Variables

Variables store key–value metadata on a device (a location, calibration offset, asset number …) — useful to read inside a connector's transformation function.

Create a variable — POST /v2/spaces/{space_id}/variables:

curl -X POST \
  -H 'X-API-KEY: <api-key>' \
  -H 'Content-Type: application/json' \
  'https://api.hardwario.cloud/v2/spaces/<space-id>/variables' \
  -d '{
    "device_id": "<device-id>",
    "name": "location",
    "value": "warehouse-A-shelf-3"
  }'

List and filter with GET …/variables?device_id=<device-id> (also name, environment, secure). Manage a single variable with GET/PUT/DELETE …/variables/{id}, and pin values with …/variables/{id}/lock and /unlock.
