This operator allows you to post messages to Slack using Incoming Webhooks.

Note

You cannot override the default channel (chosen by the user who installed your app), username, or icon when you’re using Incoming Webhooks to post messages. Instead, these values will always inherit from the associated Slack App configuration (link). It is possible to change this values only in Legacy Slack Integration Incoming Webhook.

  • blocks (list | None) – The blocks to send on Slack. Should be a list of dictionaries representing Slack blocks.
