はじめに

参考

api.slack.com

前提

SlackのAPIを実行するためには、トークンが必要になるため、トークンを定義した上で実行します。

slack_api_token="xoxb-xxxxxxxx-xxxxxxxxxxx-xxxxxxxxxxxxx"

また、ほとんどのコマンドにlimit=1を付与しているため、出力結果が1個になります。

GET系

メッセージの取得(conversations.history)

事前定義

channel_id="[チャンネルID]"

コマンド

curl -s "https://slack.com/api/conversations.history?channel=${channel_id}&limit=1" \
    -H "Authorization: Bearer ${slack_api_token}" \
    -H 'Content-Type: application/json; charset=utf-8' \
    | jq
