Topic Response

Introduction

To get the response of a topic request, just save the return of the sendToTopic() method into a variable.

$response = $fcm->sendToTopic($topic);

You have three methods available to read downstream response:

• isSuccess(): Return true if topic was sent with success.

$response->isSuccess();

• shouldRetry(): Return true if topic must be resent.

$response->shouldRetry();

• getError(): Return the error message if topic couldn’t be sent.

$response->getError();
