# Broker API

> Build embedded investing infrastructure with MyStocks accounts, funding, KYC, trading, events, reporting, and reconciliation.

The Broker API is the end-to-end partner workflow for embedding investing into your product. It combines customer sub-accounts, USD wallets, funding and withdrawals, partner-asserted KYC, trading, webhooks, reports, and production certification.

## Recommended sequence

1. [Get credentials and understand environments](/partners/docs/auth).
2. Complete [Getting Started with Broker API](/partners/docs/getting-started-broker) in sandbox.
3. Create and manage [sub-accounts](/partners/docs/sub-accounts).
4. Add [funding and withdrawals](/partners/docs/fund-flow).
5. Add [webhooks and SSE events](/partners/docs/webhooks).
6. Build [reconciliation and reports](/partners/docs/reports).
7. Submit [go-live evidence](/partners/docs/going-live).
