Endpoint
POST /v3/onboarding/managed_accounts/list
Authentication and target
A user-scoped owner credential is required. The selected managed account must be visible through the user’s active Master Account relationship. This route does not become accessible merely by adding account-targeting headers. Do not send X-ISPB or X-Account-Number. This user-only management route rejects account-targeting headers.Request body
Success data
managed_accounts[] plus page with page, page_size, total, and total_pages.
Behavior and validation
Visibility is restricted to valid MOR, VA, and PA relationships under the owner’s active Master Account.Errors
Every call can fail for missing or invalid signature headers, an expired timestamp, nonce replay, an invalid body hash or signature, insufficient permission, or a downstream service error. Endpoint-specific errors include:field_invalidfor an unsupported model or status.invalid_userwhen an active Master context is unavailable.
