No terminal that could route your request is currently able to perform the operation you asked for — distinct from a card decline, which always requires a live terminal to have been reached in the first place.
TL;DR — resolution: "operator" means a configuration change is needed, not a retry. Contact support with the request_id.

When this happens

  • Every candidate terminal has the requested operation toggled off — 409 urn:radiumone:routing:operation-disabled (resolution: operator).
  • No usable terminal could be routed for the channel/acquirer/currency at all — 409 urn:radiumone:routing:no-device-available (resolution: operator).
  • Every candidate terminal exists but isn’t ACTIVE — 409 urn:radiumone:routing:terminal-inactive (resolution: operator).
  • The one terminal that was routed has this specific operation toggled off at the device level — 422 urn:radiumone:device:operation-not-supported.
  • A follow-up operation (capture/void/refund) inherits its acquirer channel from the original transaction, and that channel doesn’t have the operation enabled — 422 urn:radiumone:routing:capability-not-supported. This is the error you’ll see if you attempt a refund before requesting enablement, since refunds are disabled by default.

What you see

What to do

1

Don't retry the same call

None of these clear on their own or with backoff — a resolution: operator conflict needs a configuration change, not a retry.
2

Contact support with the request_id

Contact support with the failing operation and the request_id from the response, so they can check enablement for your outlet/terminal.
3

Confirm enablement before you rely on an operation in production

Card is enabled by default; every other operation and payment method requires explicit enablement — see Payment methods: enablement and work through the go-live checklist before launch.
