Helius Webhooks enable seamless monitoring of Solana on-chain events, such as sales, listings, swaps, and more. We offer a user-friendly interface, programmatic API, and SDK access for easily creating and managing webhooks.
For a detailed list of supported events, please refer to our documentation.
Webhook events are charged at 1 credit. 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.
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.
Raw Transaction Webhooks offer lower latency since they do not involve parsing event types.
We provide three convenient methods to create, edit, and manage webhooks on Helius.
Via Helius Dashboard
The Helius UI is perfect if you prefer a no-code solution with additional features like viewing logs and sending test webhook events. You can access it directly through our Dashboard. You can add up to 25 addresses via the Dashboard. To monitor more than 25 addresses, you can use our API or SDK.
Via Helius API
If you're not working with Typescript or Javascript, you'll need to interact with our webhooks through REST API:
Via Helius SDK
The easiestβand most enjoyableβway to interact with Helius webhooks is through our official SDKs. We currently offer SDKs for TypeScript and Rust.
The SDKs provide powerful abstractions that enhance the functionality of webhooks, including the ability to create collection webhooks that effortlessly track all NFTs within a specific NFT collection!
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 β 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.
