Updates the key-value store of custom publisher settings

Request Details

This API is designed to store publisher-specific values which can be read, but not written to, by the client. This data is shared across all titles assigned to a particular publisher, and can be used for cross-game coordination. Only titles assigned to a publisher can use this API. This operation is additive. If a Key does not exist in the current dataset, it will be added with the specified Value. If it already exists, the Value for that key will be overwritten with the new Value. For more information email
