Sentin8:Post — Multi-Channel Message Delivery

Outbound messaging: email, SMS, push notifications, and webhooks — templated, tenant-branded, idempotent, retry-scheduled. One send API, every channel; delivery failures queue and retry, never silently drop.

Use cases

• Transactional notifications — a payment confirmation, a reservation reminder, a trade alert: one send call, the channel routes per tenant preference.
• Webhooks for third parties — signed webhook delivery with retry and DLQ semantics for external consumers.
• Branded templates — per-org/per-env branding resolves through the platform's branding chain (org base → env override).
• SSE inbox feed — apps subscribe to live notification streams over /subscribe (the one-way tier).
