summary: "Inbound event helpers for channel plugins: context building, shared runner orchestration, session record, and prepared reply dispatch"
title: "Channel inbound API"
read_when:
- You are building or refactoring a messaging channel plugin receive path
- You need shared inbound context construction, session recording, or prepared reply dispatch
- You are migrating old channel turn helpers to inbound/message APIs
---
Channel plugins should model receive paths with inbound and message nouns:
```text
platform event -> inbound facts/context -> agent reply -> message delivery
```
Use `openclaw/plugin-sdk/channel-inbound` for inbound event normalization,
formatting, roots, and orchestration. Use
`openclaw/plugin-sdk/channel-outbound` for native
send, receipt, durable delivery, and live preview behavior.
## Core Helpers
```ts
import {
buildChannelInboundEventContext,
runChannelInboundEvent,
dispatchChannelInboundReply,
} from "openclaw/plugin-sdk/channel-inbound";
```
- `buildChannelInboundEventContext(...)`: project normalized channel facts into
the prompt/session context.
- `runChannelInboundEvent(...)`: run ingest, classify, preflight, resolve,
record, dispatch, and finalize for one inbound platform event.
- `dispatchChannelInboundReply(...)`: record and dispatch an already assembled
inbound reply with a delivery adapter.
The injected plugin runtime exposes the same high-level helpers under
`runtime.channel.inbound.*` for bundled/native channels that already receive the
runtime object.
```ts
await runtime.channel.inbound.run({
channel: "demo",
accountId,
raw: platformEvent,
adapter: {
ingest: normalizePlatformEvent,
resolveTurn: resolveInboundReply,
},
});
```
Compatibility dispatchers should assemble `dispatchChannelInboundReply(...)`
inputs and keep platform delivery in the delivery adapter. New send paths should
prefer message adapters and durable message helpers.
## Migration
The old `runtime.channel.turn.*` runtime aliases were removed. Use:
- `runtime.channel.inbound.run(...)` for raw inbound events.
- `runtime.channel.inbound.dispatchReply(...)` for assembled reply contexts.
- `runtime.channel.inbound.buildContext(...)` for inbound context payloads.
- `runtime.channel.inbound.runPreparedReply(...)` only for channel-owned prepared
dispatch paths that already assemble their own dispatch closure.
New plugin code should not introduce `turn`-named channel APIs. Keep model or
agent turn vocabulary inside agent/provider code; channel plugins use inbound,
message, delivery, and reply terms.
