Main Features
Send messages in a few lines with postChatMessage
Posting to Slack requires only a token, channel ID, and text; no manual UrlFetchApp code is needed.
Supports rich messages (attachments)
Allows sending richly formatted notifications by passing an attachments option with colors and fields.
Direct access to WebClient
createWebClient exposes a method set similar to Slack's official Web API, enabling fine-grained endpoint calls.
TypeScript type definitions
Copying the provided d.ts file gives autocomplete and type checking in TypeScript projects.
Usage Examples
Send a simple Slack message
function sendSimpleSlackMessage() {
const token = 'xoxb-your-token'; // Bot or user token
const channelId = '#general'; // Target channel
const text = 'Hello from Google Apps Script!';
// Use helper to post the message
SlackWebApi.postChatMessage(token, channelId, text);
}The helper abstracts away UrlFetchApp calls; supplying token, channel, and text is enough to post a message.
