Rejectar

Rejectar is a term used in software development to describe the component, function, or mechanism that enforces the rejection of invalid inputs or requests within a system’s validation or moderation workflow. It is a coined form of the verb reject with the suffix -ar, and appears in some technical discussions to emphasize the act of denying an input rather than modifying it.

Definition and role. In practice, a rejectar applies predefined rules, checks formats, permissions, and business constraints, and then returns an error response or blocks further processing. It operates alongside validators that might correct or inform users, but its function is strictly to halt or reject nonconforming inputs when they fail policy checks.

Usage contexts. It is commonly used in form validation, API gateways, and content moderation pipelines, where fast rejection helps prevent downstream errors, reduce load, or enforce policy. In some architectures, the rejectar is implemented as a dedicated service or as a module within a validation layer.

Variants and naming. Other terms used for similar roles include rejecter, rejection gate, or simply the validation layer. Some teams treat rejectar as a project name or a specific module; usage varies across organizations and documentation.
