Zoom Archive Tool

Copies Zoom recordings to Google Drive.

Why

• Improve discoverability of Zoom recordings
• Preserve recordings when Zoom user leaves the org
• Reduce cost of long term retention (maybe)

How

zat requires go to build - 1.13+ is recommended, for proper error formatting, but will work with older versions.

$ go build .
$ ./zat

zat should start without any configuration but isn't very useful without credentials - see below for setup.

zat will persist tokens to disk at google.creds.json and zat.creds.json - be sure to guard those files carefully as permissions are necessarily wide.

Once tokens have been obtained, zat -no-server will perform only archival duties and then exit.

zat always attempts to archive, to only start the web server use: -since 0s.

Credentials

• Obtain Google credentials

  • Create an Oauth Client ID credential
    • You may need to create a project, or use a dev project you have access to. If the project doesn't have OAuth consent screen info, you'll need to add that as well.
      • Choose "internal" user type, give it a name similar to the project name, and add your contact email
    • Choose "Web application" as the client ID type
    • Set Authorized redirect URIs to http://localhost:8080/oauth/google
  • Save credentials to google.config.json (GCP Console > API & Services > Credentials > Download JSON)

• Obtain Zoom credentials

  • Create an Oauth Application
    • User-managed
    • No need to publish
    • Set name, descriptions, and contact information
    • Add the recording:read scope
    • Set redirect URI to http://127.0.0.1.ip.es.io:8080/oauth/zoom and also add it to Whitelisted URLs
  • Save credentials to zoom.config.json with content:

    {
      "id":             "your-id",
      "secret":         "your-secret",
      "oauth_redirect": "http://127.0.0.1.ip.es.io:8080/oauth/zoom"
    }
    

• [Optional] Obtain Slack credentials

  • Create an App
    • Add Permissions > Scopes > Bot Token Scopes > Add An Oauth Scope granting: channels:read, chat:write, chat:write.public
  • Save the Bot User OAuth Access Token (under OAuth & Permissions) to slack.config.json with content:

    {
      "token":             "your-token"
    }
    

Once the credentials are in place, re-run zat and use the web server at http://localhost:8080/ to login to both Google and Zoom to create the *.creds.json files zat will use for the next run.

Configuration

• Configure zat

Create zat.yml like:

- name: UI Weekly
  google: DpB3XhhzV87LfEeLrM-nCopTtHDWxqVGH
  zoom: 023-456-789
- name: Team Weekly
  google: DpB3XhhzV87LfEeLrM-nCopTtHDWxqVGH
  zoom: 123-456-789

Where google is the folder ID to store recordings into, and zoom is the meeting id (hyphens or no hyphens, not spaces).

Google

The google configuration is the ID of the folder where the recordings will be stored.

cmd/google/findfolders can assist in tracking down folders and IDs like:

$ go build ./cmd/google/findfolders
$ ./findfolders -query 'name = "bar"'
foo                                                          DpB3XhhzV87LfEeLrM-nCopTtHDWxqVGH https://drive.google.com/drive/folders/DpB3XhhzV87LfEeLrM-nCopTtHDWxqVGH
$ ./findfolders -query '"DpB3XhhzV87LfEeLrM-nCopTtHDWxqVGH" in parents and name = "Meetings"'
Meetings                                                     ycMAKmDuzwobv6eBf9-PLupEGJJ6BtyoJ https://drive.google.com/drive/folders/ycMAKmDuzwobv6eBf9-PLupEGJJ6BtyoJ

You'll likely get an "Access Not Configured" error for new projects. Follow the URL in the error to ensure the project is enabled for Google Drive API access, then wait a few minutes before retrying.

zat provides a web interface with similar functionality, eg http://localhost:8080/google?q=name contains "Team weekly".

Zoom

The zoom configuration is the meeting ID - the dashes are optional.

cmd/zoom/listrecordings can assist in tracking down meeting IDs like:

$ go build ./cmd/zoom/listrecordings
$ ./listrecordings -since 96h
2019/11/25 12:22:54 listrecordings.go:41: 2 recordings found
2019-11-21 945106202 UI Weekly

	timeline https://zoom.us/recording/download/22222222-2222-2222-2222-222222222222

zat provides a web interface with similar functionality at http://localhost:8080/zoom.

Slack

The slack configuration is the ID of the channel where the message should be sent.

cmd/slack/listchannels can assist in tracking down channel IDs like:

$ go build ./cmd/slack/listchannels
$ ./listchannels
CAAAAAAAA general
CAAAAAAAB zat

One method for finding private channel IDs is to open Slack in a web browser and look at `$$('.p-channel_sidebar__static_list__item')` elements.
The application's bot user will need to be invited to the private channel to post messages there.

cmd/slack/chat can assist in verifying permissions are correct.

Scheduling

On macOS pre-10.15 (Catalina) and Linux, cron is sufficient, eg:

0 8,10,15,22 * * * zat -no-server -config-dir ~/path/to/zat/config/dir

On macOS 10.15+, new security restrictions make cron less attractive.

Instead use launchd. A sample configuration is included under contrib/. Load it with:

launchctl load contrib/zat.plist

If prompted the first time the job runs, grant zat access to the config directory.
