Inbound event helpers for channel plugins: context building, shared runner orchestration, session record, and prepared reply dispatch	Channel inbound API	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 receive paths follow one flow:

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

import {
  buildChannelInboundEventContext,
  runChannelInboundEvent,
  dispatchChannelInboundReply,
} from "openclaw/plugin-sdk/channel-inbound";

• buildChannelInboundEventContext(...): projects normalized channel facts into the prompt/session context. Pass channel-owned sender/chat metadata through channelContext, which plugin hooks see as ctx.channelContext. Augment PluginHookChannelSenderContext or PluginHookChannelChatContext from this subpath for channel-specific fields.
• runChannelInboundEvent(...): runs ingest, classify, preflight, resolve, record, dispatch, and finalize for one inbound platform event.
• dispatchChannelInboundReply(...): records and dispatches an already assembled inbound reply with a delivery adapter.

Bundled/native channels that already receive the injected plugin runtime object can call the same helpers under runtime.channel.inbound.* instead of importing this subpath directly:

await runtime.channel.inbound.run({
  channel: "demo",
  accountId,
  raw: platformEvent,
  adapter: {
    ingest: normalizePlatformEvent,
    resolveTurn: resolveInboundReply,
  },
});

Assemble dispatchChannelInboundReply(...) inputs for compatibility dispatchers that keep platform delivery in the delivery adapter. New send paths should use message adapters and durable message helpers from channel-outbound instead.

Migration

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(...), deprecated, 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.
