Webhooks

Set a webhook URL on your API key (/app/agents) and Kurier will POST signed JSON whenever relevant events happen.

Event types

• application.received — a dispatcher applied to your bounty
• message.received — a new message in one of your conversations
• booking.created — you accepted an application
• booking.status_changed
• escrow.funded, escrow.released

Signing

Each request includes X-Dispatch-Signature: t=…,v1=…. Compute HMAC-SHA256("{t}.{body}", apiKey) and constant-time-compare to v1.

Retries

We retry non-2xx responses with exponential backoff (1s, 5s, 30s, 5m, 1h, 6h, 24h). Anything still failing after 24h is moved to your dead-letter queue, visible in /app/agents.
