# Build with the Client Account API

Operate Axiym accounts owned by clients who complete onboarding with Axiym.

Product: Client Account API
Guides follow API reference 0.3.0 and event reference 0.2.0.
Canonical page: https://docs.sandbox.axiym.io/client-account-api

The Client Account API gives each onboarded client its own Axiym account context.
You use one set of partner credentials and operate each client’s balances,
deposits, currency conversions, and withdrawals through its `clientId`.

**When to use the Account API**

Use the [Account API](/account-api) instead when your
organization should own the Axiym accounts and operate them in one account
context.
