# `Twilio.Calls.Notifications`

API calls: `list`, `retrieve`.

# `list`

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

`GET /2010-04-01/Accounts/{AccountSid}/Calls/{CallSid}/Notifications.json`

## Path parameters

  * `call_sid` (required) - The [Call](https://www.twilio.com/docs/voice/api/call-resource) SID of the Call Notification resources to read.

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

## Parameters

  * `log` - Only read notifications of the specified log level. Can be: `0` to read only ERROR notifications or `1` to read only WARNING notifications. By default, all notifications are read.
  * `message_date` - Only show notifications for the specified date, formatted as `YYYY-MM-DD`. You can also specify an inequality, such as `<=YYYY-MM-DD` for messages logged at or before midnight on a date, or `>=YYYY-MM-DD` for messages logged at or after midnight on a date.
  * `message_date_query` - Only show notifications for the specified date, formatted as `YYYY-MM-DD`. You can also specify an inequality, such as `<=YYYY-MM-DD` for messages logged at or before midnight on a date, or `>=YYYY-MM-DD` for messages logged at or after midnight on a date.
  * `message_date_query_2` - Only show notifications for the specified date, formatted as `YYYY-MM-DD`. You can also specify an inequality, such as `<=YYYY-MM-DD` for messages logged at or before midnight on a date, or `>=YYYY-MM-DD` for messages logged at or after midnight on a date.
  * `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!(String.t(), map() | keyword(), keyword()) ::
  Twilio.Schemas.CallsNotificationsListResponse.t()
```

Like `list/3`, but returns the result or raises `Infusion.Runtime.Error`.

# `list_all`

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

Like `list/3`, but returns every item, from every page: a lazy stream of `Twilio.Schemas.CallNotification.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!(String.t(), map() | keyword(), keyword()) :: Enumerable.t()
```

Like `list_all/3`, but returns the stream or raises `Infusion.Runtime.Error`.

# `retrieve`

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

`GET /2010-04-01/Accounts/{AccountSid}/Calls/{CallSid}/Notifications/{Sid}.json`

## Path parameters

  * `call_sid` (required) - The [Call](https://www.twilio.com/docs/voice/api/call-resource) SID of the Call Notification resource to fetch.
  * `sid` (required) - The Twilio-provided string that uniquely identifies the Call Notification 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(), String.t(), keyword()) ::
  Twilio.Schemas.CallNotificationInstance.t()
```

Like `retrieve/3`, but returns the result or raises `Infusion.Runtime.Error`.
