If your system implementation involves an authentication step, use LPAuthenticationParams.

There are 2 authenticated connection methods:

  • Authenticated (authenticationKey)

  • Unauthenticated

public static void registerLPPusher(String brandId, String appId, String gcmToken, LPAuthenticationParams authenticationParams, final ICallback<Void, Exception> registrationCompletedCallback)
Parameter Description
brandId The account ID, for example, 652838922.
appId The host app ID, for example, com.liveperson.myApp.
gcmToken The GCM Token. Usually used to pass the Google provided token. However, this parameter can contain any string value. If you use the gcmToken as a custom value, you need to handle the mapping between this custom value and the actual gcm token in your server.
authenticationParams An optional parameter that enables registering without first opening a conversation.
registrationCompletedCallback An optional callback on the registration status.

Authenticated (authenticationKey)

Call LPAuthenticationParams().setAuthKey("yourAuthCode") to allow the LivePerson backend to verify the authentication token sent by the SDK with your system servers. If the key cannot be verified on your company’s backend servers, this call fails.

Note: When using this method, you can also set a special redirect URL when authenticating by calling: lpAuthenticationParams.setHostAppRedirectUri(yourRedirectUrl) with jwt - new LPAuthenticationParams().setHostAppJWT("yourJwt").

When using registerLPPusher with authentication parameters for JWT renewal (JWT renewal when in the background), the authentication process goes into an infinite loop. Use updateTokenInBackground to separate the register to push and the token update when in the background.

When the JWT expires or if the registration fails due to an expired token, the onTokenExpired() callback gets called.

  • If the screen is in the background, the host app uses the updateTokenInBackground() API with new authentication parameters instead of calling registerLPPusher().

  • If the screen is in the foreground, the host app calls reconnect() to renew the JWT.

Code sample

 public void onTokenExpired() {

 String jwt = generateNewJwt(); // A host app method

 LivePerson.updateTokenInBackground("1234567", new LPAuthenticationParams().setAuthKey(jwt));



Pass null or an empty LPAuthenticationParams.
