BYOC Trunk Failover Logic via Platform API

How should I properly to programmatically update failover logic for active BYOC trunks using the Platform API? The PUT /api/v2/outbound/campaigns endpoint does not expose trunk failover parameters, and the documentation is silent on this specific configuration.

  • Attempted to patch the trunk configuration directly via PUT /api/v2/outbound/trunks/{trunkId}, but received a 405 Method Not Allowed.
  • Checked the Architect flow metadata for dynamic trunk selection, but that only applies to inbound routing, not outbound campaign failover.
