Response

typescript

export type PrepareOwnerOperationResult = {
  chainId: number;
  account: string;
  operation: {
    policyKey: string;
    displayName: string;
    calls: Array<OwnerOperationCall & { selector: string }>;
  };
  policy: {
    authorization: string;
    sessionEligible: boolean;

Find nested types in the SDK reference. The client handles both a top-level response and a response wrapped in data.

Handling failures

Non-2xx responses become HazbaseWalletApiError. Record status, code and message, distinguishing API errors from network failures. Keep credentials out of logs.
