Message

This API key does not have write scope. Mint a new key with read_write scope under /developers in the app.

​
Common cause

You called PATCH /v1/sensors/{id} (the only write endpoint in V1) with a key that was minted as Read only. Read keys can list sensors and pull readings but cannot update sensor names or metadata.

​
Fix

Mint a new key under Integrations → API access with Read and write scope. Use that key for any code path that calls PATCH. Keep your existing read-only keys for pure-read integrations (Sheets dashboards, monitoring scripts) — they’re safer to leak because they can’t mutate anything. If you want one key to handle both read and write workloads, mint with Read and write. The expanded scope still respects rate limits and the per-key audit log.
