# Event-driven partner integrations at scale

How to onboard partners in hours instead of months using a unified event delivery layer.

Every SaaS platform eventually needs partner integrations. And every platform learns the hard way that point-to-point integrations don't scale.

## The problem with point-to-point

Partner A wants webhooks. Partner B wants a REST API. Partner C wants events in a Kafka topic. Partner D wants... well, they're not sure yet, but they need it by Friday.

Each integration becomes a custom project. Your engineering team spends more time building integrations than building product. Sound familiar?

## The event delivery approach

Instead of building N custom integrations, build one: emit events to a transport layer. The transport layer handles the rest.

With Queuey, the workflow looks like this:

1. **Your service emits events** to Queuey using a simple HTTP API
2. **Queuey stores and routes** events based on configurable rules
3. **Each partner gets events** in their preferred format and protocol

## Per-partner configuration

The real power is in per-partner customization without code changes:

- **Protocol**: Webhooks, REST polling, WebSocket, or MCP
- **Format**: JSON, XML, Protocol Buffers, or custom transformations
- **Filtering**: Each partner only gets the events they care about
- **Rate limiting**: Protect partners from event storms
- **Authentication**: OAuth, API keys, HMAC signatures — per partner

## Onboarding in hours

When a new partner joins, you don't write code. You configure a routing rule. Define what events they should receive, in what format, to what endpoint. Deploy. Done.

We've seen teams go from "first conversation" to "events flowing" in under 4 hours. That's the power of a proper event delivery layer.
