# create\_transaction

## Installation

```bash
pip install karrotcapital.spiderswap
```

## Usage

### Initialization

First, initialize the **`'Spiderswap'`** class with your API key.

```python
from karrotcapital.spiderswap import Spiderswap

spiderswap = Spiderswap(ApiKey);
```

### Method: create\_transaction

**Description**

The **`'create_transaction'`** method creates a Solana transaction from a base64-encoded string containing the swap transaction data.

**Parameters**

* **`'swap_transaction_data'`** (str): The base64-encoded string containing the swap transaction data.

#### Returns

**`'VersionedTransaction'`**: A promise that resolves to a **`'VersionedTransaction'`** object.

#### Example

This example demonstrates using both **`'get_swap'`** and **`'create_transaction'`** methods.

```python
async def perform_swap_and_create_transaction():
    try:
        swap_result = await spiderswap.swap.get_swap(
            'owner_address',
            'from_mint_address',
            'to_mint_address',
            1000000,      # Amount in tokens
            50,           # Slippage percentage
            'provider',
            'pool',
            9             # From Mint Decimals
        );
        print(f"Swap Data: {swap_result}");
        
        transaction = await spiderswap.swap.create_transaction(
            swap_result['base64Transaction']
        )
        print(f"Transaction: {transaction}");
    except Exception as e:
        print(f"An error occurred: {e}")

perform_swap_and_create_transaction();
```

**Implementation Details**

This method converts the **`'swap_transaction_data'`** from a base64-encoded string to a buffer and deserializes it into a **`'VersionedTransaction'`**.
