laravel queue (retry jobs 5 times) & mark job as failed "manually" - exception

Question

I've got a queue running some callback requests to endpoint of my users.
Here's the code of my queue.
public function handle()
{
//send webrequest here....
//check the response of user backend
if ($res->getStatusCode() != 200 || $res->getBody()->getContents() != "*received*")
throw new Exception('callback url not reachable');
}
public function failed(Exception $exception)
{
//check tries and try again if needed
//check if job failed for 5 times
//if not ->retry again in 5 minutes, increment the times tried
//if yes ->disable API access, send email
Log::info("user email send, callback disabled!");
}
How to let the job fail (my current exception makes the whole job end), when webrequest answer is != "received" and check if the certain job failed 5 times?
If a job failed it should be tried again in 5 minutes.
I don't understand the doc regarding these points.

Answer 1

I know it's too late but yesterday I had the same problem with the queue and when I throw a new exception the queue run it again and again until my VM hanged up. actually, you did right the only thing you have to add to your code is define a tries variable to the public area of your job class and it should run only for example 5 times and pushed to failed job ;)
class NewCustomer implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public $tries = 5;
