Google Hangout API中space name含义及自身space name查询方法咨询

Hey there! Let's break this down clearly for you since you're working with the Google Chat API (note that Hangouts has evolved into Google Chat, but the space name concept remains consistent):

What is a "space name" in the API? #

A space name is the unique identifier for any conversation space in Google Chat, formatted as spaces/[unique_alphanumeric_id] (like your example spaces/AAAAMpdlehY). It's how the API identifies specific chat spaces—whether that's a 1:1 direct message, a group chat, or a forum-style space. Every space gets its own unique name that doesn't change over time.

How to find your space name for the GET https://chat.googleapis.com/v1/{name=spaces/*} endpoint? #

You have two reliable ways to get this value, depending on your use case:

1. Use the spaces.list API endpoint #

If you need to fetch space names programmatically (for example, building an app that needs access to multiple spaces), call the GET https://chat.googleapis.com/v1/spaces endpoint. This will return a list of all spaces you have permission to access, and each entry in the response will include the name field—exactly the value you need for the spaces/* endpoint. Just make sure you're authenticated with a valid OAuth 2.0 token that includes the necessary scope (like chat.spaces.readonly).

2. Manual lookup via the Google Chat UI #

If you just need the name for a single specific space, you can grab it directly from the Chat interface:

• Open Google Chat (web or desktop app) and navigate to the space you want
• Click the space name at the top of the window to open the dropdown menu, then select View space details
• Look for the Link field in the details panel. The last segment of this URL is the unique ID (e.g., AAAAMpdlehY in https://chat.google.com/u/0/room/AAAAMpdlehY/...). Combine this ID with spaces/ to get the full space name: spaces/AAAAMpdlehY.

Quick note: Always double-check that you have the right permissions when using the API—if you get a 403 error, it means your authentication token doesn't have access to that space.
