30993: Campaign Registration Failed

Twilio returns this error when a campaign's Connectivity Partner CNP migration does not complete within the expected timeframe, indicating the external campaign association and approvals did not finalize.

• Required secondary DCA reviews or carrier specific approvals in the CNP migration chain are still pending, so the migration cannot complete.
• The external campaign association has not reached a verified state yet, so the campaign remains unready to send.
• The associated external campaign API call exceeded its rate limit and the asynchronous retries exhausted, moving the campaign to a failed status.

• Confirm all CNP migration approvals are complete and verify the campaign is ready by fetching campaign details and ensuring the campaign status is verified before sending.
• If the association failed due to rate limiting or similar asynchronous failure, delete the external campaign association in Twilio, reshare the campaign to Twilio via TCR, then re associate it.
• When migrating via CNP, set the CnpMigration parameter accordingly when associating the external campaign with a Twilio Messaging Service.
• For best results, migrate numbers first and ensure SMS traffic is active on Twilio for the ported numbers before starting campaign migration.
• If vetting remains in progress beyond typical review windows and the migration still does not complete, contact Twilio Support for assistance.
