Integrations & system health

The platform never becomes a new source of truth. NFSA and State PDS own beneficiary data; UIDAI owns identity; AePDS owns lifting. This system reconciles and reflects them — all egress is via the Istio mesh over mTLS, and every adapter has a dead-letter queue fallback.

Dead-letter queue

Failed messages held for idempotent replay — never silently dropped

India Post · delivery webhook

Talode pkt-3 · timeout, retry 2 of 3

India Post · delivery webhook

Talode pkt-7 · timeout, retry 1 of 3

India Post · delivery webhook

Talode pkt-9 · timeout, retry 1 of 3

Retried sync is idempotent — replays never double-count in the trace ledger.
