# configure

Initialization data is provided by certain payment methods, which can include a bank list or a list of retail outlets.

This data plays a crucial role in configuring the initial state of the application and offering users a selection of options.

If the data is available, an instance of `PrimerInitializationData` will be returned; otherwise, `null` will be returned.

Please refer to the following section to find the supported types of `PrimerInitializationData` that may be returned.

In case data cannot be obtained, Primer SDK will return `PrimerError`.

```kotlin KOTLIN theme={"dark"}
fun configure(completion: (PrimerInitializationData?, PrimerError?) -> Unit)
```
