Fixes DocuSign AUTHORIZATION_INVALID_TOKEN when a polling loop outlives the one-hour JWT access token - confirm expiry, add a refresh-on-401 wrapper, persist the polling cursor, and prefer Connect webhooks for events. Use when 401s start about an hour into a run. Not for first-request 401s or rate limiting.
For sales-outreach (SDR) agents: Treat auth as a lease that can die at any hour, not a one-time setup. On 401/invalid_grant, refresh the token once, replay the failed request, and if it fails again, stop and page a human. Retry loops on dead credentials burn quota and get accounts locked.
