# `create!`

```elixir
@spec create!(map() | keyword(), keyword()) :: Twilio.Schemas.Application.t()
```

Like `create/2`, but returns the result or raises `Infusion.Runtime.Error`.

# `delete`

```elixir
@spec delete(String.t(), keyword()) ::
  {:ok, nil} | {:error, Infusion.Runtime.Error.t()}
```

Delete the application by the specified application sid

`DELETE /2010-04-01/Accounts/{AccountSid}/Applications/{Sid}.json`

## Path parameters

  * `sid` (required) - The Twilio-provided string that uniquely identifies the Application resource to delete.

`{AccountSid}` in the path is the `:account_sid` setting; pass `account_sid: "..."` as an option to use another.

# `delete!`

```elixir
@spec delete!(String.t(), keyword()) :: nil
```

Like `delete/2`, but returns the result or raises `Infusion.Runtime.Error`.

# `list`

```elixir
@spec list(map() | keyword(), keyword()) ::
  {:ok, Twilio.Schemas.ApplicationsListResponse.t()}
  | {:error, Infusion.Runtime.Error.t()}
```

Retrieve a list of applications representing an application within the requesting account

`GET /2010-04-01/Accounts/{AccountSid}/Applications.json`

`{AccountSid}` in the path is the `:account_sid` setting; pass `account_sid: "..."` as an option to use another.

## Parameters

  * `friendly_name` - The string that identifies the Application resources to read.
  * `page_size` - How many resources to return in each list page. The default is 50, and the maximum is 1000.
  * `page` - The page index. This value is simply for client state.
  * `page_token` - The page token. This is provided by the API.

To read every item across all pages, use `list_all`.

# `list!`

```elixir
@spec list!(map() | keyword(), keyword()) ::
  Twilio.Schemas.ApplicationsListResponse.t()
```

Like `list/2`, but returns the result or raises `Infusion.Runtime.Error`.

# `list_all`

```elixir
@spec list_all(map() | keyword(), keyword()) ::
  {:ok, Enumerable.t()} | {:error, Infusion.Runtime.Error.t()}
```

Like `list/2`, but returns every item, from every page: a lazy stream of `Twilio.Schemas.Application.t()` that fetches pages as it is read.

The first page is fetched right away, so its errors are returned; a later page that fails raises `Infusion.Runtime.Error`. Stopping early (`Enum.take/2`) fetches no more pages.

# `list_all!`

```elixir
@spec list_all!(map() | keyword(), keyword()) :: Enumerable.t()
```

Like `list_all/2`, but returns the stream or raises `Infusion.Runtime.Error`.

# `retrieve`

```elixir
@spec retrieve(String.t(), keyword()) ::
  {:ok, Twilio.Schemas.Application.t()} | {:error, Infusion.Runtime.Error.t()}
```

Fetch the application specified by the provided sid

`GET /2010-04-01/Accounts/{AccountSid}/Applications/{Sid}.json`

## Path parameters

  * `sid` (required) - The Twilio-provided string that uniquely identifies the Application resource to fetch.

`{AccountSid}` in the path is the `:account_sid` setting; pass `account_sid: "..."` as an option to use another.

# `retrieve!`

```elixir
@spec retrieve!(String.t(), keyword()) :: Twilio.Schemas.Application.t()
```

Like `retrieve/2`, but returns the result or raises `Infusion.Runtime.Error`.

# `update`

```elixir
@spec update(String.t(), map() | keyword(), keyword()) ::
  {:ok, Twilio.Schemas.Application.t()} | {:error, Infusion.Runtime.Error.t()}
```

Updates the application's properties

`POST /2010-04-01/Accounts/{AccountSid}/Applications/{Sid}.json`

## Path parameters

  * `sid` (required) - The Twilio-provided string that uniquely identifies the Application resource to update.

`{AccountSid}` in the path is the `:account_sid` setting; pass `account_sid: "..."` as an option to use another.

## Parameters

  * `api_version` - The API version to use to start a new TwiML session. Can be: `2010-04-01` or `2008-08-01`. The default value is your account's default API version.
