How LPR webhook payloads include event image URLs

LPR alert webhooks now include pre-signed URLs for the plate image and overview image — valid for 72 hours, no S3 credentials required.

Overview
When a Corvid LPR alert fires via webhook, the payload now includes pre-signed URLs for the plate image and overview image associated with the event. These links allow external systems to access event images directly without requiring AWS S3 credentials.

What Changed

  • LPR webhook payloads now include plateImage and overviewImage as pre-signed HTTPS URLs.

  • Each URL is valid for 72 hours from the time the webhook fires.

  • If an image is unavailable at the time of the webhook, the corresponding field is omitted from the payload.

Notes for Integrators

  • These URLs are temporary and expire after 72 hours. Download and store images promptly if long-term retention is needed.

  • No additional authentication is required to access the pre-signed URLs — the URL itself contains the credentials.

  • This change is backwards-compatible. Existing webhook receivers that ignore unknown fields are unaffected.

  • To set up or manage webhooks, go to Organization Settings → Webhooks.
