then you should just use Response Action since that would be the simplest. But if that is not possible, or you are running into timeouts, then you should use the Request Action to call D365 from your Logic App. This is the same advice irrespective of whether you are using D365 to call Logic Apps or any other service.
