Google Chat Messages

Sends messages to Google Chat spaces via incoming webhooks, handling text, cardsV2, and threaded replies. Comes with TypeScript utilities for building cards and a complete widget reference, including decoratedText for key-value pairs, buttonList for actions, and collapsible sections. The formatting guide is legitimately helpful since Google Chat uses its own syntax (*bold*, _italic_) instead of standard Markdown, which trips people up constantly. Use this when you're scripting notifications, building status cards with actual structure, or need to thread related updates together. The card builder removes most of the JSON wrestling, and the known icon list saves you from hunting through Google's docs.

Google Chat Messages

Send messages to Google Chat spaces via incoming webhooks. Produces text messages, rich cards (cardsV2), and threaded replies.

What You Produce

Text messages with Google Chat formatting
Rich card messages (cardsV2) with headers, sections, widgets
Threaded conversations
Reusable webhook sender utility

Workflow

Step 1: Get Webhook URL

In Google Chat:

Open a Space > click space name > Manage webhooks
Create webhook (name it, optionally add avatar URL)
Copy the webhook URL

Store the URL as an environment variable or in your secrets manager — never hardcode.

Step 2: Choose Message Type

Need	Type	Complexity
Simple notification	Text message	Low
Structured info (status, digest)	Card message (cardsV2)	Medium
Ongoing updates	Threaded replies	Medium
Action buttons (open URL)	Card with buttonList	Medium
