- Define versioned journey configurations, transition rules, policies and state-specific response guidance.
- Ensure the Gateway validates actions proposed by an agent against current state, identity, authorization and business rules.
- Develop adapters for customer backend systems using approved API contracts.
- Implement timeouts, retries, idempotency, concurrency controls and recovery from partial failures.
- Persist session state and audit records with appropriate isolation, retention and protection of customer data.
- Implement authentication, authorization, secrets management and service-to-service security.
