The Intelligence setup distinguishes browser sign-in from API keys, because routing requires an interactive user with the route scope. Only an authorized OAuth user can place a referral with an eligible connected destination. Review provider discovery results and destination eligibility before asking the connected client to place a submission. Use the submission status tool to check the outcome, rather than assuming the referral was routed because a request was made. The app explains that submissions enter pending review and that API keys cannot route, keeping those outcomes distinct.
