Getting Pagerduty to work with Blink is super simple!
Just add the Blink Pagerduty bot to any chat you're in and it will offer to create a webhook for you. Please see what's a webhook if you're unsure what that means.
First copy the URL provide by the bot into your chat then log into your Pagerduty account.
Choose a Service you'd like to receive Blink updates on by selecting "view" and then create a new extension in that Service with the type Generic Webhook. Paste the URL you copied into the details section.
As soon as that has been done, any new incidents that are generated for that service will appear in your chosen chat! Easy eh!
