# Solana Webhooks: Real-Time Blockchain Event Notifications

> Monitor Solana blockchain events with real-time webhooks. Get instant notifications for NFT sales, token transfers, and transactions sent to your endpoints.

## What are Solana webhooks?

Solana webhooks are real-time HTTP notifications sent to your application when on-chain events occur. Instead of continuously polling the blockchain, Helius pushes parsed transaction data directly to your endpoint whenever a wallet transfers funds, an NFT sells, or any monitored transaction type fires. Use webhooks to power trading bots, analytics dashboards, compliance pipelines, and event-driven automation.

We offer a user-friendly interface, programmatic API, and SDK access for easily creating and managing webhooks. For frequently asked questions, see the [Webhooks FAQ](/faqs/webhooks).

<Warning>
  Helius may retry webhook deliveries if your server does not respond successfully, and you might receive duplicate events. For details on retries and handling duplicates, see the [Webhooks FAQ](/faqs/webhooks#retries).
</Warning>

## Pricing

Webhook events are charged at **1 credit** when Helius processes and sends the event to your endpoint. You are charged regardless of whether your endpoint successfully processes the webhook or not. Editing, adding, or deleting a webhook via the API will cost 100 credits/request.

## Types of Webhooks

We currently offer several types of webhooks tailored to different needs:

### Enhanced Transaction Webhooks

Provide human-readable, parsed data for specific transaction types (e.g., NFT sales) related to the addresses you monitor. This is ideal if you want filtered, actionable insights.

### Raw Transaction Webhooks

This option delivers raw transaction data for all transactions involving the addresses you monitor. It does not allow filtering by transaction type.

<Info>
  Raw Transaction Webhooks offer lower latency since they do not involve parsing event types.
</Info>

### Discord Webhooks

Stream updates for specific transaction types directly to a designated Discord channel as formatted messages. To use this option, you must submit your Discord Webhook URL.

## Get Started

<Card title="Webhooks Quickstart" icon="bolt" href="/webhooks/quickstart">
  Create your first webhook via the Dashboard, REST API, or official TypeScript / Rust SDK.
</Card>

## Automatic Disabling of Failing Webhooks

Helius monitors webhook endpoint health and automatically disables webhooks that consistently fail to receive deliveries. This prevents wasted delivery attempts against unreachable or broken endpoints.

### How It Works

* **Paid plans (Dev and above):** Webhooks with a **≥ 95% failure rate over 7 days** are automatically disabled.
* **Free plan:** Webhooks are evaluated over a **24-hour window** with the same failure threshold.

The system checks webhook health every 4 hours. When a webhook is disabled, deliveries stop within seconds.

### Email Notifications

Users on the **Dev plan and above** receive an email notification when a webhook is automatically disabled.

### Re-enabling a Disabled Webhook

<Steps>
  <Step title="Fix your endpoint">
    Resolve the issue causing delivery failures (e.g., server downtime, incorrect URL, endpoint errors).
  </Step>

  <Step title="Log in to the Helius Dashboard">
    Go to the [Helius Dashboard](https://dashboard.helius.dev/webhooks).
  </Step>

  <Step title="Re-enable the webhook">
    Find the disabled webhook and toggle it back on.
  </Step>
</Steps>

You can also re-enable webhooks programmatically via the [Toggle Webhook API endpoint](/api-reference/webhooks/toggle-webhook).

<Note>
  After re-enabling, the webhook enters a **24-hour grace period** during which it will not be automatically disabled again. This gives you time to verify that your endpoint is healthy.
</Note>

## Example Uses

### Bots

* When an NFT is listed on marketplace X, trigger an "NFT buy" action.
* When a margin position is unhealthy, trigger a "liquidation" action.

### Monitoring & Alerts

* When a program emits a certain log, it triggers PagerDuty integration.
* When a token account balance changes by more than X%, use Dialect to communicate a warning action.

### Event-driven Indexing

* When any transaction occurs for a given program, send it directly to your database or backend.

### Notifications & Activity Tracking

* When transferring from wallet X to wallet Y — send a Slack notification or email.

### Analytics & Logs

* When event X happens, send it to an ETL pipeline or persist it directly on Helius to view trends over time.

### Workflow Automation

* When event X happens, trigger any set of actions.
