How to monitor incoming messages to ION API gateway in MT

David TOLLET

Dear Community,

Is there a way to more precisely monitor incoming request coming to the ION API gateway. 

My issue is the following : 

I'm trying to make an external application ;communicating with ION API gateway using IMS v3 multipart endpoint. When testing this I get a 400 - Bad request response with error message detail saying that "Empty request body not allowed". I can see the error in ION API monitoring. The authorization process is running correctly, I succesfully get the OAuth 2.0 token, this is the IMS endpoint which is falling.

When do the same request within Postman, with the same message Payload and ParameterRequest, I succesfully get the "202 - The request was processed successfully" response. 

So I suspecting something is wrong in the HTTP call my external application is doing. Maybe something wrong in the header information but I'm unable to see the exact HTTP call my application is sending to ION API gateway. ION API monitoring is giving very poor information.

Is there a way to get the exact HTTP frame the ION API gateway is receiving ?

Many thanks for your help.

you can try add request body parameter for this end point in swagger document and then re-configure the API call in connection point. see if it help.
