Your prepaid Kardlane balance crossed a threshold. While suspended, new trades go straight to review instead of being handled.
Amounts are in minor units (kobo for NGN).
Sent as a signed POST to your project’s webhook URL — see the Webhooks guide to verify the signature. Delivery is at-least-once: dedupe on the X-Kardlane-Delivery header (or data.idempotencyKey).
