All paths share credits, consent, and Trust Setup. Prefer A2A for new integrations.

## Decision tree

1. Do you onboard **many** end-customers who each need isolated SMS? → **Partner**
2. One company pulling CRM audiences? → **Enterprise sources**
3. Pure automation / AI agent? → **A2A RPC** (+ Agent Gateway portal)
4. Marketer in the UI? → **Operator Studio**
