How to log the request received by WebApi's if it is exposed for third party system to consume?

Question

Hi, 
 
 We have Webapi's which are exposed to third party system to consume, I would like to know how to enable logs to know the request/response details which has been received/sent whenever the webapi is invoked by the third party system. 
 We are calling Expression Rules from our Webapi and not triggering any processes.

Hi Balaji.R, 
 
We have write to DB function available (a!writeToDataStoreEntity) to create an entry to DB on Interface or Web API. You can call this function before and after calling your web API body function to write Request & Response respectively. 
 
From DB perspective, you can create an audit structure table which can store both Request and response data.

Hi rp_balaji 
 
Adding to the suggestions provided by the practitioners. 
 
If you are only looking to debug the Request and Response then, 
 
Why don't you create and configure an Integration Object having the same service account details (provided to Third Party) configured and try invoking the Web-API to understand the Request and Response sent/received via this API. As you are aware that Integration Object acts like a Consumer and can consume an exposed Web Service (with-in or outside Appian Environment). 
 
Alternatively you can use other Third-party clients such as SOAP UI to understand the Request and Response Data and their format. 
 
NOTE: This approach is only applicable for Testing and debugging an API. And if these clients are able to consume and get the Response from your API then your Third Party Client should also be able to get the response as expected (if the configurations in the Client side are provided properly)
