read objects in ibm cloud object storage using api key

Question

I am able to read files in bucket in COS using IAM token but unable to do the same using API key. I have set the following key in my request header:

Authorization: {api key}

Should I set anything else? Note I am not using HMAC credentials. below code has two options one with bearer token and the other with api key created for that Cos instance specifically for the bucket.

example code:

var request = require('request');

//using bearer token

var options = {

uri: 'https://{endpoint}/{bucket name}',
headers: {
'Authorization': 'bearer {token string}',
}
};

//using api key

var options = {
uri: 'https://{endpoint}/{bucketname}',
headers: {
'Authorization': '{{api key string for cos service id}',
}
};

function callback(error, response, body) {
console.log(error)
console.log(response.statusCode)
if (!error && response.statusCode == 200) {
console.log(body)
}
}

 request(options, callback);

Just use the ibm-cos-sdk npm library here https://www.npmjs.com/package/ibm-cos-sdk. You just have to do the following and you're on your way.

var AWS = require('ibm-cos-sdk');
var util = require('util');

var config = {
    endpoint: '<endpoint>',
    apiKeyId: '<api-key>',
    ibmAuthEndpoint: 'https://iam.ng.bluemix.net/oidc/token',
    serviceInstanceId: '<resource-instance-id>',
};

var cos = new AWS.S3(config);
