I have an existing Xero app that's worked well for over a year that uses OAuth2 to connect a small number of organisations to one of three Web Apps: developer, sandbox, and production. Sandbox and production are working well. However, yesterday I started to create a new instance of the developer app and am unable to complete the first step. My app calls the following URL:
https://login.xero.com/identity/connect/authorize?response_type=code&client_id=069BFC79B7REDACTED&redirect_uri=https%3A%2F%2Fdev.addressredacted.ngrok.io%2Fcotrustee%2Fxero&scope=offline_access+accounting.transactions+accounting.settings+accounting.journals.read
This URL has the same form that has worked for over a year, just with a new client_id, but now I keep getting this error:
Access Denied
You don't have permission to access "http://authorize.xero.com/?" on this server.
Reference #18.d2fdda17.1671639885.53ec38b
I expect to be redirected to a Xero login page instead.
From the Ref# that you received, it looks like it has hit the Akamai WAF. Unfortunately the code has expired (it only has a lifetime of 24 hours) thus we are unable to check why it was blocked.
Can you contact Xero API Support - api at xero dot com - with a newer reference so we can further investigate?
I don't think this issue is specific to PyDrive, but rather Google OAuth. However, some of the solutions I've seen on stackoverflow don't seem to be transferable over to my PyDrive application, which is just a python script to upload files programmatically to a shared drive. It worked fine 2 months ago but I tried to rerun it today and it's not working. Here is the error I'm getting:
Authorisation Error
Error 400: invalid_request
You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure.
You can let the app developer know that this app doesn't comply with one or more Google validation rules.

redirect_uri: urn:ietf:wg:oauth:2.0:oob
I am using a web application OAuth 2.0 Client ID creds on GCP. All secrets are stored in a local client_secrets.json file.
I run my script, it sends a message to the console that says
Go to the following link in your browser:
https://accounts.google.com/o/oauth2/auth?client_id=blahblahblah.apps.googleusercontent.com&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive&access_type=offline&response_type=code
Enter verification code:
How it used to work: After I click the link above, it returns a code I paste into the console and then its authenticated. FYI: I plan on running this 24/7 on a remote server.
Now: I click the link above and get the error I posted above. I've tried to change the redirect uri to 127.0.0.1 and it does allow me to auth, then I get a code in my URL, but once I copy that and paste it into the console, I get more errors.
Anyone know the solution for this?
I get the following error on my Google cloud account if I try to authenticate via oauth2.
That’s an error.
Error: deleted_client
The OAuth client was deleted.
It used to work for over 2 years now. I did not have changed anything.
How can I repair this?
It seems that your OAuth client got deleted from your console, there's a similar question regarding this issue in the following link. You can check that by heading to the APIs & Services menu, under the Credentials topic.
Quoting the provided solution there:
You need to restore (if possible) or re-create it.
Dashboard -> Enable APIs and get credentials like keys -> Credentials -> New Credentials -> OAuth Client ID
Add the new client id and Reversed Client id to GoogleService-Info.plist
Finally add com.googleusercontent.{apps.YOUR_CLIENT_ID} to URLSchemes
Currently Google Assitant includes an easy way to request non-identifiable information about the user and a detailed flow to authenticate the user on a third party service through OAuth2. What about if all I need is have the user authenticate on Google itself? I tried filling in the account linking flow using Google OAuth2 information, but that seems not to work. If that last thing is supposed to work fluently than that would be enough of an answer.
Context: Users already authenticate only with Google on a related webpage. All I need is to link this already authenticated account with the less-authenticated account on Google Assistant.
Update, 25 Oct 2018:
As of 13 September 2018, there is now a much simpler way to access the user's account if your project uses Google Sign-In. Google Sign-In for Assistant will give you an ID Token with information about the user, including their Google ID, with their permission. This permission can be granted just using voice and is fairly streamlined.
You can combine this with a web- or app-based Google Sign-In to get their permission to access OAuth scopes if you need to access Google's APIs.
Update, 25 Oct 2017:
As of around 4 Oct or 7 Oct, Google has updated their policy (again) to restore language restricting OAuth endpoints that are valid. The terms now include
When implementing account linking using OAuth, you must own your OAuth endpoint
and it appears (from the comments below) that they now check for the Google endpoints to prevent this method from working.
At this point, the only thing you can do is setup your own OAuth2 server.
Original Post:
Broadly speaking, the auth tasks you need to do are in four parts:
Configure your project (in the cloud console) so that the Calendar API is enabled and that the OAuth2 client is correctly configured.
Configure the Action for account linking in the action console.
Configure the Actions on Google Integration for your API.AI Agent to indicate that sign-in is required.
When API.AI calls your webhook to fulfill an Intent, it will include an auth token as part of the JSON. You can use this token to make calls to the Google APIs you need.
Configure Cloud Project
You need to configure your cloud project so that it has access to the Google APIs you need and setup the OAuth2 Client ID, Secret, and Redirect URI.
Go to https://console.cloud.google.com/apis/dashboard and make sure you have the project you're working with selected. Then make sure you have the APIs you need enabled.
Select the "Credentials" menu on the left. You should see something like this:
Select "Create credentials" and then "OAuth client ID"
Select that this is for a "Web application" (it is... kinda...)
Enter a name. In the screen shot below, I used "Action client" so I remember that this is actually for Actions on Google.
In the "Authorized Redirect URIs" section, you need to include a URI of the form https://oauth-redirect.googleusercontent.com/r/your-project-id replacing the "your-project-id" part with... your project ID in the Cloud Console. At this point, the screen should look something like this:
Click the "Create" button and you'll get a screen with your Client ID and Secret. You can get a copy of these now, but you can also get them later.
Click on "Ok" and you'll be taken back to the "Credentials" screen with the new Client ID added. You can click the pencil icon if you ever need to get the ID and Secret again (or reset the secret if it has been compromised).
Configure the Action Console
Once we have OAuth setup for the project, we need to tell Actions that this is what we'll be using to authenticate and authorize the user.
Go to https://console.actions.google.com/ and select the project you'll be working with.
In the Overview, make your way through any configuration necessary until you can get to Step 4, "Account Linking". This may require you to set names and icons - you can go back later if needed to correct these.
Select the Grant Type of "Authorization Code" and click Next.
In the Client Information section, enter the Client ID and Client Secret from when you created the credentials in the Cloud Console. (If you forget, go to the Cloud Console API Credentials section and click on the pencil.)
For the Authorization URL, enter https://accounts.google.com/o/oauth2/v2/auth
For the Token URL, enter https://www.googleapis.com/oauth2/v4/token
Click Next
You now configure your client for the scopes that you're requesting. Unlike most other places you enter scopes - you need to have one per line. Then click Next.
You need to enter testing instructions. Before you submit your Action, these instructions should contain a test account and password that the review team can use to evaluate it. But you can just put something there while you're testing and then hit the Save button.
Configure API.AI
Over in API.AI, you need to indicate that the user needs to sign-in to use the Action.
Go to https://console.api.ai/ and select the project you're working with.
Select "Integrations" and then "Actions on Google". Turn it on if you haven't already.
Click the "Sign in required for welcome intent" checkbox.
Handle things in your webhook
After all that setup, handling things in your webhook is fairly straightforward! You can get an OAuth Access Token in one of two ways:
If you're using the JavaScript library, calling app.getUser().authToken
If you're looking at the JSON body, it is in originalRequest.data.user.accessToken
You'll use this Access Token to make calls against Google's API endpoints using methods defined elsewhere.
You don't need a Refresh Token - the Assistant should hand you a valid Access Token unless the user has revoked access.
After contacting Google the current situation seems to be that you should set up your own OAuth2 server, and then on the login screen of your OAuth2 server you should start the Google OAuth2 flow.
you have to have your own endpoint with Google Oauth2 - it is correct that you can't use Google Oauth itself as a provider. To use the Google OAuth service, you can use a "sign in with Google" button in your own endpoint instead.
Source: Contacting Google Actions on Google Support
Kind of speechless right now... as this seems to be a huge oversight on Google's part.
I am able to make it work after a long time.
We have to enable the webhook first and we can see how to enable the webhook in the dialog flow fulfillment docs
If we are going to use Google Assistant, then we have to enable the Google Assistant Integration in the integrations first.
Then follow the steps mentioned below for the Account Linking in actions on google:-
Go to google cloud console -> APIsand Services -> Credentials -> OAuth 2.0 client IDs -> Web client -> Note the client ID, client secret from there
-> Download JSON - from json note down the project id, auth_uri, token_uri
-> Authorised Redirect URIs -> White list our app's URL -> in this URL fixed part is https://oauth-redirect.googleusercontent.com/r/ and append the project id in the URL
-> Save the changes
Actions on Google -> Account linking setup
1. Grant type = Authorisation code
2. Client info
1. Fill up client id,client secrtet, auth_uri, token_uri
2. Enter the auth uri as https://www.googleapis.com/auth and token_uri as https://www.googleapis.com/token
3. Save and run
4. It will show an error while running on the google assistant, but dont worry
5. Come back to the account linking section in the assistant settings and enter auth_uri as https://accounts.google.com/o/oauth2/auth
and token_uri as https://accounts.google.com/o/oauth2/token
6. Put the scopes as https://www.googleapis.com/auth/userinfo.profile and https://www.googleapis.com/auth/userinfo.email
and weare good to go.
7. Save the changes.
In the hosting server logs, we can see the access token value and through access token, we can get the details regarding the email address.
Append the access token to this link "https://www.googleapis.com/oauth2/v1/userinfo?access_token=" and we can get the required details in the resulting json page.
accessToken = req.get("originalRequest").get("data").get("user").get("accessToken")
r = requests.get(link)
print("Email Id= " + r.json()["email"])
print("Name= " + r.json()["name"])
You need to implement the Oauth protocol with whatever Google Assistant app you are developing. Let me be a bit more clear:
The user is on the assistant, you need to link him to any data
you have on your App side
The access to the data you have about
your user is protected by an access token
Google then needs to
ask you for this token to have access to this resource
When
google has the token it can send it to the app so it validates every
requests to get the resource.
This is why you need to implement your own oauth server (Honestly it is just two more endpoints in your application): the identity is checked on google's side, but the link between the user and the resource to access can only be known by you.
The process above is valid, you just need to specify your own token endpoint and your own auth endpoint.
Note that if you only want to check that the user is logged in into google and get his email, you just need to implement the streamlined identity flow that does not require the /auth endpoint (Automatically Sign Up Users with Streamlined Identity Flows)
That beeing said I implemented the flow but get the same error :
expected_inputs[0].possible_intents[0]: Transactions/Identity API must be enabled before using.
Given the following ruby code:
consumer = OAuth::Consumer.new(consumer_key, consumer_secret, {
site: "https://www.googleapis.com"
})
resp = consumer.request(:put, "/appsmarket/v2/upgradableApp/#{listingId}/#{cwsId}/#{domain}")
puts resp.code+"\n"
puts resp.body
the UpgradeableApp API keeps giving "Invalid OAuth consumer key" error. The consumer key (in the format XXXXXXXXXXXX.apps.googleusercontent.com) was copied directly from the legacy marketplace listing as described in the docs.
I've:
verified the system time is correct and synchronized via ntp.
tried including xoauth_requestor_id
tried generating the request myself via curl (using this to generate the oauth signature)
tried enabling "Google Apps Marketplace API" under "Register for additional APIs" on the legacy marketplace listing
Is anybody else experiencing this? Thoughts on other things I can try?
UPDATE Sep 10 2014: I got confirmation from Google that this was an issue on their end for which a fix was applied. I've since been able to successfully use the ruby code above to do a migration.
