Managing idempotent operations is provided. A request to perform an operation on a system of record is received from a client via a network. An idempotency resolver is queried to determine whether a result corresponding to the operation is located in a mapping table of the idempotency resolver. In response to determining that the result corresponding to the operation is in the mapping table of the idempotency resolver, the result corresponding to the operation that is located in the mapping table of the idempotency resolver is sent to the client via the network.
