Google app scrips Slack API Get pins:list - json

Question

Using Google app script as serverless for a slack bot. Having an issue returning specific values from slack API. I'm using the pins:list call. I am able to get the JSON in response and items calls but get null when trying to get the next set of values. I am looking to return "permalinks" so I can then post back into slack what items are pinned to a room. here is my script:(without giving away company details)
function GetPinns() {
const ss = SpreadsheetApp.getActiveSpreadsheet()
let url = "https://slack.com/api/pins.list?channel=C0XXXXXXXXX&pretty=1";
let payload = {
"ok": true,
"channel": "C0XXXXXXXXX"
"type": "message",
}
var options = {
"method": "get",
"payload": JSON.stringify(payload),
"headers": {
"Content-type": "application/json; charset=utf-8",
"Authorization": "Bearer xoxb-"}}
var response = UrlFetchApp.fetch(url, options)
var json = response.getContentText();
var data = JSON.parse(json);
var items = data.item.permalinks;
Logger.log(items);
}
Thank you!!

SUGGESTION
Upon reviewing Slack's official docs for pins.list method, I suppose that this sample JSON response below is the same as the actual JSON response that you're getting:
Sample JSON response:
{
"items": [
{
"channel": "C2U86NC6H",
"created": 1508881078,
"created_by": "U2U85N1RZ",
"message": {
"permalink": "https://hitchhikers.slack.com/archives/C2U86NC6H/p1508197641000151",
"pinned_to": [
"C2U86NC6H"
],
"text": "What is the meaning of life?",
"ts": "1508197641.000151",
"type": "message",
"user": "U2U85N1RZ"
},
"type": "message"
},
{
"channel": "C2U86NC6H",
"created": 1508880991,
"created_by": "U2U85N1RZ",
"message": {
"permalink": "https://hitchhikers.slack.com/archives/C2U86NC6H/p1508284197000015",
"pinned_to": [
"C2U86NC6H"
],
"text": "The meaning of life, the universe, and everything is 42.",
"ts": "1503289197.000015",
"type": "message",
"user": "U2U85N1RZ"
},
"type": "message"
}
],
"ok": true
}
You can try iterating though the items array via looping in the JSON response to get each permalinks data, as seen on this quick test below:
Quick Test
function GetPinns() {
//This sample JSON String response was from https://api.slack.com/methods/pins.list#examples
var json =
"{\"items\": [{\"channel\": \"C2U86NC6H\",\"created\": 1508881078,\"created_by\": \"U2U85N1RZ\",\"message\": {\"permalink\": \"https://hitchhikers.slack.com/archives/C2U86NC6H/p1508197641000151\",\"pinned_to\": [\"C2U86NC6H\"],\"text\": \"What is the meaning of life?\",\"ts\": \"1508197641.000151\",\"type\": \"message\",\"user\": \"U2U85N1RZ\"},\"type\": \"message\"},{\"channel\": \"C2U86NC6H\",\"created\": 1508880991,\"created_by\": \"U2U85N1RZ\",\"message\": {\"permalink\": \"https://hitchhikers.slack.com/archives/C2U86NC6H/p1508284197000015\",\"pinned_to\": [\"C2U86NC6H\"],\"text\": \"The meaning of life, the universe, and everything is 42.\",\"ts\": \"1503289197.000015\",\"type\": \"message\",\"user\": \"U2U85N1RZ\"},\"type\": \"message\"}],\"ok\": true}";
var data = JSON.parse(json);
//Iterate through the items via looping
data.items.forEach(item => {
Logger.log(item.message.permalink)
});
}
Result
Your script will look like this:
function GetPinns() {
const ss = SpreadsheetApp.getActiveSpreadsheet()
let url = "https://slack.com/api/pins.list?channel=C0XXXXXXXXX&pretty=1";
let payload = {
"ok": true,
"channel": "C0XXXXXXXXX"
"type": "message",
}
var options = {
"method": "get",
"payload": JSON.stringify(payload),
"headers": {
"Content-type": "application/json; charset=utf-8",
"Authorization": "Bearer xoxb-"
}
}
var data = JSON.parse(json);
//Iterate through the items via looping
data.items.forEach(item => {
Logger.log(item.message.permalink)
});
}

Thank you!!
I wound up with this in the end
var response = UrlFetchApp.fetch(url, options);
var json = JSON.parse(response.getContentText());
var items = json.items
var linkList = ""
for(var x in items) {
var link = items[x]["message"]["permalink"]
var text = items[x]["message"]["text"]
linkList += "<" + link +"|" + text +">" + "\n"
}
