NewHow the Agent Session Protocol builds trust between autonomous systems.
Use Case

Event driven architecture

Guaranteed event delivery across every system, every organization, every boundary.

A system publishes an event.

Ten services need it. Three partners need it.

An internal service gets it. The partner does not.

Nobody notices until a customer complains.

Your team builds retry logic for one connection.

Then ordering. Then failure queues. Then cross org consent.

Months pass. You are still building plumbing.

npayload delivers across every boundary from day one.

See how it flows

Events cross every boundary

Internal microservices, autonomous agents, external partners. Publish once. npayload delivers across service boundaries, org boundaries, and regional boundaries with the same guarantee.

Event Stream

#314:22:08.203inventory.reserved
#414:22:08.298shipment.dispatched
#514:22:08.344notification.sent
Strict ordering guaranteed

Ordering and streams

Message groups ensure FIFO ordering. Streams let consumers replay from any offset. Consumer groups distribute load. Priority queues accelerate critical events.

Zero infrastructure

No brokers to deploy. No partitions to manage. No clusters to scale. npayload's cell architecture handles all of it, including cross region replication.

How it works

1

Create channels

Define event channels with privacy mode, delivery preferences, and encryption level. One channel can reach internal services and external partners alike.

2

Publish and subscribe

Any system publishes events. Internal services, autonomous agents, and external organizations subscribe with independent delivery guarantees.

3

Scale across every boundary

npayload handles retries, circuit breakers, cross org consent, regional routing, and dead letter queues. You focus on business logic.

Event Driven Architecture: Before and After

Without npayload

  • Events stop at the org boundary. Internal events never reach external partners without custom pipelines
  • Every new partner connection requires months of integration work: retries, auth, ordering, compliance
  • No guaranteed delivery across boundaries means events are lost during outages, deployments, and network failures
  • Event schemas drift between systems. No central catalogue, no versioning, no compatibility checks
  • Debugging event flows across internal services, agents, and external partners is nearly impossible

With npayload

  • Events cross every boundary: internal services, autonomous agents, external organizations. Publish once, deliver everywhere
  • New partners subscribe through npayload with consent, encryption, and audit. Minutes, not months
  • Guaranteed delivery with DLQ, circuit breakers, and automatic retries across every connection
  • Event catalogue provides schema registry with versioning, compatibility validation, and cross org discovery
  • W3C distributed tracing follows every event across every system, every org, every region automatically

Frequently asked questions

How does npayload compare to Kafka or RabbitMQ?+
npayload provides the same messaging primitives (pub/sub, consumer groups, streams, DLQ) without the operational burden. But it goes further: cross org delivery with consent, three privacy modes including zero knowledge encryption, and a built in event catalogue. Kafka and RabbitMQ are internal tools. npayload works across organizational boundaries.
Can npayload deliver events to external organizations?+
Yes. This is a core strength. Events cross org boundaries with consent based sharing, encryption, and full audit trails. External partners subscribe the same way internal services do. No custom integrations needed.
Does npayload support exactly once delivery?+
Yes. Delivery tokens provide exactly once semantics at the consumer level. Each delivery includes a unique token that consumers check before processing, preventing duplicate handling.
Can autonomous agents use npayload for event driven communication?+
Absolutely. npayload's ASP (Agent Session Protocol) provides structured sessions for agent to agent communication, and the underlying event infrastructure delivers messages between agents with the same guarantees as any other subscriber.
Can I migrate from Kafka or RabbitMQ?+
npayload provides native adapters for Kafka, SQS, Pub/Sub, EventBridge, Azure Service Bus, and more. Run both in parallel during migration. Keep your internal broker and add npayload for cross org, encryption, and compliance.
What about data residency and compliance?+
npayload's cell architecture keeps data in the region your compliance team requires. Cross border transfers require explicit consent. SOC 2, GDPR, HIPAA, and ISO 27001 controls are built in.
