# Master Accounts

> Create and manage master-account onboarding records.

Master accounts are top-level onboarding records. Creation, listing, and update operations require a platform credential. Detail lookup accepts a platform credential or an owner user credential when the implementation can resolve that ownership.

### Endpoints

* Create master account — `POST /v3/onboarding/master_accounts/create`
* Get master account — `POST /v3/onboarding/master_accounts/detail`
* List master accounts — `POST /v3/onboarding/master_accounts/list`
* Update master account — `POST /v3/onboarding/master_accounts/update`

### Authentication

All requests use the HMAC-SHA256 request-signing headers. Account-targeting headers are not a substitute for the required platform or owner credential policy.
