Note

While we don’t impose a hard limit on the size of the recipients array, there is a limit of 1MB on the size of the request body posted to our servers. If you’re trying to send an announcement to a large number of your users, we recommend breaking it up into reasonably sized batches. If you see a 413 Request entity too large response, you’ll need to reduce the number of recipients you’re sending.
