Sending POST instead of GET request to Google Contacts API (OAuth2) - oauth-2.0

Hoping someone can help me out here. I'm using Google Contacts API to fetch a list of contacts. To my understanding, this is done by sending a GET request:
https://www.google.com/m8/feeds/contacts/default/full?alt=json&max-results=9999&oauth_token=OATH_TOKEN_HERE
However, this is wildly insecure as any intruder can gain access to the oauth_token in the URL. To combat this, I'm trying to send this as a POST request with my parameters (alt, max-results, oauth_token) as the data. However, I simply get an error that "Authorization is required". I've tried adding "Authorization: OAuth" to my headers but to no avail (get an error that authorization type is not recognized).
Any advice? I need a secure way to send the oauth token to Google such that my security software won't complain about a security hole in my program ...
Thanks!

To answer your question directly, even though security is irrelevant as you are using HTTPS, you cannot POST to Google to get a list of contacts. Google requires you use Get.
The proper formatting for authorization (Because you can still use a Get and not pass the oauth_token as a query string is to use an HTTP Header formatted:
Authorization: Bearer 1/fFBGRNJru1FQd44AzqT3Zg

Getting bearer token for Discord API

Im trying to get a list of all channels in my discord server using the discord api. However im getting a 401 no access in my api client, probably because I have the wrong api key, but I have no clue how to get a working key. Below you see my api request.
I read in the docs of discord that I need a oAuth2 token, but I just can't seem to figure how to get that token..
Thanks for the replies,
Boudewijn Bout
To make a request to the Discord API you must include a token in the headers:
Authorization: TOKEN.
To get a valid token open DevTools (press F12), go to the network tab, and send a random message to your friend or server. Then you will see that a new row appeared in the network tab. Click on that row then go to its headers and find the authorization header, the value of that header is token. If you have any questions about the Discord API feel free to DM me on Discord - Koll Potato#2437.

Eloqua OAuth2 authentication get token URL inaccessible

I want to use OAuth2 authentication in my application for calling Eloqua APIs using access token.
I'm following instructions given in the link http://docs.oracle.com/cloud/latest/marketingcs_gs/OMCAB/Developers/GettingStarted/Authentication/authenticate-using-oau… and using Resource Owner Password Credentials grant flow for getting access token.
POST https://login.eloqua.com/auth/oauth2/token
Authorization: Basic Q09NUEFOWVhcdXNlcjE6cGFzc3dvcmQxMjM=
{
"grant_type":"password",
"scope":"full",
"username":"testsite\\testuser",
"password":"user123"
}
But I'm getting exception "java.net.ConnectException: Connection timed out: connect" while calling get token endpoint https://login.eloqua.com/auth/oauth2/token from java code.
I tried the endpoint using browser but getting similar error. Also tried accessing the endpoint using REST client but again same connection error.
I'm unable to understand that why the endpoint is giving connection timeout exception. I also tried increasing timeout but same error.
Please guide me as I'm stuck.
Is there any other endpoint for getting Eloqua access token?
Below is a POSTMAN Screenshot in case it helps.
Also written out in case someday that screenshot isn't there. Don't use built in Auth in POSTMAN since you need to base64 encode the clientid:clientsecret with the : in the middle. These values are provided when you created an App in Eloqua.
Be sure to include the content type as application/json and the Authorization. Use a double backslash in the Json for the username in between the site and username (clientsite\\username).
JSON body should look like this:
{"grant_type":"password","username":"clientsite\\username","password":"password"}
Make sure you are doing a POST to login.eloqua.com/auth/oauth2/token
From the docs:
POST https://login.eloqua.com/auth/oauth2/token
Authorization: Basic Q09NUEFOWVhcdXNlcjE6cGFzc3dvcmQxMjM=
{
"grant_type":"authorization_code",
"code":"SplxlOBeZQQYbYS6WxSbIA",
"redirect_uri":"https://client.example.com/cb"
}
From your request, it looks like you are missing the redirect_uri and the code.
Try using the body contract from the docs: http://docs.oracle.com/cloud/latest/marketingcs_gs/OMCAB/index.html#Developers/GettingStarted/Authentication/authenticate-using-oauth.htm

Twitter request token OAuth 401 error

Trying to add twitter login using OAuth and it has been a nightmare to get the first step of requesting the token, which results in 401 error as always.
I used twitter's Test OAuth tool to compare the http request that my scala server sends.Curl request works while my server request fails. Pasting them below for comparison.
Curl Request
curl --request 'POST' 'https://api.twitter.com/oauth/request_token' --data 'oauth_callback=http%3A%2F%2F0.0.0.0%3A8081%2Fweb' --header 'Authorization: OAuth oauth_consumer_key="wRflKWWomJ9jKeK8wbTk0Jck3", oauth_nonce="46ef029600fcc2a6cbe068eb9711401c", oauth_signature="3ptB%2B6%2Fv9QYGgyQjO9DhuD7pmzA%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1422879905", oauth_version="1.0"' --verbose
Scala server Request
HttpRequest(POST,https://api.twitter.com/oauth/request_token,List(Authorization: OAuth oauth_consumer_key="wRflKWWomJ9jKeK8wbTk0Jck3", oauth_nonce="70449464359328", oauth_signature="yEni23tuzEveIMtDm7%2F8N2anU%2FM%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1422879900", oauth_version="1.0"),HttpEntity(application/x-www-form-urlencoded,oauth_callback=http%3A%2F%2F0.0.0.0%3A8081%2Fweb),HTTP/1.1)
Things I tried:
Made sure timestamp is within 5 minutes
Made sure "Allow this
application to be used to Sign in with Twitter" is set in twitter
settings.
Callback url is set - http://0.0.0.0:8081/web (even tried
proxy names for localhost by changing ip table)
Tried generating request token using Saclaj
Used custom OAuth signature request primarily using OAuth.scala
This 401 twitter request token seems to be a recurring theme for many folks, complicated by various failure points. Any help is much appreciated.
For anyone else facing this issue, I am listing down few things that you could benefit from.
After excruciating attempts of permutations and combinations,
oauth_token had to be a part of the signature (even if its value is
empty string). I am not sure if it is mentioned anywhere and particularly ironic that you had to remove access token and secret while using Twitter's OAuth testing tool (for the Curl command to work properly which took some bloody lot of time to figure out.)
It is good to validate your basestring - Tool
Validating if your signature process is correct - Check point (f)
Another possible scenario
In my Twitter client app settings screen, I set an option "Enable Callback Locking (It is recommended to enable callback locking to ensure apps cannot overwrite the callback url)" and this caused me getting 401 unauthorized error on trying to get request token.

Google API - request for token from Oauth2 returns “invalid_request” with HTTP code 400

I know same question has been asked many times but even after following each and every post as well trying various suggestions, I am still facing invalid_request error.
I am able to get code successfully from Google API and when I am trying to access accessToken , I am getting this error and HTTP code being sent from Google API is 400.
I have already tried and compared my data with oauthplayground and seems everything is same
Following data is being sent from my Application to Google API
https://accounts.google.com/o/oauth2/auth?
scope=openid+profile+email
&response_type=code
&redirect_uri=http%3A%2F%2Fsavealifetoday.org%2Fblood_donors%2FoAuthCallBackAction%3Fservice_provider_name%3D
&approval_prompt=force
&client_id=193214746340-ea0nq5alpst82n2fno13s9j21pn4f4pf.apps.googleusercontent.com
Access Token URL
https://accounts.google.com/o/oauth2/token?
scope=openid+profile+email
&client_secret=***********
&grant_type=authorization_code
&redirect_uri=http%3A%2F%2Fsavealifetoday.org%2Fblood_donors%2FoAuthCallBackAction%3Fservice_provider_name%3D
&code=4%2F8veoAnihzkao58oWvZaRShn5nhYg.0to7Or-lHPwRXE-sT2ZLcbTblHXFhgI
&client_id=193214746340-ea0nq5alpst82n2fno13s9j21pn4f4pf.apps.googleusercontent.com
But When Application is trying to fetch data over the network, I am getting exception
SEVERE: Error while fetching access token for Google..
OAuthProblemException{error='invalid_request', description='null', uri='null', state='null', scope='null', redirectUri='null', responseStatus=0, parameters={}}
I am using URLConnectionClient to establish network connection
Go through the OAuth flow using the OAuth playground https://developers.google.com/oauthplayground/.
Then compare what is being sent with your own.
Note that it needs to be an HTTP POST. The code you posted looks like a GET.
Also, your redirect URL looks a little odd. Is that exactly the same URL that you registered in the API console? This is isn't your current error, but will probably become your next one ;-)
It seems that you forgot to send 'state' parameter here (it is mandatory!):
https://accounts.google.com/o/oauth2/auth?
scope=openid+profile+email
&response_type=code
&redirect_uri=http%3A%2F%2Fsavealifetoday.org%2Fblood_donors%2FoAuthCallBackAction%3Fservice_provider_name%3D
&approval_prompt=force
&client_id=193214746340-ea0nq5alpst82n2fno13s9j21pn4f4pf.apps.googleusercontent.com
In Java code you can generate it in a way like this:
String state = new BigInteger(130, new SecureRandom()).toString(32);
So you request should look like this:
https://accounts.google.com/o/oauth2/auth?
scope=openid+profile+email
&response_type=code
&redirect_uri=http%3A%2F%2Fsavealifetoday.org%2Fblood_donors%2FoAuthCallBackAction%3Fservice_provider_name%3D
&approval_prompt=force
&client_id=193214746340-ea0nq5alpst82n2fno13s9j21pn4f4pf.apps.googleusercontent.com
&state= {insert_here_generated_state}
And also I don't know if it is necessary to send a 'scope' parameter in "Access Token URL".

FusionTables Insert works in OAuth2 Playground, but not as HTTPS Post in other systems

Hello kind people of the internet,
We can successfully use the Google Oauth 2.0 Playground to make a simple sql POST insert to a FusionTable, but when attempt the same basic HTTPS POST operation in anything else (from back end system, another browser session, Postman chrome tool, hurl.it, etc, etc), we always get a 403 error:
"message": "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",
I'm puzzled why the error is returned when doing an HTTPS post from other systems (other than OAuth playground)?...as at the time I'm supplying an active Access token (cut-n-pasted Access token from OAuth playground).
The successful-working-good Request block in OAuth 2.0 Playground is below (but the Access token is of course now expired):
POST /fusiontables/v1/query?sql=INSERT INTO 1CqwRGEEn4L0gN66JwGvCR5yOI8miNMVijcp4XlE (Name, Age) VALUES ('Forrest', 57) HTTP/1.1
Host: www.googleapis.com
Content-type: application/json
Authorization: Bearer ya29.AHES6ZRr9CkHptvLaYlba_u6wceIh29urI8FjFp8xMP08AcBm2qpHg
Here's the direct URL that is generated by several different REST based tools I'm attempting to use to simulate the HTTPS request to do a POST sql insert to FusionTables (which again: always generates a 403 error even with an active Access token):
https://www.googleapis.com/fusiontables/v1/query?sql=INSERT%20INTO%201CqwRGEEn4L0gN66JwGvCR5yOI8miNMVijcp4XlE%20(Name,%20Age)%20VALUES%20('Jim',%2057)=&Content-length:=0&Content-type:%20=application/json&Authorization:=%20Bearer%20ya29.AHES6ZRr9CkHptvLaYlba_u6wceIh29urI8FjFp8xMP08AcBm2qpHg
Some other notes:
-In my Google APIs Console, I'm using the "Client ID for web applications".
-I updated the FusionTable properties with the Api console email-address to allow edit capability on the fusiont table used in the above sql (1CqwRGEEn4L0gN66JwGvCR5yOI8miNMVijcp4XlE) Adding the email for edit capability to the FusionTable properties was kindly suggested by Odi for Service accounts on another related post on FusionTables).
Any help in explaining why HTTPS Post works in the OAuth playground for a sql insert to FusionTables, but not anywhere else would surely be appreciated...there must be something I'm missing, as supposedly the OAuth playground was to help illuminate how OAuth works at a detailed level so we could handle in other systems that don't necessarily have a developed OAuth library.
Update 8/23, per the suggested answer...here's a URL syntax that works in POSTMAN and uses both the OAuth API key and an active Access token which was obtained using the OAuth playground (access token is of course fake/expired).
https://www.googleapis.com/fusiontables/v1/query?sql=INSERT%20INTO%201CqwRGEEn4L0gN66JwGvCR5yOI8miNMVijcp4XlE%20(Name,%20Age)%20VALUES%20('Bob',%2031)=&Content-length:=0&Content-type:%20=application/json&key={OAuth API key}&access_token=ya29.AHES6ZST_c2CjdXeIyG8LwkprQMGGfoW45sonX0d1H51234
Try adding your API key to the POST. Even though the message refers to authentication I'm pretty sure it's not OAuth authentication but your API usage that needs to be verified.
