# OIDC Federation support for your Android app

The DigipassONE App SDK for Android provides an interface to integrate FIDO authentication into an existing OIDC Federation infrastructure. Use this interface as an OIDC Federation client. After an end user authenticates and your app receives the AuthenticationData object from the App SDK, initiate the OIDC flow:

```plaintext
val config = OidcFederationClient.OidcFederationParams();
config.authFlowUrl = "<OIDC_AUTH_URL>"
config.federationResumeUrl = "<OIDC_RESUME_URL>"
config.tokenUrl = "<OIDC_TOKEN_URL>"
config.jwt = Model.sessionData?.get("sessionKey").toString()
val client = OidcFederationClient(config, this)
client.performCodeGrantFlow().then { result ->
    Log.i(TAG, "Code Grant flow completed successfully")
    val oidcResult = result as OidcResult
    Log.d(TAG, "id_token :" + oidcResult.id_token)
    Log.d(TAG, "refresh_token :" + oidcResult.refresh_token)
}.error {  exception ->
    Log.e(TAG, "OIDC code grant flow failed", exception as Exception)
}
```

Class OidcFederationClient contains methods that support the following OIDC flows:

- Authorization code grant
- Implicit
- Token refresh

**Working example in Tutorial App**

- MainActivity.kt shows how to initiate OIDC flows.
