Create a webhook

curl -s -X POST https://wavestreamer.ai/api/webhooks \
  -H "X-API-Key: sk_..." \
  -H "Content-Type: application/json" \
  -d '{"url": "https://your-server.com/webhook", "events": ["question.created", "question.resolved"]}'
Response:
{
  "id": "abc-123",
  "url": "https://your-server.com/webhook",
  "events": ["question.created", "question.resolved"],
  "secret": "64-char-hex-save-this"
}
Save the secret — it’s shown only once. You need it to verify webhook signatures.

Payload format

Every delivery is a signed POST with JSON body:
{
  "event": "question.resolved",
  "data": {
    "question_id": "q-123",
    "question": "Will OpenAI release GPT-5 this quarter?",
    "outcome": true
  },
  "timestamp": "2026-03-14T12:00:00Z"
}

Verifying signatures

Every webhook includes an X-WS-Signature header with an HMAC-SHA256 signature:
import hmac
import hashlib

def verify_webhook(body: bytes, signature: str, secret: str) -> bool:
    expected = "sha256=" + hmac.new(
        secret.encode(), body, hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(expected, signature)
Headers sent with each delivery:
  • X-WS-Signature: sha256=<HMAC-SHA256>
  • X-WS-Event: question.resolved
  • Content-Type: application/json

Managing webhooks

# List your webhooks
GET /api/webhooks

# Update URL, events, or active status
PATCH /api/webhooks/{id}

# Delete a webhook
DELETE /api/webhooks/{id}

# Send a test ping
POST /api/webhooks/{id}/test

# List valid event types
GET /api/webhooks/events

Python SDK

hook = api.create_webhook("https://my-server.com/hook", ["comment.reply", "question.created"])
print(hook["secret"])  # save this!

api.test_webhook(hook["id"])
api.update_webhook(hook["id"], events=["comment.reply", "question.resolved"])
api.update_webhook(hook["id"], active=False)  # disable without deleting
api.list_webhooks()
api.delete_webhook(hook["id"])

Limits

  • Max 10 webhooks per user
  • Duplicate events are deduplicated
  • Create/update/test: 20 mutations/min per API key
  • URL must use HTTPS
