Yahoo! Groups is Yahoo's combination mailing list service/web forum; it's the result of the acquisition of eGroups and some other Yahoo! stuff. In addition to archives of and a web interface for mailing lists, it offers file uploads, photo uploads, links, polls, and an events calendar.

Uploading of new content will be disabled 28 October 2019, and all content, including message history, will be deleted 14 December 2019.[1] (The mailing lists themselves will continue to function.)

Public groups can be nominated for archival using this form.

It's been stable for a long time (since the late 90s), long enough for some specialised software to be developed to do backups of it. (Not many other websites can say that.)

Statistics

As of 2019-10-16 the directory lists 5619351 groups. 2752112 of them have been discovered. 1483853 (54%) have public message archives with an estimated number of 2.1 billion messages (1389 messages per group on average so far). 1.8 billion messages (86%) have been archived as of 2018-10-28.

Site structure

There’s a convenient JSON API. Some endpoints require logged-in group membership or other permissions (depending on group settings).

Groups

- Known params: maxHits, offset, query, sortBy (one of OLDEST, RELEVANCE, MEMBERS, LATEST_ACTIVITY, NEWEST).
- Known params: start (result index, not group id).
- Pagination: Limited to 10. Does not have a count param. May be limited to 500 total results regardless of start param.
Groups in subcategories can be listed by swapping '0' for the subcategory id (the full idList is not required). There is a /1/ with a small number of groups.

Messages

- Known params: count, start (message id, not result index).
- Pagination: Limited to 10 by default. No known limit on count or total results.
Some messages may have encoding issues.[2] Sometimes (as in the linked case) the non-raw endpoint has the correct characters, sometimes it does not; this is likely related to the originating email client.

Topics

- Known params: count.

Attachments

- Known params: count, start.
- Pagination: Limited to 30 by default.

Files

What do we know about folders and folder contents (for files, photos, links, and possibly attachments)?

Photos

Links

Polls

- Known params: count.

Databases

Members

- Known params: count, start, sortBy, sortOrder, ts, tz, chrome.
- Pagination: Limited to 10 by default or a count of 100. No known limit on total results.
May be blocked for normal members (as may all the other members endpoints). Includes moderators and bouncing members, with identifying metadata.
Very often (always?) blocked for normal members.
Very often (always?) blocked for normal members.

Events

Overlaps with Yahoo Calendar API, check nsapa's branch for the code.

Python Yahoo! Group archivers

  • yahoo-group-archiver scrapes a group using the JSON API and (for private endpoints) the two cookies Yahoo uses to verify a logged-in user. Relevant forks include Frankkkkk and nsapa. Needs merging. Various branches have support (largely untested) for file attachments, photos, links, folders, and events.
  • YahooGroups-Archiver is similar, but scrapes only messages (not files or any other data). It is not currently under active development.
  • yahoo-groups-backup scrapes a group using Selenium, storing message info and metadata (both rendered message body and raw email) into a Mongo database. It also provides a script to dump its data to static HTML pages that can be viewed in the browser.

Other archivers

  • Yahoo Group Archiver: Perl, defunct.
  • PGOffline: Windows, proprietary. 14-day free trial, after which download and export is disabled (but view still works). Includes attachments. Stores data in a SQLite database internally.
  • Yahoo Messages Export: Chrome extension. Messages only. Saves as mbox.
