Using google app script to send a message with my PMS's API - web-services

Question

Im using google app script to hopefully sent a message to my guests using my PMS (Smoobu). I think I have an issue with my syntax.
var smoobuPostOptions = {
"method": 'post',
"muteHttpExceptions": false,
"headers": {
"Api-Key": "???????????????????????????????????",
"cache-control": "no-cache",
"ContentType": "application/json",
},
"data": {
"subject": "Test Subject",
"messageBody": "Test Message"
}
}
var txTresponse = UrlFetchApp.fetch("https://login.smoobu.com/api/reservations/31418467/messages/send-message-to-guest", smoobuPostOptions);
var txtData = JSON.parse(txTresponse.getContentText());
The error I am getting is:
Exception: Request failed for https://login.smoobu.com returned code 500. Truncated server response: {"status":500,"title":"Internal Server Error","detail":"Zend\Form\Form::setData expects an array or Traversable argument; received "NULL""} (use muteHttpExceptions option to examine full response)
API Docs - https://docs.smoobu.com/#send-message-to-guest
I do believe I just need an example and I will be able to work it out!

Answer 1

From your provided document, it seems that you wanted to convert the following curl command to Google Apps Script.
curl -X POST \
'https://login.smoobu.com/api/reservations/1/messages/send-message-to-guest' \
-H 'Api-Key: secretApiKey' \
-H 'Content-Type: application/json' \
-H 'cache-control: no-cache' \
-d '{"subject" : "Test subject","messageBody" : "test"}'
In this case, how about the following modification?
From:
var smoobuPostOptions = {
"method": 'post',
"muteHttpExceptions": false,
"headers": {
"Api-Key": "???????????????????????????????????",
"cache-control": "no-cache",
"ContentType": "application/json",
},
"data": {
"subject": "Test Subject",
"messageBody": "Test Message"
}
}
To:
var smoobuPostOptions = {
"method": 'post',
"headers": {
"Api-Key": "???????????????????????????????????",
"cache-control": "no-cache",
},
"contentType": "application/json",
"payload": JSON.stringify({
"subject": "Test Subject",
"messageBody": "Test Message"
})
};
Note:
I think that the request of the above-modified script is the same as the sample curl command. But, if an error occurs, please confirm your endpoint, "Api-Key" and the request body again.

fetch(url, params)
