Webhook troubleshooting

I’m trying to send data to Librato. I’m having trouble creating the appropriate webhook on particle.

There are at least 2 issues:

  1. When i create the webhook and subscribe to it, I get the line I want, plus a line I don’t want. The unwanted line says, “name”: “hook-response/librato_ss0807/0”. How do I get rid of this unwanted second line?

    {“name”:“librato_ss0807”,“data”:"{“gauges”: [{ “name”:“Temperature”,“value”: 81.5,“source”: 2b0041000547343138333038 }, { “name”:“Humidity”,“value”: 37.5, “source”: 2b0041000547343138333038 }]} ",“ttl”:“60”,“published_at”:“2015-08-2T17:12:22.200Z”,“coreid”:“2b0041000547343138333038”}

    {“name”:“hook-response/librato_ss0807/0”,“data”:"“ok”",“ttl”:“60”,“published_at”:“2015-08-12T17:12:22.221Z”,“coreid”:“undefined”}

  2. I am trying to delete this webhook. But I get an error. How do I resolve this?

particle webhook delete 55cb7c79e5dd8dd9067b42ae
Failed to delete, server said Permission Denied
Potentially unhandled rejection [1] {“error”: “Permission denied”} (Warning: non-Error used)

Thank you in advance.
