How would you describe data mapping in the context of this API?

Data mapping in API setup is the process of matching data from external sources or formats with the internal structures and models of the system. For example, if an API accepts JSON with a specific structure, mapping describes how the fields of this JSON are transformed into database objects or records.

In API setup, it is important to:

• Define the correspondence between input data fields and model fields.
• Handle type conversions (e.g., string to date).
• Consider required and optional fields.
• Ensure validation and error handling.

This helps guarantee that data received through the API is correctly interpreted and used by the system.
