Myaza sends a POST request to your endpoint whenever a monitored address receives a transaction.

​
Webhook Payload

{
  "id": "wh_123e4567-e89b-12d3-a456-426614174000",
  "chain": "polygon",
  "address": "0x1A2B3C4D...", // your monitored address
  "addressFrom": "0xSENDER...", // the sender
  "symbol": "USDC",
  "contractAddress": "0x2791Bca...",
  "amount": "100.0",
  "txId": "0xabcdef...",
  "blockNumber": 58234123,
  "subscriptionType": "ADDRESS_TRANSACTION",
  "swept": false,
  "status": "delivered",
  "createdAt": "2025-03-21T10:00:00.000Z"
}

​
Setting Up Your Endpoint

Your webhook endpoint must:
  1. Accept POST requests with JSON body
  2. Return 200 OK within 10 seconds — or Myaza will consider delivery failed and retry
  3. Be publicly accessible via HTTPS
// Node.js / Express example
app.post("/webhooks/myaza", express.json(), async (req, res) => {
  // Step 1: Acknowledge IMMEDIATELY
  res.status(200).json({ ok: true });

  // Step 2: Process asynchronously
  const event = req.body;
  await processTransaction(event);
});

​
Retry Policy

If your endpoint does not return 200, Myaza retries with exponential backoff:
AttemptDelay
1st retry1 minute
2nd retry5 minutes
3rd retry30 minutes
4th retry2 hours
5th retry6 hours
After 5 failed attempts, the webhook is marked failed. You can manually retrigger it from the dashboard or via the Retrigger API.

​
Idempotency

Your endpoint may receive the same webhook multiple times (retries, network issues). Always design for idempotency: 
async function processTransaction(event) {
  // Check if we've already processed this transaction
  const existing = await db.transactions.findOne({ txId: event.txId });
  if (existing) {
    console.log("Duplicate webhook, skipping:", event.txId);
    return;
  }

  // Process for the first time
  await db.transactions.create({
    txId: event.txId,
    chain: event.chain,
    address: event.address,
    amount: event.amount,
    symbol: event.symbol,
    processedAt: new Date(),
  });

  await fulfillOrder(event);
}

​
Verifying Webhooks

To confirm the request came from Myaza, check that the address in the payload matches one of your monitored addresses: 
async function processTransaction(event) {
  // Verify the address belongs to your business
  const monitored = await db.monitoredAddresses.findOne({
    address: event.address,
    chain: event.chain,
  });

  if (!monitored) {
    console.warn("Received webhook for unknown address:", event.address);
    return;
  }

  // Safe to process
}
Webhook signature verification (HMAC) is on the Myaza roadmap. Watch the Changelog for updates.

​
Testing Webhooks Locally

Use a tunnel like ngrok to expose your local server during development: 
# Start your server
node server.js  # listening on port 3000

# In another terminal, expose it publicly
ngrok http 3000
# → https://abc123.ngrok.io
Set https://abc123.ngrok.io/webhooks/myaza as your webhook URL in the dashboard, then send a test transaction.

​
Monitoring Delivery

View all webhook events and their delivery status in the dashboard, or via the API: 
# See failed webhooks
curl "https://secureapi.gridlog.io/api/v1/webhooks?status=failed" \
  -H "Authorization: Bearer YOUR_JWT"

# Retrigger a failed one
curl -X POST "https://secureapi.gridlog.io/api/v1/webhooks/wh_123.../retrigger" \
  -H "Authorization: Bearer YOUR_JWT"
