I'm using Ruby starting from the "hello world" example. Hello world works find. I'm trying to get this GET to work:
GET /projects/192372431230306/tasks?opt_fields=id,assignee,due_on,name,notes&limit=10&completed_since=now
It works exactly as expected in the Asana API explorer.
I'm using the same URI in my code:
uri = URI.parse("https://app.asana.com/api/1.0/projects/192372431230306/tasks?opt_fields=id,assignee,due_on,name,notes&limit=10&completed_since=now")
It still returns ID and Name correctly, but it's not what I want.
I can't see why it works in the explorer but not in the GET request. I am using the personal token and the explorer uses OAuth.
My personal token is set correctly before this code. I can create tasks, get projects, get tasks. I just can't more fields in this query like the API explorer.
Added Code:
uri = URI.parse("https://app.asana.com/api/1.0/projects/192372431230306/tasks?opt_fields=id,assignee,due_on,name,notes&limit=10&completed_since=now")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
# set up the request
header = {
"Content-Type" => "application/json"
}
req = Net::HTTP::Get.new(uri.path, header)
req.basic_auth(personal_access_token, '')
res = http.start { |http| http.request(req) }
body = JSON.parse(res.body)
puts "projects: #{body['data']}"
There isn't quite enough code here to know what's wrong. It sounds like your code is working to some degree, but maybe there's something different between using a personal token as opposed to OAuth. According to the Asana API documentation:
Personal Access Tokens should be used similarly to OAuth access tokens when accessing the API, passing them in the Authorization header:
curl -H "Authorization: Bearer ACCESS_TOKEN" https://app.asana.com/api/1.0/users/me
So in addition to the URL, you need to use the correct headers. I'm not sure what HTTP library you use, but here's how I would do it with HTTParty:
require 'uri'
require 'httparty'
uri = URI.parse("https://app.asana.com/api/1.0/projects/192372431230306/tasks?opt_fields=id,assignee,due_on,name,notes&limit=10&completed_since=now")
task = HTTParty.get(uri,
:headers =>
{'Authorization' => "Bearer ${ENV[ACCESS_TOKEN]}"}
).parsed_response
If you put your personal access token in the ACCESS_TOKEN environment variable, that should correctly authenticate you for the request.
Still, it seems like there's something else missing if you can get all the fields. Maybe your personal access token is associated with a different account than your OAuth access token? It might help to check the results of /users/me/ route?
I keep getting an invalid_grant error on trying to get an oAuth token from Google to connect to their contacts api. All the information is correct and I have tripple checked this so kind of stumped.
Does anyone know what may be causing this issue? I have tried setting up a different client id for it but I get the same result, I have tried connecting many different ways including trying the force authentication, but still the same result.
Although this is an old question, it seems like many still encounter it - we spent days on end tracking this down ourselves.
In the OAuth2 spec, "invalid_grant" is sort of a catch-all for all errors related to invalid/expired/revoked tokens (auth grant or refresh token).
For us, the problem was two-fold:
User has actively revoked access to our app
Makes sense, but get this: 12 hours after revocation, Google stops sending the error message in their response:
“error_description” : “Token has been revoked.”
It's rather misleading because you'll assume that the error message is there at all times which is not the case. You can check whether your app still has access at the apps permission page.
User has reset/recovered their Google password
In December 2015, Google changed their default behaviour so that password resets for non-Google Apps users would automatically revoke all the user's apps refresh tokens. On revocation, the error message follows the same rule as the case before, so you'll only get the "error_description" in the first 12 hours. There doesn't seem to be any way of knowing whether the user manually revoked access (intentful) or it happened because of a password reset (side-effect).
Apart from those, there's a myriad of other potential causes that could trigger the error:
Server clock/time is out of sync
Not authorized for offline access
Throttled by Google
Using expired refresh tokens
User has been inactive for 6 months
Use service worker email instead of client ID
Too many access tokens in short time
Client SDK might be outdated
Incorrect/incomplete refresh token
I've written a short article summarizing each item with some debugging guidance to help find the culprit.
I ran into this same problem despite specifying the "offline" access_type in my request as per bonkydog's answer. Long story short I found that the solution described here worked for me:
https://groups.google.com/forum/#!topic/google-analytics-data-export-api/4uNaJtquxCs
In essence, when you add an OAuth2 Client in your Google API's console Google will give you a "Client ID" and an "Email address" (assuming you select "webapp" as your client type). And despite Google's misleading naming conventions, they expect you to send the "Email address" as the value of the client_id parameter when you access their OAuth2 API's.
This applies when calling both of these URL's:
https://accounts.google.com/o/oauth2/auth
https://accounts.google.com/o/oauth2/token
Note that the call to the first URL will succeed if you call it with your "Client ID" instead of your "Email address". However using the code returned from that request will not work when attempting to get a bearer token from the second URL. Instead you will get an 'Error 400' and an "invalid_grant" message.
I ran into this problem when I didn't explicitly request "offline" access when sending the user to the OAuth "Do you want to give this app permission to touch your stuff?" page.
Make sure you specify access_type=offline in your request.
Details here: https://developers.google.com/accounts/docs/OAuth2WebServer#offline
(Also: I think Google added this restriction in late 2011. If you have old tokens from before then, you'll need to send your users to the permission page to authorize offline use.)
If you're testing this out in postman / insomnia and are just trying to get it working, hint: the server auth code (code parameter) is only good once. Meaning if you stuff up any of the other parameters in the request and get back a 400, you'll need to use a new server auth code or you'll just get another 400.
I encountered the same problem. For me, I fixed this by using Email Address (the string that ends with ...#developer.gserviceaccount.com) instead of Client ID for client_id parameter value. The naming set by Google is confusing here.
We tried so many things, and in the end the issue was that the client had turned
"Less Secure App Access" off in their Google Account settings.
To turn this on:
Go to https://myaccount.google.com/ and manage account
Go to the Security tab
Turn Less secure app access on
I hope this saves someone some time!
My issue was that I used this URL:
https://accounts.google.com/o/oauth2/token
When I should have used this URL:
https://www.googleapis.com/oauth2/v4/token
This was testing a service account which wanted offline access to the Storage engine.
This is a silly answer, but the problem for me was that I failed to realize I already had been issued an active oAuth token for my google user which I failed to store. The solution in this case is to go to the api console and reset the client secret.
There are numerous other answers on SO to this effect for example
Reset Client Secret OAuth2 - Do clients need to re-grant access?
Using a Android clientId (no client_secret) I was getting the following error response:
{
"error": "invalid_grant",
"error_description": "Missing code verifier."
}
I cannot find any documentation for the field 'code_verifier' but I discovered if you set it to equal values in both the authorization and token requests it will remove this error. I'm not sure what the intended value should be or if it should be secure. It has some minimum length (16? characters) but I found setting to null also works.
I am using AppAuth for the authorization request in my Android client which has a setCodeVerifier() function.
AuthorizationRequest authRequest = new AuthorizationRequest.Builder(
serviceConfiguration,
provider.getClientId(),
ResponseTypeValues.CODE,
provider.getRedirectUri()
)
.setScope(provider.getScope())
.setCodeVerifier(null)
.build();
Here is an example token request in node:
request.post(
'https://www.googleapis.com/oauth2/v4/token',
{ form: {
'code': '4/xxxxxxxxxxxxxxxxxxxx',
'code_verifier': null,
'client_id': 'xxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com',
'client_secret': null,
'redirect_uri': 'com.domain.app:/oauth2redirect',
'grant_type': 'authorization_code'
} },
function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log('Success!');
} else {
console.log(response.statusCode + ' ' + error);
}
console.log(body);
}
);
I tested and this works with both https://www.googleapis.com/oauth2/v4/token and https://accounts.google.com/o/oauth2/token.
If you are using GoogleAuthorizationCodeTokenRequest instead:
final GoogleAuthorizationCodeTokenRequest req = new GoogleAuthorizationCodeTokenRequest(
TRANSPORT,
JSON_FACTORY,
getClientId(),
getClientSecret(),
code,
redirectUrl
);
req.set("code_verifier", null);
GoogleTokenResponse response = req.execute();
There are two major reasons for invalid_grant error which you have to take care prior to the POST request for Refresh Token and Access Token.
Request header must contain "content-type: application/x-www-form-urlencoded"
Your request payload should be url encoded Form Data, don't send as json object.
RFC 6749 OAuth 2.0 defined invalid_grant as:
The provided authorization grant (e.g., authorization code, resource owner credentials) or refresh token is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.
I found another good article, here you will find many other reasons for this error.
https://blog.timekit.io/google-oauth-invalid-grant-nightmare-and-how-to-fix-it-9f4efaf1da35
Solved by removing all Authorized redirect URIs in Google console for the project.
I use server side flow when you use 'postmessage' as redirect URI
I had the same error message 'invalid_grant' and it was because the
authResult['code']
send from client side javascript was not received correctly on the server.
Try to output it back from the server to see if it is correct and not an empty string.
Try change your url for requst to
https://www.googleapis.com/oauth2/v4/token
You might have to remove a stale/invalid OAuth response.
Credit: node.js google oauth2 sample stopped working invalid_grant
Note: An OAuth response will also become invalid if the password used in the initial authorization has been changed.
If in a bash environment, you can use the following to remove the stale response:
rm /Users/<username>/.credentials/<authorization.json>
The code you obtain in the URL after user consent has a very short expiry. Please obtain the code again and attempt to get access token within seconds (you have to hurry) and it should work. I can't find out the expiry period of code but it's literally very short.
In my case it was a callback URL that was different from the original request.
So, callback URL should be the same for auth request and code exchange.
if you are using scribe library, for example to set up the offline mode, like bonkydog suggested.
here is the code:
OAuthService service = new ServiceBuilder().provider(Google2Api.class).apiKey(clientId).apiSecret(apiSecret)
.callback(callbackUrl).scope(SCOPE).offline(true)
.build();
https://github.com/codolutions/scribe-java/
I my case I just didn't read the documentation properly because I was trying to do const { tokens } = await oauth2Client.getToken(accessToken);
every time to get an authorized client instance but for the subsequent requests you only need to include the refresh_token you store after the first user auth.
oauth2Client.setCredentials({
refresh_token: `STORED_REFRESH_TOKEN`
});
This can happen if your redirect_url is not the same as the one you have when creating the token on Google Gloud. So make sure it's correct
in this site
console.developers.google.com
this console board select your project input the oath url.
the oauth callback url will redirect when the oauth success
After considering and trying all of the other ways here, here's how I solved the issue in nodejs with the googleapis module in conjunction with the request module, which I used to fetch the tokens instead of the provided getToken() method:
const request = require('request');
//SETUP GOOGLE AUTH
var google = require('googleapis');
const oAuthConfigs = rootRequire('config/oAuthConfig')
const googleOAuthConfigs = oAuthConfigs.google
//for google OAuth: https://github.com/google/google-api-nodejs-client
var OAuth2 = google.auth.OAuth2;
var googleOAuth2Client = new OAuth2(
process.env.GOOGLE_OAUTH_CLIENT_ID || googleOAuthConfigs.clientId,
process.env.GOOGLE_OAUTH_CLIENT_SECRET || googleOAuthConfigs.clientSecret,
process.env.GOOGLE_OAUTH_CLIENT_REDIRECT_URL || googleOAuthConfigs.callbackUrl);
/* generate a url that asks permissions for Google+ and Google Calendar scopes
https://developers.google.com/identity/protocols/googlescopes#monitoringv3*/
var googleOAuth2ClientScopes = [
'https://www.googleapis.com/auth/plus.me',
'https://www.googleapis.com/auth/userinfo.email'
];
var googleOAuth2ClientRedirectURL = process.env.GOOGLE_OAUTH_CLIENT_REDIRECT_URL || googleOAuthConfigs.callbackUrl;
var googleOAuth2ClientAuthUrl = googleOAuth2Client.generateAuthUrl({
access_type: 'offline', // 'online' (default) or 'offline' (gets refresh_token)
scope: googleOAuth2ClientScopes // If you only need one scope you can pass it as string
});
//AFTER SETUP, THE FOLLOWING IS FOR OBTAINING TOKENS FROM THE AUTHCODE
const ci = process.env.GOOGLE_OAUTH_CLIENT_ID || googleOAuthConfigs.clientId
const cs = process.env.GOOGLE_OAUTH_CLIENT_SECRET || googleOAuthConfigs.clientSecret
const ru = process.env.GOOGLE_OAUTH_CLIENT_REDIRECT_URL || googleOAuthConfigs.callbackUrl
var oauth2Client = new OAuth2(ci, cs, ru);
var hostUrl = "https://www.googleapis.com";
hostUrl += '/oauth2/v4/token?code=' + authCode + '&client_id=' + ci + '&client_secret=' + cs + '&redirect_uri=' + ru + '&grant_type=authorization_code',
request.post({url: hostUrl}, function optionalCallback(err, httpResponse, data) {
// Now tokens contains an access_token and an optional refresh_token. Save them.
if(!err) {
//SUCCESS! We got the tokens
const tokens = JSON.parse(data)
oauth2Client.setCredentials(tokens);
//AUTHENTICATED PROCEED AS DESIRED.
googlePlus.people.get({ userId: 'me', auth: oauth2Client }, function(err, response) {
// handle err and response
if(!err) {
res.status(200).json(response);
} else {
console.error("/google/exchange 1", err.message);
handleError(res, err.message, "Failed to retrieve google person");
}
});
} else {
console.log("/google/exchange 2", err.message);
handleError(res, err.message, "Failed to get access tokens", err.code);
}
});
I simply use request to make the api request via HTTP as described here:
https://developers.google.com/identity/protocols/OAuth2WebServer#offline
POST /oauth2/v4/token HTTP/1.1
Host: www.googleapis.com
Content-Type: application/x-www-form-urlencoded
code=4/P7q7W91a-oMsCeLvIaQm6bTrgtp7&
client_id=8819981768.apps.googleusercontent.com&
client_secret={client_secret}&
redirect_uri=https://oauth2.example.com/code&
grant_type=authorization_code
For future folks... I read many articles and blogs but had luck with solution below...
GoogleTokenResponse tokenResponse =
new GoogleAuthorizationCodeTokenRequest(
new NetHttpTransport(),
JacksonFactory.getDefaultInstance(),
"https://www.googleapis.com/oauth2/v4/token",
clientId,
clientSecret,
authCode,
"") //Redirect Url
.setScopes(scopes)
.setGrantType("authorization_code")
.execute();
This blog depicts different cases in which "invalid_grant" error comes.
Enjoy!!!
for me I had to make sure that the redirect_uri is an exact match to the one in the developer console Authorised redirect URIs, that fixed it for me, I was able to debug and know what exactly was the issue after switching from
https://accounts.google.com/o/oauth2/token to https://www.googleapis.com/oauth2/v4/token
I got a proper error:
{"error": "redirect_uri_mismatch", "error_description": "Bad Request"}
I had this problem after enabling a new service API on the Google console and trying to use the previously made credentials.
To fix the problem, I had to go back to the credential page, clicking on the credential name, and clicking "Save" again. After that, I could authenticate just fine.
In my case, the issue was in my code. Mistakenly I've tried to initiate client 2 times with the same tokens. If none of the answers above helped make sure you do not generate 2 instances of the client.
My code before the fix:
def gc_service
oauth_client = Signet::OAuth2::Client.new(client_options)
oauth_client.code = params[:code]
response = oauth_client.fetch_access_token!
session[:authorization] = response
oauth_client.update!(session[:authorization])
gc_service = Google::Apis::CalendarV3::CalendarService.new
gc_service.authorization = oauth_client
gc_service
end
primary_calendar_id = gc_service.list_calendar_lists.items.select(&:primary).first.id
gc_service.insert_acl(primary_calendar_id, acl_rule_object, send_notifications: false)
as soon as I change it to (use only one instance):
#gc_service = gc_service
primary_calendar_id = #gc_service.list_calendar_lists.items.select(&:primary).first.id
#gc_service.insert_acl(primary_calendar_id, acl_rule_object, send_notifications: false)
it fixed my issues with grant type.
For me the issues was I had multiple clients in my project and I am pretty sure this is perfectly alright, but I deleted all the client for that project and created a new one and all started working for me ( Got this idea fro WP_SMTP plugin help support forum) I am not able to find out that link for reference
If you are sanitizing user input (For example, $_GET["code"] in php) Make sure you don't accidentally replace something in the code.
The regex I am using is now /[^A-Za-z0-9\/-]/
Look at this https://dev.to/risafj/beginner-s-guide-to-oauth-understanding-access-tokens-and-authorization-codes-2988
First you need an access_token:
$code = $_GET['code'];
$clientid = "xxxxxxx.apps.googleusercontent.com";
$clientsecret = "xxxxxxxxxxxxxxxxxxxxx";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/oauth2/v4/token");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "client_id=".urlencode($clientid)."&client_secret=".urlencode($clientsecret)."&code=".urlencode($code)."&grant_type=authorization_code&redirect_uri=". urlencode("https://yourdomain.com"));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
curl_close ($ch);
$server_output = json_decode($server_output);
$access_token = $server_output->access_token;
$refresh_token = $server_output->refresh_token;
$expires_in = $server_output->expires_in;
Safe the Access Token and the Refresh Token and the expire_in, in a Database. The Access Token expires after $expires_in seconds. Than you need to grab a new Access Token (and safe it in the Database) with the following Request:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/oauth2/v4/token");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "client_id=".urlencode($clientid)."&client_secret=".urlencode($clientsecret)."&refresh_token=".urlencode($refresh_token)."&grant_type=refresh_token");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
curl_close ($ch);
$server_output = json_decode($server_output);
$access_token = $server_output->access_token;
$expires_in = $server_output->expires_in;
Bear in Mind to add the redirect_uri Domain to your Domains in your Google Console: https://console.cloud.google.com/apis/credentials in the Tab "OAuth 2.0-Client-IDs". There you find also your Client-ID and Client-Secret.
There is a undocumented timeout between when you first redirect the user to the google authentication page (and get back a code), and when you take the returned code and post it to the token url. It works fine for me with the actual google supplied client_id as opposed to an "undocumented email address". I just needed to start the process again.
For me, this was caused by subsequent getToken calls with the same code.
Namely, in NestJS my callback endpoint was decorated with #UseGuards(AuthGuard('google')) and I tried to call getToken in the callback.
