Introduction

These features were added in version 6.60.00.

To use these commands you must update your service account authorization.

gam user user@domain.com update serviceaccount

[*]  3)  Chat API - Memberships (supports readonly)
[*]  4)  Chat API - Messages (supports readonly)
[*]  5)  Chat API - Spaces (supports readonly)
[*]  6)  Chat API - Spaces Delete

Google requires that you have a Chat Bot configured in order to use the Chat API; set up a Chat Bot as described in the next section.

Set up a Chat Bot

• Run the command gam setup chat; it will point you to a URL to configure your Chat Bot; this is required to use the Chat API.
• Enter an App name and Description of your choosing.
• For the Avatar URL you can use https://dummyimage.com/384x256/4d4d4d/0011ff.png&text=+GAM or a public URL to an image of your own choosing.
• In Functionality, uncheck both "Receive 1:1 messages" and "Join spaces and group conversations"
• In Connection settings, choose "Cloud Pub/Sub" and enter "no-topic" for the topic name. GAM doesn't yet listen to pub/sub so this option is not used.
• In Visibility, uncheck "Make this Chat app available to specific people and groups in Redwood Day School".
• Click Save.

Manage Chat Spaces

Create a chat space

gam <UserTypeEntity> create chatspace
        [type <ChatSpaceType>]

For type space, the following apply:

• member <UserTypeEntity> - Optional, can not specify more that 20 users
• displayname <String> - Required
• description <String> - Optional
• guidelines <String> - Optional
• history <Boolean> - Optional

For type groupchat, the following apply:

• member <UserTypeEntity> - Required, must specify between 2 and 20 users

Use the <ChatContent> option to send an initial message to the created chatspace.

By default, details about the chatmessage are displayed.

Update a chat space

gam <UserTypeEntity> update chatspace <ChatSpace>
        [type space]
        [displayname <String>]
        [description <String>] [guidelines <String>]
        [history <Boolean>]
        [formatjson]

A groupchat space can be upgraded to a space by specifying type space and displayname <String>.

By default, Gam displays the information about the created chatspace as an indented list of keys and values.

• formatjson - Display the fields in JSON format.

Delete a chat space

gam <UserTypeEntity> delete chatspace <ChatSpace>

Display Chat Spaces

Display information about a specific chat space for a user

gam <UserTypeEntity> info chatspace <ChatSpace>
        [formatjson]

By default, Gam displays the information as an indented list of keys and values.

Display information about all chat spaces for a user

gam <UserTypeEntity> show chatspaces
        [types <ChatSpaceTypeList>]
        [formatjson]

• formatjson - Display the fields in JSON format.

By default, when writing CSV files, Gam uses a quote character of double quote ". The quote character is used to enclose columns that contain the quote character itself, the column delimiter (comma by default) and new-line characters. Any quote characters within the column are doubled. When using the formatjson option, double quotes are used extensively in the data resulting in hard to read/process output. The quotechar <Character> option allows you to choose an alternate quote character, single quote for instance, that makes for readable/processable output. quotechar defaults to gam.cfg/csv_output_quote_char. When uploading CSV files to Google, double quote " should be used.

Display information about all chat spaces for a collection of users

gam config auto_batch_min 1 redirect csv ./ChatSpaces.csv multiprocess [todrive <ToDriveAttribute>*] redirect stdout - multiprocess redirect stderr <UserTypeEntity> print chatspaces

Manage Chat Messages

Create a chat message in a space

Messages are limited to 4,096 characters and will be trimmed to that length.

Chat supports simple formatting allowing you to bold, underline, italics and strikethrough your text.

gam <UserTypeEntity> create chatmessage <ChatSpace>
        <ChatContent>
        [messageId <ChatMessageID>]
        [(thread <ChatThread>)|(threadkey <String>) [replyoption fail|fallbacktonew]]
        [returnidonly]

Specify the text of the message: <ChatContent>

• text <String> - The message is <String>
• textfile <FileName> [charset <CharSet>] - The message is read from a local file
• gdoc <UserGoogleDoc> - The message is read from a Google Doc.
• gcsdoc <StorageBucketObjectName> - The message is read from a Google Cloud Storage file.

By default, a new message thread is created; use thread <ChatThread> or threadkey <String> to create the message as a reply to an existing thread. Use replyoption to specify what happens if the specified thread does not exist:

• fail - If the thread soes not exiat, a Not Found error is generated
• fallbacktonew - If the thread does not exist, start a new thread

The first time you reply to a thread you must use thread <ChatThread>; if you also specify threadkey <String> then you can use just threadkey <String> in subsequent replies.

If you specify thread or threadkey but not replyoption, the default is `fail'.

By default, details about the chatmessage are displayed.

• returnidonly - Display the chatmessage name only

Examples

This example creates a new chat message in the given room.

gam user user@domain.com create chatmessage space spaces/iEMj8AAAAAE text "Hello Chat"

gam user user@domain.com create chatmessage space spaces/AAAADi-pvqc thread spaces/AAAADi-pvqc/threads/FMNw-iE9jN4 text "*Bold* _Italics_ ~Strikethrough~"

This example reads the MotD.txt file and posts its contents to Chat.

gam user user@domain.com create chatmessage spaces spaces/AAAADi-pvqc textfile MotD.txt

This example reads the Google Doc MotD and posts its contents to Chat.

gam user user@domain.com create chatmessage spaces spaces/AAAADi-pvqc gdoc announcements@domain.com name "MotD"

Update a Chat Message

        <ChatContent>

Specify the text of the message: <ChatContent>

• text <String> - The message is <String>

        [formatjson]

By default, Gam displays the information as an indented list of keys and values.

• formatjson - Display the fields in JSON format.

gam <UserTypeEntity> print chatmessages [todrive <ToDriveAttribute>*] <ChatSpace>
        [showdeleted [<Boolean>]] [filter <String>]

By default, Gam displays the information as columns of fields; the following option causes the output to be in JSON format,

By default, when writing CSV files, Gam uses a quote character of double quote ". The quote character is used to enclose columns that contain the quote character itself, the column delimiter (comma by default) and new-line characters. Any quote characters within the column are doubled. When using the formatjson option, double quotes are used extensively in the data resulting in hard to read/process output.

When uploading CSV files to Google, double quote " should be used.

By default, deleted messages are not displayed; use showdeleted to also display deleted messages.

Use filter <String> to filter messages by createTime' and thread.name`.

To filter messages by the date they were created, specify the createTime with a timestamp in RFC-3339 format and double quotation marks. For example, "2023-04-21T11:30:00-04:00".

• Use the greater than operator > to list messages that were created after a timestamp.
• Use the less than operator < to list messages that were created before a timestamp.
• To filter messages within a time interval, use the AND operator between two timestamps.
• To filter by thread, specify the thread.name, formatted as spaces/{space}/threads/{thread}. You can only specify one thread.name per query.
• To filter by both thread and date, use the AND operator in your query.

For example, the following queries are valid:

createTime > "2012-04-21T11:30:00-04:00"
createTime > "2012-04-21T11:30:00-04:00" AND thread.name = spaces/AAAAAAAAAAA/threads/123
createTime > "2012-04-21T11:30:00+00:00" AND createTime < "2013-01-01T00:00:00+00:00" AND thread.name = spaces/AAAAAAAAAAA/threads/123
thread.name = spaces/AAAAAAAAAAA/threads/123
