Escalate critical Disruptive Technologies cold-chain temperature excursions to on-call responders via the PagerDuty Events API v2

Steps

1. Set up a DT Studio Data Connector webhook for temperature events, pointing at your own receiver, as with the Slack integration
2. In your receiver, verify the X-Dt-Signature JWT and evaluate the reading against your excursion threshold
3. On a critical excursion, POST to https://events.pagerduty.com/v2/enqueue with routing_key (your PagerDuty integration key), event_action=trigger, and payload.summary/payload.severity/payload.source
4. Use a stable dedup_key (e.g., the DT device ID) so repeated excursion events update the same incident instead of creating duplicates
5. Send event_action=resolve with the same dedup_key once the temperature returns to range
