Description

Since CONNECTORS-1119 ManifoldCF has the ability to send notifications on certain job statuses. Notification endpoints are realized by INotificationConnector implementors.

It would be awesome to have a notification connector for Slack channel.

Slack has a HTTP API (https://api.slack.com/web) and there are a lot of java examples showing how to pull this off: https://api.slack.com/community#java
The simplest way for an integration are Slack incoming webhooks

Sample Request

POST https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX
Content-type: application/json
{
    "text": "This is a line of text.\nAnd this is another one."
}

We plan to contribute this connector on November 24th 2016 in the context of a Open Source Hackathon at DB Systel GmbH
