Retrieving data from Pocket API (oAuth) - node.js

Question

I need to retrieve my saved reading list from my Pocket account
and it seems that I need to acquire access token through their oAuth to make a request.
I've got consumer key for the access token and as per Pocket API documentation, the request will resemble something like this.
POST /v3/oauth/request HTTP/1.1
Host: getpocket.com
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
X-Accept: application/x-www-form-urlencoded
consumer_key=1234-abcd1234abcd1234abcd1234&
redirect_uri=pocketapp1234:authorizationFinished
My question is... isn't oAuth for 3rd party apps to enable authentication via Google, Facebook account? I don't see how this idea is relevant for my website that will only require access to my own data from Pocket to share on my site.
I understand I will need to authenticate somehow so I can access my data but is oAuth the process I will need to go through to get what I need?

Answer 1

It seems that they support only 3 legged OAuth flow. You can use Grant in your NodeJS app, or just get access token from here.
Grant
save the following example to a file
set your key here: key:'...'
install the needed dependencies
run the file with node.js
navigate to http://localhost:3000/connect/getpocket
follow the instructions on screen
At the end you'll see your access_token.
var express = require('express')
, session = require('express-session')
var options = {
server: {protocol:'http', host:'localhost:3000'},
getpocket: {key:'...', callback:'/getpocket_callback'}
}
var Grant = require('grant-express')
, grant = new Grant(options)
var app = express()
app.use(session({secret:'very secret'}))
app.use(grant)
app.get('/getpocket_callback', function (req, res) {
console.log(req.query)
res.end(JSON.stringify(req.query, null, 2))
})
app.listen(3000, function () {
console.log('Express server listening on port ' + 3000)
})
}
Purest
Then you can use Purest to make requests to the Pocket's REST API.
var getpocket = new Purest({provider: 'getpocket'})
getpocket.query()
.post('get')
.auth('[API_KEY]', '[ACCESS_TOKEN]')
.request(function (err, res, body) {
// body is the parsed JSON response
})

Answer 2

For anyone reading this in 2021 or later, wanting to make a simple script to add articles to their pocket, I came up with this:
1: get your consumer key, via pocket's site.
2: get you access token, using this tool it's very simple. If you want to make an app or something that'll work without it, I guess the above (old) answer might work, didn't test it.
3: Use the following code to add an article:
var request = require('request');
request.post({
url: 'https://getpocket.com/v3/add',
form: {
url: 'https://articleToAdd.com',
consumer_key: '123456-12abcd1234a1ab12a12abc12',
access_token: '12345a1a-1ab1-1a12-12a1-1a1234'
}
},
function(err, httpResponse, body) { console.log(httpResponse.body) }
)
Hope it helps someone that is looking to do the same. Retrieving/modifying articles is similar, look here for the specifics.
