Slack integration

Hi,
trying to get Slack notification to work, but having trouble getting the API key. Can someone point me to where I get the API key from. I have tried a webhook and used the last part of the URL but that returns an invalid key.

thanks

  1. goto https://[YOUR_TEAM].slack.com/apps/build/custom-integration
  2. goto BOTS
  3. give it a name, then press “add bot integration”
  4. API token will be presented for cut and paste
