SymptomLogin pages, CAPTCHAs and human-verification interstitials interrupt an otherwise automated workflow. In the Shopify case the login was completely unusable.
CauseThe agent computer browses from datacenter IP addresses with a bot-flagged fingerprint, which anti-bot systems such as Cloudflare and hCaptcha reject.
DetectionThe Bot is expected to ask for takeover, but that handoff is not reliable; the Suno case shows the takeover completing and the action still failing silently.
FixDesign a fallback for every hostile site: official API, vendor connector, or a manual escalation path. Vendor staff prescribed exactly this for Shopify, recommending an Admin API access token instead of the login page. Follow the general interface hierarchy of structured plugin, then official API or CLI, then cloud browser, then local computer.
