Overview

A client-mode connector for a curated cloud-IoT slice of ChirpStack v4 covering these connector events. ChirpStack v4 does not ship a built-in REST API — use chirpstack-rest-api (gRPC gateway), typically on port 8090. Default BASE_ADDRESS is https://localhost:8090 (no trailing slash; substitute https://{host}:8090). Topics use cloud-iot/chirpstack-v4/<object>/<verb>. See the base guide: REST API Connectors.
Auth header: Pass the full Authorization value via MQTT JSON field authorization as Bearer {api_token} (ChirpStack API key / JWT). Prefer Hub secrets (CHIRPSTACK_AUTH). Never commit real credentials. Some deployments also accept Grpc-Metadata-Authorization: Bearer …. See the REST API notes and API reference.
