Description of the feature request
The outgoing webhook is awesome, but if we need to send payload data, it’s impossible.
Use case / for what or how I would use it
For example, we have the Rocket Chat API, that’s similar to Slack API. We want to send the an custom Outgoing Webhook, with some custom message, profile and other data.
We know that we can send it in bash script, however it’d be nice if we can send without create one more step to do this.
