On an INSERT statement, the only way to not have concurrency is to violate some kind of constraint. As long as you have declared the constraint (primary key, not null, foreign key, etc), the database will throw an error on any violation.
I’m not sure what API you are using to talk to the database, but it will certainly signal in some way that a database error has occurred. Then you need to handle that case appropriately by informing the application to invalidate the data.
