Now Live! Cayenne REST API for application developers

Actually, there is a way. To send data using HTTP create a BYOT device then follow this:

curl --request POST \
  --url https://api.mydevices.com/things/THING_ID/data \
  --header 'authorization: Basic base64(MQTT_USERNAME:MQTT_PASSWORD)' \
  --header 'content-type: application/json' \
  --data '[
    {
        "channel": 100,
        "value": 27,
        "type": "temp",
        "unit": "c"
    }
]'
