+**Status**: Ready for Review + +--- + +## Architecture + +### Components Implemented + +#### 1. **WebhookDeliveryClient** (`app/lib/webhook-delivery.ts`) +Core HTTP delivery client with exponential backoff and circuit breaker. + +**Features**: +- Exponential backoff calculation with jitter +- Circuit breaker pattern (5 failures → open for 5 minutes) +- HMAC-SHA256 signing per attempt +- 30-second timeout enforcement +- Retryable status code classification +- Idempotent delivery ID headers + +**Key Functions**: +- `attemptDelivery()`: Single delivery attempt with retry decision +- `calculateNextRetryDelay()`: Exponential backoff + jitter +- `generateWebhookSignature()`: HMAC signing with timestamp +- `verifyWebhookSignature()`: Receiver-side verification +- `isRetryableStatus()`: Status code classification + +#### 2. **WebhookDeliveryStore** (`app/lib/webhook-delivery-store.ts`) +In-memory storage for deliveries and DLQ entries (PostgreSQL-ready). + +**Capabilities**: +- Track all delivery attempts with timestamps +- Store DLQ entries with full metadata +- Query by status, endpoint, or date range +- Scheduler for pending retries +- Statistics and monitoring + +#### 3. **WebhookDeliveryWorker** (`app/lib/webhook-delivery-worker.ts`) +Orchestrates the full retry flow and DLQ management. + +**Responsibilities**: +- Initiate delivery with correlation context +- Execute exponential backoff retry loop +- Move failed deliveries to DLQ +- Provide retry status queries +- Generate DLQ statistics + +#### 4. **API Endpoints** +Two new REST endpoints for webhook observability: + +**GET /api/webhooks/deliveries** +- Query all deliveries +- Filter by status (pending, delivered, failed, dlq) +- Filter by endpoint ID +- Pagination support + +**GET /api/webhooks/dlq** +- List all DLQ entries +- Filter by date range (`since` parameter) +- Includes failure reason and last attempt details + +--- + +## Delivery Guarantees + +### Retry Logic +

`X-StreamPay-Delivery-Id` +- Customers MUST deduplicate using this ID +- The ID persists across all 10 retry attempts +- Enables idempotent processing at destination + +--- + +## Security Implementation + +### HMAC-SHA256 Signing + +Every webhook includes a signature covering: +- Timestamp (Unix seconds) +- Delivery ID (idempotent identifier) +- Full JSON payload (stringified) + +``` +signableContent = "${timestamp}.${deliveryId}.${payload}" +signature = HMAC-SHA256(secret, signableContent) +``` + +**Header Format**: +``` +X-StreamPay-Signature: t=1700000000,id=dlv_abc123,v1=hex... +``` + +During secret rotation, StreamPay can include both the active and previous +secret signatures in the same header so in-flight deliveries continue to verify: + +``` +X-StreamPay-Signature: t=1700000000,id=dlv_abc123,v1=active_hex...,v1=previous_hex... +``` + +**Per-Attempt**: Each retry has a different signature due to timestamp change +- Attempt 1: `t=1700000000,id=dlv_123,v1=abc123...` +- Attempt 2: `t=1700000062,id=dlv_123,v1=def456...` ← Different sig, same delivery ID + +### Verification Requirements + +**Customers must verify**: +1. ✅ Signature matches (constant-time comparison) +2. ✅ Timestamp freshness (within ±5 minutes of receiver time) +3. ✅ Delivery ID in header matches request +4. ✅ Nonce/event ID has not already been processed +5. ✅ Payload wasn't tampered + +Receivers should compute `HMAC-SHA256(secret, "${timestamp}.${deliveryId}.${rawBody}")` +using the exact raw JSON body received over HTTP. During rotation, accept a +signature produced by either the current endpoint secret or the immediately +previous secret, then remove the previous secret after the rotation window ends. + +--- + +## Test Coverage + +### Unit Tests (`webhook-delivery.test.ts`) +- **Exponential Backoff**: Correct calculation, max delay capping, jitter application +- **HMAC Signing**: Signature generation, verification, tampering detection +- **Status Codes**: Correct retry/no-retry decisions for all codes +- **Client Logic**: Delivery attempts, timeout handling, circuit breaker +- **Worker Logic**: Full retry chains, DLQ movement, idempotency +- **Storage**: Record creation, querying, statistics + +**Test Count**: 35+ test cases + +### Integration Tests (`webhook-delivery.integration.test.ts`) +- **Flaky Receivers**: Intermittent failures then recovery +- **Slow Responses**: Successful but slow endpoints +- **Hanging Connections**: Timeout behavior +- **Varying Status Codes**: Mix of 429, 503, 500, 200 +- **Permanent Failures**: 404 immediate DLQ +- **Idempotency**: Same delivery ID across retries +- **Circuit Breaker**: Opens after repeated failures +- **DLQ Management**: Failed
