When a user has a completed application and would like to submit it to receive refinancing offers, send a POST request with the applicationId in the body. Once an application is submitted, to preserve data fidelity, it can no longer be altered. The response will contain a copy of the application you just submitted which will now contain a value for the appliedOn field. It is important to remember that this submission initiates an asynchronous request to all the refinancing servicers, and as those requests are fulfilled, they will be returned with a call to the results API.
