Webhooks

In addition to our 1Stream API which allows you to manually trigger the on-call system with something like a PowerShell script in an RMM, you can also leverage Webhooks to send in alerts from many online providers that support it.

In order to utilize this feature, you must first have Voicemail Monitoring Signal Setup configured to send text, phone call, and/or email alerts to a selection of users. You don't need to have the voicemail box used for anything, but it should be configured to ensure proper functionality and monitoring.

Generic Webhook

  1. Login to the 1Stream portal for your region
  2. Open the Signal schedule you want to send a notification to
  3. Copy the Webhook ID value
  4. Configure your system to use the following webhook URL:
    [your regional portal address]/SignalWebHook.ashx?hookId=[webhook ID]&type=generic
  5. Configure the body to be the following:
    { “message” : “[Your text here. Include ”Respond Yes to acknowledge" if you desire]" }
  6. Test the alert and you should receive that message played via text to speech on a call, or sent via text message.
