API Help in a Google Spreadsheet

I’ve been getting the API to work in a Google Spreadsheet Script and I’ve been working down all the examples in the API documentation and so far I’ve gotten a proper response back with the info I need. The last one I got to work was /public/zone/:id. (which the documentation example was wrong, “public/device/” should be “public/zone/”)

What I can’t get to work is /public/zone/start. Any idea how I would format that to work out of Google Apps Script?

This works and I get a response back:

function ZoneInfo() {
var APIKey = XXXXX;
var ZoneID = “1b9a8312-d9b3-4ffd-a0c5-6509c2a2c3bf”
var url = “https://api.rach.io/1/public/zone/”+ZoneID;
var headers = {
“contentType”: “application/json”,
“headers”:{“Authorization”: "Bearer " + APIKey}

var response = UrlFetchApp.fetch(url, headers);
var data = JSON.parse(response.getContentText());

You are making a GET request to “https://api.rach.io/1/public/zone/”+ZoneID endpoint, which correctly returns data on the zone in question. What you want is a POST request with zone id within the post data:

var APIKey = XXXXX;
var ZoneID = “1b9a8312-d9b3-4ffd-a0c5-6509c2a2c3bf”
// Make a POST request with a JSON payload.
var data = {
‘id’: ZoneID,
‘duration’: 60 // value in seconds; required
var options = {
‘method’ : ‘post’,
‘contentType’: ‘application/json’,
“headers”:{“Authorization”: "Bearer " + APIKey},
// Convert the JavaScript object to a JSON string.
‘payload’ : JSON.stringify(data)
var response = UrlFetchApp.fetch(‘https://api.rach.io/1/public/zone/start’, options);
var data = JSON.parse(response.getContentText());

I knew it had to be something where Get was the default. Your example almost worked, but I had to change POST into PUT

It successfully starts the zone, but I get the error below which isn’t really that big of a deal if it already did what I wanted it to… Any idea what to do with this?

[20-08-19 09:31:44:114 CDT] SyntaxError: Unexpected end of JSON input
at StartZone(asdf:39:19)

I’ve missed this, but zone / start endpoint does not respond with any data, thus unexpected end to the json string. If successful, response will have 204 code only:

var response = …;
if ( response.getResponseCode() == 204) { Logger.log(“Success”); }
else Logger.log("Unexpected response: " + response.getResponseCode());


I think I have everything working properly. I’m going to tweak this here and I’ll post a full writeup of how to do this in a Google sheet like I am. Thank you so much!
