Two integration surfaces: request/response and event-driven
A platform integration generally needs two distinct patterns: a request/response API for a calling system to ask a question or trigger an action directly (look up a conversation, initiate an outbound action), and an event-driven layer for the platform to notify external systems when something happens on its own timeline (a call completes, a conversation is assigned, a compliance gate blocks a dial attempt). Voz360’s architecture provides both, and understanding which pattern fits a given integration need is the first design decision, before any endpoint-level detail.
Authentication and permission scoping
API access is scoped by the same role-based permission model used inside the platform itself — a request is checked against the calling identity’s permission bundle before it is allowed to act, the same pre-handler pattern used for every protected internal route. This means an integration credential can be scoped as narrowly as the use case requires (read-only access to conversation metadata, for example) rather than granted broad platform access by default, which matters directly to a security team reviewing what a third-party integration can actually reach.
Predictable error handling: a technical evaluator should expect this from any serious API
A well-designed API returns structured, predictable errors — a consistent shape for validation failures, permission denials, and not-found conditions — rather than inconsistent ad hoc error formats that force every integrating system to special-case each failure mode. Predictable error handling is what lets an integrating engineer build reliable retry and fallback logic without guessing at undocumented edge cases; it is a baseline expectation for evaluating any platform’s API maturity, not unique to Voz360.
The event-driven pattern: schema-validated, tenant-checked, retried, and dead-lettered
When platform state changes in a way an integrating system needs to know about, Voz360’s architecture writes that change as a validated event rather than publishing directly and hoping a downstream consumer catches it. Each event is schema-validated against a defined contract, checked against the originating tenant’s boundary before it is emitted, and delivered with retry logic if the first delivery attempt fails. Events that continue to fail delivery after retries are routed to a dead-letter path rather than silently discarded, so a delivery failure is visible and recoverable instead of a quiet data-loss event.
Idempotency: why a retried event should never double-process
Because retries are part of the delivery design, a receiving system needs a way to recognize "I already processed this" and skip duplicate processing on a redelivered event — this is the idempotency concern that any event-driven integration has to solve on both sides. Voz360’s event design carries the identifiers needed for a receiving system to implement idempotent handling; the receiving system still has to actually implement that check, which is a standard integration responsibility, not something a sending platform can fully solve unilaterally.
What this page is not: a public API reference
This is an architecture-level explainer of the patterns Voz360’s API and event layer follows — authentication and permission scoping, structured error handling, schema-validated and retried event delivery, dead-letter handling, and idempotency design — intended to help a technical evaluator understand what to expect before a deeper technical discovery conversation. Specific endpoint names, request/response payload schemas, and SDK availability are scoped during that discovery conversation, not published here.
