Trying to access Indeed API using HTTR ( R Programming) - r

I am a API newbie trying to access a certain webpage on Indeed.Com website using it's API for my employer.I am not able to receive token once I am sending the CLIENT ID AND SECRET ID.Any help is appreciated.
The Indeed API documentation : http://opensource.indeedeng.io/api-documentation/docs/oauth/#before-you-start
Indeed Employer API : https://employers.indeed.com/api/v1
options("httr_oob_default" = T)
options("httr_oauth_cache"= T)
Sys.setenv("HTTR_SERVER_PORT" = "1410/")
library(httr)
library('httpuv')
#Token Request URL
request_url = 'https://secure.indeed.com/'
#Token Access URL
access_url = 'https://secure.indeed.com'
#Authorization URL
authorization_url = 'https://secure.indeed.com/account/oauth?client_id="Your client ID" &redirect_uri=http://localhost:1410/&response_type=code'
#Saving client ID and Secret ID
key <- 'YOUR CLIENT ID'
secret <- 'CLIENT SECRET ID'
#Sending OAUTH Request
myinapp = oauth_app(NULL, key, secret)
in_app = oauth_endpoint(request_url, authorization_url, access_url)
#Getting Token
token = oauth1.0_token(in_app, myinapp)
#Authenticating Token
mytoken = config(token = token)

R httr - Error Getting API OATH Token - Missing grant_type

I am trying to test out the Dun and Bradstreet API in R using httr.
I am trying to leverage the oauth2 functionality in httr.
Here is my code:
library(httr)
library(jsonlite)
clientid = redacted
secret = redacted
app <- oauth_app(appname = "Dun", key = clientid, secret = secret)
endpoint <- oauth_endpoint(base_url = "https://login.bisnode.com/sandbox/v1/token.oauth2", authorize="https://login.bisnode.com/sandbox/v1/token.oauth2", access = "https://login.bisnode.com/sandbox/v1/token.oauth2")
token <- oauth2.0_token(endpoint = endpoint, app = app, scope = "credit_data_companies", user_params = list(grant_type = "client_credentials"))
In Rstudio I get this message:
Waiting for authentication in browser... Press Esc/Ctrl + C to abort
In the browser, I get this message:
{"error":"invalid_request","error_description":"grant_type is
missing"}
I am sure this is something simple, but I could not find a solution in any other posts. Thank you!

REST API to stocktwits.com in R

I have been banging my head over this the whole day. I am trying to access StockTwits API (https://api.stocktwits.com/developers) from an R session. I have earlier accessed the twitter API (via rtweet) without hassles.
I have created an app and got the client id and key (the below are just examples).
app_name = "some.name";
consumer_key = "my_client_id";
consumer_secret = "my_client_key";
uri = "http://iimb.ac.in" # this is my institute's homepage. It doesn't allow locahost OR 127.0.0.1
scope = "read,watch_lists,publish_messages,publish_watch_lists,direct_messages,follow_users,follow_stocks";
base_url = "https://api.stocktwits.com/api/2/oauth"; # see https://api.stocktwits.com/developers/docs/api
The procedure is to create an oauth2.0 app and endpoint. Then call oauth2.0_token.
oa = httr::oauth_app(app_name, key = consumer_key, secret = consumer_secret, redirect_uri = uri);
oe = httr::oauth_endpoint("stocktwits", "authorize", "token", base_url = base_url);
mytoken = httr::oauth2.0_token(oe, oa, user_params = list(resource = base_url), use_oob = F); # use_oob = T doesn't work.
After firing the above, it takes me to the browser for sign-in. I sign-in and it asks me to connect. After that, I am taken back to my URI plus a code, i.e. https://www.iimb.ac.in/?code=295ea3114c3d8680a0ed295d52313d7092dd90ae&state=j9jXzEqri1
Is the code my access token or something else? The oauth2.0_token() call keeps waiting for the code since the callback is not localhost. I didn't seem to get a hang of that.
I then try to access the API using the above code as access token but I am thrown "invalid access token" error. The format is described in https://api.stocktwits.com/developers/docs/api#search-index-docs
Can someone tell me what I have missed? If required I can share my app_name, consumer_key and consumer_secret for replication.

Access Reddit API using OAuth2 in R: how to request and update token

Resolved
I am using the following R code to acquire a token from Reddit API on behalf of a user. However, tokens expire in an hour. To keep access with that app, I need to use a refresh_token parameter that I would receive with a first request, I understand. However, for some reason, I cannot receive a refresh_token using the following code:
#API app settings reddit:
endpoint <- oauth_endpoint(
authorize = "https://www.reddit.com/api/v1/authorize",
access = "https://www.reddit.com/api/v1/access_token"
)
appName <- "xxx"
key <- "xxx"
secret <- "xxx"
app <- oauth_app(appName, key, secret)
# authenticate using OAuth2 [an issue with token]
token <- oauth2.0_token(
endpoint = endpoint,
app=app,
scope = c("read"),
user_params = list(duration = "permanent"),
use_basic_auth = TRUE,
config_init = user_agent("Testing"),
cache = TRUE
)
That's how the resulted token looks like:
print(token$credentials)
$access_token
[1] "xxx"
$token_type
[1] "bearer"
$expires_in
[1] 3600
$scope
[1] "read"
Would anybody please suggest how to improve this request?
The request should include duration = "permanent" attribute in query_authorize_extra field
Here is a corrected request:
token <- oauth2.0_token(
endpoint = endpoint,
app=app,
scope = c("read"),
query_authorize_extra = list(duration = "permanent"),
use_basic_auth = TRUE,
config_init = user_agent("Testing"),
cache = TRUE
)
In one hour, token updates itself automatically ones a get or other type of request sent

HTTP API Authentification in R via 0auth

I got some problems accessing tracking API via 0auth;
I have sign key, secret and Authorization_key.
Sign key and secret should form a sig file as I understand and authorization_key that should be added as header.
The code:
auth_info <-
read.csv2('./Data/auth_info.csv',
encoding = 'UTF-8',
stringsAsFactors = F)
express <-
oauth_app("express", key = 'Ur1475', secret = auth_info$sign_key)
sig <- sign_oauth1.0(express)
order <-
GET(
"http://www.express.ru/api/v2/getOrder?orderNumber=WEBN3141018",
authenticate("Ur1475", auth_info$sign_key),
add_headers(Authorization = auth_info$auth_key),
sig
)
order_info <- content(order)
order_info
Returns me auth error;
Official api documentation tells that should be formed md5(client key . URL . GET params . POST params . sign key).
Also I've looked at 0auth function code it does not use http.
Could it cause the problem?
Could you please comment on how to get data from API via R?
API doc (in russian)): https://www.express.ru/docs/APIExpressRu.pdf
The major of API's (Google, Twitter, Facebook) need a token that you must to obtain from an oauth authentication. Depending from the API's you must to use the functions GETor POST. And you must to provide your key encoded in base64. So what I think you need is:
First: Authenticate.
if(!require("jsonlite")){library("jsonlite")}
if(!require("httr")){library("httr")}
#Create your own appication key
consumer_key <- "your consumer key" #needed
consumer_secret <- "your consumer secret" #some api's don't need.
#Use basic auth
secret <- jsonlite::base64_enc(paste(consumer_key, consumer_secret, sep = ":"))
req <- httr::POST("https://url.of.your.api/oauth/token", #"oauth" and "token" are not parameters, they are fixed.
httr::add_headers(
"Authorization" = paste("Basic", gsub("\n", "", secret)),
"Content-Type" = "application/x-www-form-urlencoded;charset=UTF-8"
),
body = "grant_type=client_credentials"
)
#Extract the access token
token <- paste("Bearer", httr::content(req)$access_token)
Next: Make a request.
url<-"http://url.of.your.api/search?parameter1=value&parameter2=value"
req <- httr::POST(url, httr::add_headers("Authorization" = token))
json <- httr::content(req)
json
As I said, some API's need GETand others POST, try both.

QuickBooks OAuth API (401) Unauthorized

Here is the OAuth library I'm using: https://github.com/danielcrenna/oauth
I'm getting the token, secret and realmId (company id) just fine and storing them, but when I go to do a simple request, I get (401) Unauthorized.
Here's the code I'm using:
var rq = new OAuthRequest
{
Method = "GET",
Type = OAuthRequestType.ProtectedResource,
SignatureMethod = OAuthSignatureMethod.HmacSha1,
ConsumerKey = ConfigurationManager.AppSettings["ConsumerKey"],
ConsumerSecret = ConfigurationManager.AppSettings["ConsumerSecret"],
Token = requestToken,
TokenSecret = requestTokenSecret,
RequestUrl = "https://quickbooks.api.intuit.com/v3/company/" + realmId + "/query?query=select%20%2A%20from%20CompanyInfo&minorversion=4",
Version = "1.0",
};
And the Auth header:
OAuth oauth_consumer_key="****",oauth_nonce="6su4ljd2is5bxns4",oauth_signature="0taFXiouzOkpK258tz%2Fc%2F2fVQ0c%3D",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1461339515",oauth_token="****",oauth_version="1.0"
I can't find any other details in the error, I'm just getting "401 Unauthorized." How do I get this request to go through?
Oauth is pretty strict in how the header is written. Why not use one of the Libraries already provided by Intuit? or use the API Explorer to view the header and compare to your request header?
The order of the oauth header parameters matter, and version is not the last one. See this guide.
