Built for platforms

One API for your entire customer base.

Lossline handles incident processing once. Your platform decides who receives it.

01 / Routing

Your customer IDs. Our routing.

Send an opaque ID and its territory list. Every finished incident returns all matching IDs in one delivery.

  • One webhook, even when dozens of customers match
  • No end-customer names, emails, or phone numbers required
  • Customer-scoped history for onboarding and support
  • Your platform controls push, email, SMS, and in-app delivery
02 / Processing

No joins. No duplicate billing.

Enrichment is automatic. Each unique incident becomes one immutable record and one charge for your organization.
