### Create an execution using shortcut syntax (v1 after upgrade)

Source: https://www.twilio.com/docs/studio/rest-api/v2

This example shows the shortcut syntax without a version indicator. After upgrading to the latest SDK, this code will automatically reference the v2 API, which may be unexpected.

```javascript
client.studio.flows('FWXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX')
             .executions
             .create({to: '+15558675310', from: '+15017122661'})
             .then(execution => console.log(execution.sid));
```

### Liquid for loop with limit and offset

Source: https://www.twilio.com/docs/studio/user-guide/liquid-template-language

Use limit and offset arguments to restrict which items are iterated. This example starts at the third item (offset:2) and takes two items (limit:2), resulting in 3 and 4.

```liquid
# array = [1,2,3,4,5,6]
{% for item in array limit:2 offset:2 %}
  {{ item }}
{% endfor %}
# results in 3,4
```

### Create Studio Flow Execution with Parameters (C#, Java, Go, PHP)

Source: https://www.twilio.com/docs/studio/rest-api/v2/execution

Create a Studio Flow execution with parameters using the Twilio helper libraries. Each example initializes the client with API key and secret from environment variables, then calls the create method with the flow SID, To, From, and a parameters map containing "foo": "bar". The resulting execution SID is printed.

```csharp
// Install the C# / .NET helper library from twilio.com/docs/csharp/install

using System;
using Twilio;
using Twilio.Rest.Studio.V2.Flow;
using System.Threading.Tasks;

        // and set the environment variables. See http://twil.io/secure
        // For local testing, you can use your Account SID and Auth token
        string apiKey = Environment.GetEnvironmentVariable("TWILIO_API_KEY");
        string apiSecret = Environment.GetEnvironmentVariable("TWILIO_API_SECRET");
        string accountSid = Environment.GetEnvironmentVariable("TWILIO_ACCOUNT_SID");

        TwilioClient.Init(apiKey, apiSecret, accountSid);

        var execution = await ExecutionResource.CreateAsync(

### List Studio Flows with twilio-cli and curl

Source: https://www.twilio.com/docs/studio/rest-api/flow

List Studio Flows using the twilio-cli command `twilio api:studio:v1:flows:list` and a raw curl GET request to the Studio API endpoint. The curl example uses the TWILIO_API_KEY and TWILIO_API_SECRET environment variables for basic authentication.

```bash
# Install the twilio-cli from https://twil.io/cli

twilio api:studio:v1:flows:list
```

```bash
curl -X GET "https://studio.twilio.com/v1/Flows?PageSize=20" \
-u $TWILIO_API_KEY:$TWILIO_API_SECRET
```

--------------------------------

### Unless statement

Source: https://www.twilio.com/docs/studio/user-guide/liquid-template-language

The unless tag is the reverse of an if statement. This example is equivalent to the previous if user.name != 'tobi' example. Do not use elsif or else with unless.

```liquid
# Same as above
{% unless user.name == 'tobi' %}
  Hello non-tobi
{% endunless %}
```
