The idea here is to have a mechanism to validate the data and throw an appropriate response with message, before without the data is being persisted in the database. This validation check is not meant to be limited for to new data but should also extend to sub-sets of a larger data set, such as data used in case of an update operation. So based on this the following approaches are proposed to perform a validation on data:

...

• Response Code: 400
• Response Body: a JSON response providing details about the failure. (response body format to be finalized)
