Google Apps Script call Address Validation API - google-apps-script

Question

Simple code and straightforward. It works with postman but fails with Apps Script.
function validateAddress () {
const url = 'https://addressvalidation.googleapis.com/v1:validateAddress?key=';
const apikey = '...';
let payload, options, temp;
payload = JSON.stringify({
"address": {
"addressLines": "1600 Amphitheatre Pkwy"
}
});
options = {
'muteHttpExceptions': true,
'method': 'POST',
'Content-Type': 'application/json',
'body': payload
}
temp = UrlFetchApp.fetch(url + apikey, options);
Logger.log(temp)
}
Error:
{
"error": {
"code": 400,
"message": "Address is missing from request.",
"status": "INVALID_ARGUMENT"
}
}
EDIT:
Change options to
options = {
'muteHttpExceptions': true,
'method': 'POST',
'Content-Type': 'application/json',
'payload': payload
}
Gives error:
{
"error": {
"code": 400,
"message": "Invalid JSON payload received. Unknown name \"{\"address\":{\"addressLines\":\"1600 Amphitheatre Pkwy\"}}\": Cannot bind query parameter. Field '{\"address\":{\"addressLines\":\"1600 Amphitheatre Pkwy\"}}' could not be found in request message.",
"status": "INVALID_ARGUMENT",
"details": [
{
"#type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"description": "Invalid JSON payload received. Unknown name \"{\"address\":{\"addressLines\":\"1600 Amphitheatre Pkwy\"}}\": Cannot bind query parameter. Field '{\"address\":{\"addressLines\":\"1600 Amphitheatre Pkwy\"}}' could not be found in request message."
}
]
}
]
}
}

Answer 1

From the documentation, it seems that addressLines is an array of string, not a string. Does that change something ? (I don't have a key, so I cannot try myself).
And more important, your options object is incorrect (check doc). It should be
options = {
'muteHttpExceptions': true,
'method': 'POST',
'contentType': 'application/json',
'payload': payload
}

Answer 2

I don't know why it works but changed options to
options = {
'muteHttpExceptions': true,
'method': 'POST',
'headers': {
'Content-Type': 'application/json'
},
'payload': payload
}
Solves the problem.
