Implementation with MQTT Only

When you use the feature of Thing Interaction Framework on things, you can call the API using MQTT only without HTTPS. On the other hand, you need to use HTTPS on mobile apps because the Kii Cloud SDKs do not provide MQTT communication for API call.

See the Thing Interaction Framework (Thing-IF) API reference for the APIs you can call via the MQTT protocol. The URL of those APIs starts with /thing-if/apps/{APP_ID}. The functions within the Kii Cloud SDK do not support API call via the MQTT protocol.

See Using API via MQTT to learn how to use the API via MQTT. The following topics explain how to establish an MQTT connection and how to call the API over the connection.
