sandbox_key_restricted

This sandbox key came from anonymous sign-up: it may manage its sandbox accounts, trade, stream and read, nothing else.

HTTP 403. Nothing reached the broker.

Likely causes:

• Creating a webhook, pre-trade hook, agent key, API key or token, or another sandbox key with a key from POST /v1/sandbox/signup.
• Creating, changing or deleting a risk-management tracker or guard rule (or resetting trading statistics) with such a key. Reading trackers, statistics and metrics stays allowed.
• A sandbox key whose restrictions we could not confirm, on a risk-management write (it fails closed).

What to do: Sign in, then create a sandbox key with POST /v1/sandbox/keys using your live key; it has full rights inside your sandbox.

Retry: No. The same request gets the same answer; change something first.
