We currently have a Slack channel with ~8K messages all comes from Jenkins integration. Is there any programmatic way to delete all messages from that channel? The web interface
Here is a great chrome extension to bulk delete your slack channel/group/im messages - https://slackext.com/deleter , where you can filter the messages by star, time range, or users.
BTW, it also supports load all messages in recent version, then you can load your ~8k messages as you need.
