Can anyone clarify the correct payload structure for POST /api/v2/outbound/campaigns when initializing campaigns across multiple organizations via a Premium AppFoundry integration? The API consistently returns a 400 Bad Request with a generic ‘invalid_request’ error code, despite the request adhering to the documented schema for single-org setups. Environment details include Genesys Cloud v2023.10, OAuth 2.0 client credentials flow, and a multi-tenant architecture handling high-volume outbound operations. The issue persists even when isolating the request to a single test organization, suggesting a potential mismatch in expected fields for multi-org contexts.
