Cron-Job.org integration with appsheet

[Hussein_Osseily]

Hello Community, 

For the users who use CronJob to interact with appsheet API, I was messing around with Cron-Job.org but failed to call an appsheet data action from there. Even though same action was successfully called using postman .

I used the URL that i always use to call the API whether in call a webhook via appsheet or postman. 
In the advanced section, I selected POST and in the response body i used the a json format to call the action but the error i got was error 415 Unsupported Media Type: 

{
"Action": "Test",
"Properties": {},
"Rows": [
{
"ID": 1
}
]
}

Thanks for any tips here.
