file you'll need:

"sub" This is your site's admin email address

(e.g. "mailto:admin@example.com")

"exp" This is the expiration time for the claim in seconds. If you don't

have one, I'll add one that expires in 24 hours.

You're also welcome to add additional fields to the claims which could be

helpful for the Push Service operations team to pass along to your operations
|

team (e.g. "ami-id": "e-123456", "cust-id": "a3sfa10987"). Remember to keep

these values short to prevent some servers from rejecting the transaction due
|

to overly large headers. See https://jwt.io/introduction/ for details.
