This Processor makes use of a Webhook URL, rather than Slack's REST API. As a result, the Processor is more difficult to configure than necessary and requires special permissions for the Slack Application / Bot. These permissions must be granted for every channel that the application is to respond to, which makes setup and maintenance difficult. Additionally, it does not make clear the differences between PutSlack and PostSlack. Each provides slightly different capabilities. PublishSlack combines the capabilities of both Processors in a simpler configuration that makes use of Slack's standard REST API.
Please consider using one the following alternatives: PublishSlack
