Endpoint
POST /v3/onboarding/managed_accounts/credentials/rotate
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. The account selector documented below belongs in the JSON request body.Request body
Send exactly one ofreference_id or account.
Success data
No successful credential payload is implementation-backed today. Although the compiled contract contains reserved new-credential and old-key-expiry fields, the current service returns before producing them.Behavior and validation
Every valid call currently returns the unsupported-operation business error (business code 503 in the normal HTTP 200 envelope). The human-readable message is localized; do not branch on it. Do not build a production rotation workflow around this endpoint until the service implementation changes and the documentation is revised.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:invalid_parameterfor an invalid selector.- Business code 503 for the implemented unsupported-operation branch. The normal transport status remains HTTP 200; the localized message is not a stable machine identifier.
