Use this page to implement webhook delivery end to end: configure endpoint, pass verification, verify signatures, and process strategy notifications.

​
What webhooks do

MemePerfect sends POST requests to your endpoint when configured events occur. You can use this to:
  • trigger your own bot or worker
  • pipe alerts into internal systems
  • react programmatically without polling

​
Endpoints to configure webhook

  • GET /webhook to read current configuration
  • PUT /webhook to enable/disable and set URL
See full auth and base URL details in APIs.

​
1) Read webhook config

curl -s "https://api.memeperfect.io/api/external/v1/webhook" \
  -H "X-API-Key: YOUR_API_KEY"
Example response: 
{
  "enabled": false,
  "hasSecret": false
}

​
2) Enable webhook and set URL

curl -s -X PUT "https://api.memeperfect.io/api/external/v1/webhook" \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "enabled": true,
    "url": "https://your-domain.com/memeperfect/webhook"
  }'
Example response: 
{
  "enabled": true,
  "url": "https://your-domain.com/memeperfect/webhook",
  "verifiedAt": "2026-03-09T10:12:11.145Z",
  "hasSecret": true,
  "secret": "RANDOM_SECRET_SHOWN_ON_GENERATION_ONLY",
  "verificationError": null
}
Save secret securely. It may only be shown when generated/rotated.

​
Verification handshake

When your URL is added or changed, MemePerfect sends:
  • event type: webhook.endpoint_verification
  • body includes data.challenge
Your endpoint must:
  1. return 2xx
  2. return JSON with the same challenge value
Example verification payload: 
{
  "id": "evt_2d21a9f2-2f41-49c4-8924-19622c76b1fa",
  "type": "webhook.endpoint_verification",
  "created_at": "2026-03-09T10:12:10.983Z",
  "data": {
    "challenge": "4f5d2a..."
  }
}
Example verification response from your endpoint: 
{
  "challenge": "4f5d2a..."
}

​
Notification event payload

When a Strategy match is dispatched, MemePerfect sends notification.dispatched. Example payload: 
{
  "id": "evt_7983e267-d8f4-4477-89c9-8d0f748f7d49",
  "type": "notification.dispatched",
  "created_at": "2026-03-09T11:20:42.571Z",
  "data": {
    "notification_id": "8bb3f32d-5f46-4b5f-8b1b-9f6d11b8f845",
    "strategy": {
      "id": "9a46ddf3-98fd-4cf5-8fd0-022421741c35",
      "name": "API Safe Launch Flow"
    },
    "trigger": {
      "event_type": "new_token_created",
      "correlation_id": "corr_abc123",
      "timestamp": "2026-03-09T11:20:41.905Z"
    },
    "token": {
      "address": "8sJj...abc",
      "name": "Example Token",
      "symbol": "EXMPL",
      "chain_id": 1399811149,
      "price_usd": 0.00042,
      "market_cap_usd": 153000,
      "liquidity_usd": 24000
    }
  }
}

​
Webhook headers and signature

Each delivery includes:
  • X-MP-Webhook-Id
  • X-MP-Event-Id
  • X-MP-Event-Type
  • X-MP-Timestamp
  • X-MP-Signature
Signature format: 
v1=<hex(hmac_sha256(secret, timestamp + "." + raw_body))>
Use the raw request body exactly as received. Do not re-serialize JSON before verification.

​
Node.js signature verification example

import crypto from "crypto";

export function verifyMpSignature(params: {
  secret: string;
  timestamp: string;
  signature: string;
  rawBody: string;
}): boolean {
  const { secret, timestamp, signature, rawBody } = params;
  if (!signature?.startsWith("v1=")) return false;

  const payload = `${timestamp}.${rawBody}`;
  const expected = `v1=${crypto
    .createHmac("sha256", secret)
    .update(payload)
    .digest("hex")}`;

  const a = Buffer.from(signature);
  const b = Buffer.from(expected);
  if (a.length !== b.length) return false;
  return crypto.timingSafeEqual(a, b);
}

​
Operational notes

  • Webhook delivery is best-effort and does not block notification processing.
  • If URL changes, verification runs again and verifiedAt resets until success.
  • Setting url to null clears URL, secret, and verification state.
