What is the correct approach to push contact lists into the outbound dialer without triggering rate limits? The external list manager keeps failing on the /api/v2/outbound/contactlists endpoint every Tuesday at 08:45 PT. Campaign kickoff gets pushed back again. Management wants the 12,000 records active before the shift starts. Vendor support doesn’t send back much help. Tried breaking the upload into smaller batches but the progress bar does jack all. System keeps throwing a 429 Too Many Requests error with a retry after value of 180 seconds. Vendor tool runs on Genesys SDK v2.4.1 and the Architect flow triggers a contact list lookup before the dial attempt. Dialer sits completely idle while agents just sit there refreshing their screens. Queue metrics drop to zero. How do I adjust the authentication token or set up a proper retry mechanism? The external dashboard just flashes red. Logs point to a scope mismatch on the integration user. Payload structure looks off. Vendor keeps saying it’s a Genesys side issue.
