Downstream Response

Introduction

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

$response = $fcm->sendTo(['1', '2', '3', '4']);

You have seven methods available to read downstream response:

• getNumberSuccess(): Return the number of messages that were processed without an error.

$response->getNumberSuccess();

• getNumberFailure(): Return the number of messages that could not be processed.

$response->getNumberFailure();

• getNumberModify(): Return the number of results that contain a canonical registration token.

$response->getNumberModify();

• getTargetsToDelete(): Return an array of tokens that you should remove in your database.

$response->getTargetsToDelete();

• getTargetsToModify(): Return an array of tokens (key : old token, value : new token) that you should change in your database.

$response->getTargetsToModify();

• getTargetsToRetry(): Return an array of tokens you should try to resend the message.

$response->getTargetsToRetry();

• getTargetsWithError(): Return an array of tokens that could not be processed with their error.

$response->getTargetsWithError();
