Hi osemenyshyn,
Thanks for the reply. The exp should be the timestamp when the JWT token expires. And the unit for tokenExp is sec, and the minimum value should be issueTimestamp + 1800 (30 mins, no max), here is an example:
{
"appKey": "string", // Your SDK key
"iat": 1582774049,
"exp": 1582848000
"tokenExp": 1582776049 (1582774049 + 2000)
}
Hope this helps. Thanks!
