Chat SDK now ships the Slack adapter 's primitives as standalone imports for apps that already handle their own routing, state, or workflow execution.

Use only what you need:

Request verification and payload parsing ( @chat-adapter/slack/webhook )

Markdown formatting ( @chat-adapter/slack/format )

Fetch-based Web API calls ( @chat-adapter/slack/api )

Block Kit conversion ( @chat-adapter/slack/blocks )

Each subpath skips the full Chat runtime, so your imports stay clean.

import { readSlackWebhook } from "@chat-adapter/slack/webhook" ;

import { postSlackMessage } from "@chat-adapter/slack/api" ;

export async function POST ( request : Request ) {

const payload = await readSlackWebhook ( request , {

signingSecret : process . env . SLACK_SIGNING_SECRET ! ,

} ) ;

if ( payload . kind === "app_mention" ) {

await postSlackMessage ( {

channel : payload . continuation . channelId ,

markdownText : ` received: ${ payload . text } ` ,

token : process . env . SLACK_BOT_TOKEN !…
