Blogger API - Google Scripts Access Token - api

Question

I found this code here but I can't figure out where to get this ?
"headers" : { "Authorization" : "Bearer YOUR_ACTIVE_TOKEN"}
I have looked and researched every where but I can't find how to get this "Active Token". Can some one please help me to get this ?
function testBlogger() {
var payload =
{
"kind": "blogger#post",
"blog": {
"id": "YOUR_BLOG_ID"
},
"title": "New post",
"content": "With content..."
};
var options =
{
"method" : "post",
"headers" : { "Authorization" : "Bearer YOUR_ACTIVE_TOKEN"},
"contentType" : "application/json",
"payload" : '{ "kind": "blogger#post", "blog": { "id": "YOUR_BLOG_ID" }, "title": "New post", "content": "With content..." }'
};
try {
var result = UrlFetchApp.fetch(
"https://www.googleapis.com/blogger/v3/blogs/YOUR_BLOG_ID/posts",
options);
Logger.log(result);
} catch (e) {
Logger.log(e);
}
}

Answer 1

It involves a few more steps. You need to include the OAuth2 library in your project, enable the Blogger API in the Google Developers console and also create a new a browser key to get your client ID and secret.
var options =
{
"method" : "post",
"headers" : { "Authorization" : "Bearer " + getService().getAccessToken()},
"contentType" : "application/json",
"payload" : '{ "kind": "blogger#post", "blog": { "id": "YOUR_BLOG_ID" }, "title": "New post", "content": "With content..." }'
};

Answer 2

There are multiple steps required to initially setup the code environment to access OAuth2 APIs. In summary
Add an OAuth2 client library to your script project
Enable the Blogger API in the script project's associated Google Developers Console project
Setup a OAuth service in your script project
Authenticate access to generate the tokens
