servervalidated

Servervalidated is a term used in software engineering to indicate that an input, parameter, or value has been validated on the server. It is typically used in API documentation, contract definitions, or code comments to differentiate between validations performed on the client (in the browser or app) and those performed on the server after submission. The label is not a formal standard; its usage varies by project and language. The key idea is that the server side enforces rules such as data types, required presence, format validity, value ranges, and cross-field constraints, and may perform lookups or uniqueness checks against a database before proceeding with processing.

In practice, a servervalidated input may be accompanied by a server-side validation outcome or errors when invalid. Client applications should not rely on client-side checks alone; server validation is essential for security and data integrity because client-side checks can be bypassed. Implementation typically involves receiving input, running validation logic via server-side frameworks or libraries, and returning structured error responses (for example, an HTTP 400 with error details) if validation fails. If the data passes, the server continues with business logic and operations such as storage or processing.

Terminology: Some teams prefer the hyphenated form “server-side validated” or “server-validated” and avoid the single-word form. The term is most useful as a communication cue rather than a formal concept; it signals that validation was performed in a trusted server environment.
