Systems and techniques that facilitate centralized request validation are provided. In various embodiments, a central validation server can comprise an input component. In various cases, the input component can receive a validation instruction from a gateway service. In various aspects, the validation instruction can be based on a request received by the gateway service from a client. In various instances, the request can be handleable by an operational flow path through a plurality of domain services that are downstream of the gateway service. In various embodiments, the central validation server can comprise a central validation specification component. In various aspects, the central validation specification component can store a plurality of request validation specifications respectively corresponding to the plurality of domain services. In various embodiments, the central validation server can comprise an output component. In various instances, the output component can transmit, in response to the validation instruction, the plurality of request validation specifications to the gateway service. In various aspects, the gateway service can validate the request based on the plurality of request validation specifications. In various embodiments, the gateway service can determine that the request fails to satisfy at least one of the plurality of request validation specifications. In various cases, the gateway service can return an error to the client without invoking any of the plurality of domain services.
