Test working. Will not allow create with only Webhook URL

[ben-rainville]

I've setup and configured Slack integration using a webhook URL. I am getting successful test messages in the channel when I click "Execute Test Notification". When I try to click the "Create" button I get the message "Please fill out this field." for the Slack Token. I do not need a slack token. I do not plan on using any buttons. We have also restricted our graylog website to VPN access only so there is no public api available for slack to make a call back. I just want to be able to save the configuration without a slack token and have it use the webhook URI that can successfully write the test messages.

I tried null values, and spaces in the slack token. I also tried setting up a slack token for the integration. All values in the slack token break the test as my graylog api is not publicly available.

Me too, unable to use slack notifications just for this issue :-(
