# API - May 4, 2022 - Cyclamen

Added

### Birthday can no longer be set in the future

Setting the user `Birthday` or `LegalRepresentativeBirthday` parameter to a date falling after today’s date is no longer possible.

If such an update were to be attempted, the API would return a Status 400 error, stating that the `Birthday` cannot be in the future.

The following API endpoints have been updated to take this change into account:\
-Create a Natural User\
-Update a Natural User\
-Create a Legal User\
-Update a Legal User\
-View a User

This enhancement aims at improving the overall data quality of the Mangopay API.\


Changed

### Error message for KYC Document creation

Attempting to create a KYC Document for a user that is not created yet now returns a Status 400 error, stating that the `UserID` value is invalid.

The platform should then retry to create the KYC Document, once the user creation has been completed.

This change aims at clarifying the API behavior.
