Developer Portal
Helio Developer Portal

Build on Helio.

REST and WebSocket APIs for brokers, trading terminals, and the systems that connect them. Pick the path that matches what you’re shipping — the docs stay out of your way.

01Admin APIs

Backoffice & CRM

Wire your back office to Helio.

Provision clients, open accounts, move money, and keep your CRM in lockstep with the platform. This is the surface your operations and onboarding stack talks to.

  • Onboard clients straight from your CRM
  • Open, group, and configure trading accounts
  • Process deposits, withdrawals, and adjustments
  • Power broker dashboards and back-office tooling
02Trader APIs

Trading Terminals & API Access

Ship a terminal. Or let your users bring their own bots.

Authenticate traders, stream prices, route orders, and read positions in real time. REST for request/response, WebSocket for the things that can’t wait.

  • Build custom web and mobile trading terminals
  • Stream quotes, order book, and account events
  • Place, modify, and cancel orders programmatically
  • Offer API trading to power users and algo desks
  • Pull positions, fills, and account history

Not sure which one you need? If you’re running the broker, start with Admin. If you’re building what the trader sees, start with Trader.
