Process model - Web Api

Good morning,

We have the need to set up an integration to call us and return a response from a file.

We are creating a WebApi that receives an XML and raises a processModel, does the validations and returns the response.

The problem is when we have to make that it does not exceed 20 seconds. We are putting a control timer, but this timer makes that when calling the WebApi it finishes without waiting the 20 seconds.

Thank you

Alex
