Max. number of token to send notification to?

[baden32]

In the sample code, we can see
$deviceTokens = ['<device_token_1>', '<device_token_2>', '<device_token_3>'];

At this time, for me it works fine for 3 tokens, all devices received the message.

So my question: is there a max. number of token I can send the notification at the same time?

If I have 4000 receivers, coud I add my 4000 tokens at a time and then call the push function or should I split into smallest packages (ie 1000 receivers)?

Thank you in advance for your help.

I didn't try to send so many notifications so I can't say for sure

Yes, you can put in thousands of tokens into the request.

Just to share some stats that I have after using this library. The old binary-method (sending to gateway.push.apple.com) which may/will be discontinued by Apple on 31-Mar-2021, is still the fastest way.
