# init(fineConversionValue:lockPostback:coarseConversionValue:conversionTypes:)

Creates a new postback update with the conversions values, conversion types, and lock indication you provide.

```
init(fineConversionValue: Int, lockPostback: Bool, coarseConversionValue: CoarseConversionValue? = nil, conversionTypes: [PostbackUpdate.ConversionType]? = nil)
```

## Parameters

`fineConversionValue`

An integer that represents the fine conversion value.

`lockPostback`

A Boolean value that indicates whether the system can lock the postback, reducing the system time
to deliver a signal.

`coarseConversionValue`

An optional `CoarseConversionValue` enumeration value that represents the
coarse conversion value. Defaults to `nil`.

`conversionTypes`

An optional array of conversion types the system uses to determine which postbacks to update.
Defaults to `nil` and the system updates all types of postbacks by default.
