I am trying to access the Current powered by GE CityIQ API to develop a parking app, I followed the API documentation however I cannot seem to successfully query because I do not have an access token. I have a user name and password as well as the urls and predix zone id for parking provided by the city I am using. When I try and run my javascript and log my access token the response is “Unauthorized”. Do i have to raise a request to the city for the access token?

The code is written in javascript and is using node.js and node-fetch.

Here is my code:

const fetch = require("node-fetch")
function request(url, headers, body) 
 let options = headers: headers, body:body
 return fetch(url, options).then(result => 
 if (result.status>=400) return(result.statusText)
 else return result.text().then(txt => 
 try return JSON.parse(txt) 
 catch (err) return txt 
 )
 )

// my credentials
const developer, uaa, metadataservice, eventservice, predixZone

developer = 'user:pass'
uaa='uaaURL' 
eventservice='eventURL' 
metadataservice='metadataURL' 
predixZone='predixzoneParking' 

async function example(event)
 let devToken = (await request(uaa+'?grant_type=client_credentials', authorization: 'Basic '+developer))
 console.log(devToken)
 let output = (await request(metadataservice+'/assets/search?q=eventTypes:PKIN',authorization: 'Bearer '+devToken,'predix-zone-id':predixZone)).content
 console.log(output)

example()

What am I doing wrong or probably missing?

It looks like you have not base64 encoded your username and password.

At the top of your code:

const btoa = str => new Buffer(str).toString('base64')

When you declare your user name and pass:

developer = btoa('user:pass')
