accountSubscribe

  // Subscribe to account changes

FAQs

When should I use WebSockets vs. gRPC?

Choose LaserStream WebSocket when latency, continuity, and correctness don't affect PnL, fills, or risk; you want JSON payloads; or you're building consumer UX without backend complexity. Choose LaserStream gRPC when latency, continuity, and correctness do affect PnL, fills, or risk; you need advanced filtering; you need gapless delivery with automatic replay; or you need transactions at multiple commitment levels.

What Enhanced WSS data add-on plans are available, and how much do they cost?

Data add-on plans for Enhanced WebSockets include: 5TB ($400/mon), 10TB ($750/mon), 25TB ($1,750/mon), 50TB ($3,250/mon), and 100TB ($6,000/mon). For larger data add-ons and volume-based pricing, please contact sales.

When are webhooks automatically disabled?

Webhooks with a failure rate of 95% or higher are automatically disabled to protect your system and eliminate wasted delivery attempts. Free plan webhooks are evaluated over a 24-hour window, while paid plan webhooks are evaluated over a 7-day window. Customers on the Developer plan and above will receive an email notification whenever a webhook is automatically disabled, so you can take action quickly.

How do I re-enable a disabled webhook?

Log in to your Helius dashboard, navigate to the Webhooks section, and toggle your webhook back on. After re-enabling, your webhook has a 24-hour grace period before it is evaluated again, so you have time to fix the underlying issue. You can also use the Toggle Webhook endpoint to programmatically re-enable a disabled webhook.
