# StatusCodes

> The StatusCodes enum returned in responses.

Returned in responses (e.g. approval, trade) for programmatic handling:

```typescript theme={null}
import { StatusCodes } from "@dzapio/sdk";

StatusCodes.UserRejectedRequest;   // 4001 - User rejected in wallet
StatusCodes.Success;                // 200
StatusCodes.FunctionNotFound;      // 32771 - 0x8003
StatusCodes.Error;                  // 500
StatusCodes.WalletRPCFailure;      // 429
StatusCodes.SimulationFailure;     // 417
StatusCodes.ContractExecutionError; // -500
```
