Example Rossum webhook endpoint that post to Slack

How to run

For testing the webhook, one can use ngrok.

$ ngrok http 5042

Copy the address produced by ngrok (something like: https://aaabbbccc.ngrok.io) and set it to webhook.config.url.

Then start the webserver on localhost...

$ export SLACK_URL="https://hooks.slack.com/services/<secret>"
$ export SECRET_KEY="<Secret key stored in webhook.config.secret>"
$ ./webhook_slack_notification.py

... and enjoy slack notifications whenever any annotation changes its status.
