# Using Dynamic URL Parameters in TaoDex

This guide explains how builders, validators, and subnet owners can use dynamic URL parameters on [taodex.hotkeyswap.com](https://taodex.hotkeyswap.com/) to interact with the platform effectively.

With these parameters, you can predefine the input and output subnets, as well as select a validator dynamically, making it easier to share specific links and automate actions.

***

### URL Structure

TaoDEX supports the following URL parameters:

{% code overflow="wrap" fullWidth="true" %}

```markup
https://taodex.hotkeyswap.com/dtao?inputNetuid=<input_netuid>&outputNetuid=<output_netuid>&validator=<validator_ss58>
```

{% endcode %}

#### Parameters:

* **`inputNetuid`**: Represents the netuid of the input subnet.
* **`outputNetuid`**: Represents the netuid of the output subnet.
* **`validator`**: Represents the validator's SS58 address.

⚠️ **Important Rules:**

* Only **one** of `inputNetuid` or `outputNetuid` can be set at a time.
* If `inputNetuid` is set, `outputNetuid` must be empty, and vice versa.
* The URL dynamically updates as users interact with the UI.

***

### Examples

#### Example 1: Setting an Input Subnet

To preselect an **input subnet** with `netuid=8`:

{% code overflow="wrap" %}

```markup
https://taodex.hotkeyswap.com/dtao?inputNetuid=8
```

{% endcode %}

#### Example 2: Setting an Output Subnet

To preselect an **output subnet** with `netuid=8`:

{% code overflow="wrap" %}

```markup
https://taodex.hotkeyswap.com/dtao?outputNetuid=8
```

{% endcode %}

#### Example 3: Selecting a Validator

To preselect a **validator** with `RoundTable21`:

{% code overflow="wrap" %}

```markup
https://taodex.hotkeyswap.com/dtao?validator=5FFApaS75bv5pJHfAp2FVLBj9ZaXuFDjEypsaBNc1wCfe52v
```

{% endcode %}

#### Example 4: Full Configuration

Setting both an **output subnet and a validator**:

{% code overflow="wrap" %}

```markup
https://taodex.hotkeyswap.com/dtao?outputNetuid=8&validator=5FFApaS75bv5pJHfAp2FVLBj9ZaXuFDjEypsaBNc1wCfe52v
```

{% endcode %}

***

### How It Works

1. **URL Updates Dynamically**
   * As users change subnets or validators, the URL updates automatically.
   * Clicking "Switch" will swap input and output subnets while maintaining the correct URL structure.
2. **Sharing Links**
   * Users can copy and share the URL to direct others to the same subnet and validator selection.
3. **Developers & Integrations**
   * Projects can integrate TaoDEX with predefined URLs for seamless user experience.

***

### Troubleshooting

* If **both** `inputNetuid` and `outputNetuid` appear, one must be removed manually.
* If switching input and output doesn't reflect in the URL, refresh the page and try again.
* For support, contact us.
