Various embodiments describe methods, systems, and devices for client-driven dynamic server-side configuration validation. Exemplary implementations may include validating client device configuration data, updating a client device shadow with the validated client device configuration data, in which the client device shadow includes a schema in a client device-agnostic language, and translating client device configuration data of the client device shadow from the client device-agnostic language to a client device-specific language. Also, receiving the client device configuration data from a computing device over a communication network, and sending the client device configuration data of the client device shadow in the client device-specific language to a client device via a communication network. Further, translating a client device schema from the client device-specific language to the client device-agnostic language, identifying differences in the client device schema from the schema of the client device shadow, and updating the client device shadow with the differences.
