Webhooks

When you provide a webhook_url during SpotCast creation or refresh, SeaLegs sends a POST request to that URL when processing completes or fails.

Webhook Headers

text
Content-Type: application/json
X-SeaLegs-Event: spotcast.forecast.completed
X-SeaLegs-Signature: sha256=abc123...
X-SeaLegs-Delivery-ID: whk_abc123xyz
X-SeaLegs-Timestamp: 1733045400
User-Agent: SeaLegs-Webhooks/1.0

Verifying Signatures

Every webhook includes an HMAC-SHA256 signature in the X-SeaLegs-Signature header. Your webhook secret is available in the Developer Dashboard. Always verify the signature before processing the payload.

Python:

python
import hmac
import hashlib

def verify_webhook(payload: bytes, signature: str, secret: str) -> bool:
    expected = hmac.new(secret.encode(), payload, hashlib.sha256).hexdigest()
    return hmac.compare_digest(f"sha256={expected}", signature)

JavaScript:

javascript
const crypto = require('crypto');

function verifyWebhook(payload, signature, secret) {
  const expected = crypto.createHmac('sha256', secret).update(payload).digest('hex');
  return crypto.timingSafeEqual(
    Buffer.from(`sha256=${expected}`),
    Buffer.from(signature)
  );
}

Completed Event

json
{
  "event": "spotcast.forecast.completed",
  "created_at": "2025-12-01T10:30:45Z",
  "data": {
    "spotcast_id": "spc_abc123xyz",
    "forecast_id": "fcst_xyz789",

    "metadata": {
      "trip_name": "Weekend Fishing Trip"
    }
  }
}

The summary field is included when AI analysis completes successfully. The metadata object is included when you provided metadata in the original POST /v3/spotcast request, echoed back exactly as sent.

Failed Event

json
{
  "event": "spotcast.forecast.failed",
  "created_at": "2025-12-01T10:31:00Z",

Retry Policy

Failed deliveries are retried up to 4 times: after 5 minutes, 30 minutes, 2 hours, and 24 hours.


Understanding Results

Daily Classifications

Each forecast day receives a safety classification:

ClassificationMeaning
GOSafe conditions for the vessel type
CAUTIONProceed with awareness; conditions may be challenging
NO-GOConditions not recommended for the vessel type
Classifications are adjusted based on vessel type and size when vessel_info is provided.

Weather Variables Analyzed

  • Wind: Speed (kts), gusts, direction (degrees)
  • Waves: Height (ft), period (seconds), direction, swell
  • Visibility: Distance (nm), fog probability
  • Precipitation: Probability (%), intensity
  • Temperature: Air and water (F/C)

Vessel-Specific Adjustments

When vessel_info is provided:

  • PWC/Jet Ski: Stricter wave height limits
  • Sailboats: Wind optimization recommendations
  • Large Yachts: Higher tolerance for wave conditions
  • Small Powerboats: Balanced wind/wave thresholds
