Designs event-driven architectures, webhook systems, API chaining flows, ETL pipelines, and integration patterns between services.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## Webhook Design
### Outbound Webhook Endpoint (from your system to 3rd party)
```
POST {subscriber_url}
Headers:
Content-Type: application/json
X-Webhook-Signature: hmac-sha256=<sig>
X-Webhook-Event: order.created
X-Webhook-Delivery: <uuid>
X-Webhook-Timestamp: <unix-epoch>
```
**Payload envelope**
```json
{
"event": "order.created",
"delivery_id": "uuid",
"created_at": "ISO8601",
"data": { ... }
}
```
**Signature verification** (receiver side):
```python
import hmac, hashlib
expected = hmac.new(secret.encode(), payload_bytes, hashlib.sha256).hexdigest()
assert f"sha256={expected}" == request.headers["X-Webhook-Signature"]
```

How to install
mdr add francostino/opencode-skills-collection/api-integration@sha256:6e50f28c1866d763The line at the top of this page pins the label git:20260906.7d37dc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
