Message Slack channel (row based)

Slack Integration - Node extension for KNIME Workbench version 2.9.2.v202009291456 by Samuel Webb

Send messages to slack. This node is capable of sending multiple messages to multiple channels. Specify the channel name and the message in the dialog.

API call details: https://api.slack.com/methods/chat.postMessage

Notes on username: By default the message will be sent and display with the apps name. If the chat:write:customize scope has been added then it is possible to set a username parameter. If changing the display name / username of the source of the message is desirable then check 'Set username' and provide the username to post the message as.

Rate Limiting: The underlying Java Slack API offers an async approach where it attempts to manage Rate Limits on API requests. This node node uses the aysnc version of the method and will send approximately 1 message per second.
