# Get Raw Transaction To Execute

The TxnData type combines transaction metadata with network-specific transaction details for different blockchain networks (EVM, Solana, Cosmos, Tron)

Call this api with `routeId` and `stepId` of individual steps to get the transaction data to execute. Once the transaction is executed, check the status of the transaction using `/status` api and proceed to the next step of the transaction.

> Note: you can ignore status check and skip to next step of the txn if `skipTxn` field is set to `true` in the response. Also, when `skipTxn` is set to `true`, `txnData` will be `null`.

### Endpoint: `GET /nextTx` 

### Query params

```
/nextTx?
    routeId=
    &stepId=
```

### Response

```typescript
{
    routeId: string;
    stepId: string;
    txnData: TxnData | null;
    skipTxn?: boolean;
}
```
