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.
