@chilly-king-10285 what does this error mean when im trying to exchange code for token in oauth2: "Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method). The OAuth 2.0 Client supports client authentication method 'client_secret_basic', but method 'client_secret_post' was requested. You must configure the OAuth 2.0 client's 'token_endpoint_auth_method' value to accept 'client_secret_post'."
c
A message from kapa.ai
The error message you're seeing is indicating that the OAuth 2.0 client you're using is configured to use the 
client_secret_basic
authentication method, but the 
client_secret_post
method was requested instead. In the 
client_secret_basic
method, the OAuth 2.0 Client ID and secret are sent in the HTTP Header (
Authorization: basic ....
). On the other hand, in the 
client_secret_post
method, the OAuth 2.0 Client ID and secret are sent in the POST body (
Content-Type: application/x-www-form-urlencoded
). To resolve this issue, you need to configure the OAuth 2.0 client's 
token_endpoint_auth_method
value to accept 
client_secret_post
. You can do this in the CLI with the 
--token-endpoint-auth-method
flag. Here is an example of how you can check which method is allowed:
Copy code
bash ory get oauth2-client {client.id}      {    // ...    "token_endpoint_auth_method": "client_secret_basic",    // ...   }
In this example, the client is allowed to authorize using HTTP Basic Authorization. If you want to allow a client to perform the POST authorization scheme, you must set 
"token_endpoint_auth_method": "client_secret_post"
. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/hydra/debug/token-endpoint-auth-method).

@chilly-king-10285 i dont really want to change this, can you show me a code example how would i go about exchanging code for a token in 
client_secret_basic
so i dont need to change the config?
c
A message from kapa.ai
Sure, here's an example of how you can exchange an authorization code for a token using the 
client_secret_basic
authentication method. This method involves sending the client ID and client secret as part of the Authorization header in an HTTP request.
Copy code
javascript const clientID = "the-client-id"   const clientSecret = "the-secret-id"   const basicAuth = bas64_encode(url_encode(clientID) + ":" + url_encode(clientSecret))      const requestOptions = {    method: "POST",    headers: {    Authorization: "Basic " + basicAuth,    "Content-Type": "application/x-www-form-urlencoded",    },    body: "grant_type=authorization_code&code=your_authorization_code",   }      fetch("<https://your-project.projects.oryapis.com/oauth2/token>", requestOptions)    .then((response) => response.json())    .then((data) => console.log(data))
In this code, replace 
"the-client-id"
and 
"the-secret-id"
with your actual client ID and secret. Also, replace 
"your_authorization_code"
with the actual authorization code you received from the authorization server. This code sends a POST request to the token endpoint with the client ID and secret in the Authorization header. The body of the request includes the grant type (
authorization_code
) and the authorization code. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/oauth2-oidc/client-credentials#basic-authentication).
m
@chilly-king-10285 where is the bas64_encode and url_encode imported from?
c
A message from kapa.ai
I apologize for the confusion. The 
bas64_encode
and 
url_encode
functions are not standard JavaScript functions and were used in the example for illustrative purposes. In JavaScript, you can use the built-in 
btoa
function for base64 encoding and 
encodeURIComponent
for URL encoding. Here's how you can modify the code:
Copy code
javascript const clientID = encodeURIComponent("the-client-id"); const clientSecret = encodeURIComponent("the-secret-id"); const basicAuth = btoa(clientID + ":" + clientSecret);  const requestOptions = {   method: "POST",   headers: {     Authorization: "Basic " + basicAuth,     "Content-Type": "application/x-www-form-urlencoded",   },   body: "grant_type=authorization_code&code=your_authorization_code", };  fetch("<https://your-project.projects.oryapis.com/oauth2/token>", requestOptions)   .then((response) => response.json())   .then((data) => console.log(data));
In this code, 
encodeURIComponent
is used to URL encode the client ID and secret, and 
btoa
is used to base64 encode the resulting string. Please replace 
"the-client-id"
, 
"the-secret-id"
, and 
"your_authorization_code"
with your actual values.

@chilly-king-10285 got this error when trying your code: 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. not_found
c
A message from kapa.ai
The error message you're seeing typically indicates that the authorization code you're using to exchange for an access token is invalid. This could be due to several reasons: 1. The authorization code has expired. Authorization codes are short-lived and typically expire after a few minutes. 2. The authorization code was already used. Authorization codes are single-use. Once you've used it to get an access token, you can't use it again. 3. The redirection URI in your token request doesn't match the one used in the authorization request. The redirection URI must be exactly the same in both requests. 4. The authorization code was issued to a different client. Make sure you're using the correct client ID and secret. Here's how you can check your OAuth 2.0 client configuration:
Copy code
bash ory get oauth2-client {client.id}}
The result shows you the whole client (excluding its secret). Check that the values are correct, especially the 
redirect_uris
field. The redirect URI in your token request must match one of these URIs exactly. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/hydra/debug#authorization-code-is-invalid).
m
@chilly-king-10285 the authorization code should be the "login_challenge" is that correct?
c
A message from kapa.ai
No, the 
login_challenge
and the authorization code are not the same thing. The 
login_challenge
is a parameter that Ory generates and includes in the initial authentication request to your application's login endpoint. It's used to fetch important information about the authentication request and to complete the login flow. On the other hand, the authorization code is a value that the authorization server (Ory in this case) generates and returns to your application after the user successfully authenticates. Your application then exchanges this authorization code for an access token. In the context of Ory, after the user logs in, your application should call the 
/oauth2/auth/requests/login/accept
endpoint with the 
login_challenge
to indicate that the login was successful. Ory will then redirect the user back to your application with an authorization code. Your application should then exchange this authorization code for an access token. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/oauth2-oidc/custom-login-consent/flow#login).
m
@chilly-king-10285 that is correct, ory does give me the redirect link when i accept login, could you give me an example of what part of the redirect url is the authorization code?
c
A message from kapa.ai
Sure, when Ory redirects the user back to your application after a successful login, it includes the authorization code as a query parameter in the redirect URL. Here's an example of what the redirect URL might look like:
Copy code
<https://myapp.com/callback?code=AUTHORIZATION_CODE&state=12345>
In this URL, 
AUTHORIZATION_CODE
is the authorization code that Ory generated. The 
state
parameter is a value that your application should have generated and included in the initial authorization request to protect against cross-site request forgery (CSRF) attacks. To extract the authorization code from the URL in a JavaScript application, you can use the 
URLSearchParams
interface:
Copy code
javascript const urlParams = new URLSearchParams(window.location.search); const authorizationCode = urlParams.get('code');
In this code, 
window.location.search
is the query string part of the URL (including the leading 
?
character), and 
urlParams.get('code')
gets the value of the 
code
parameter. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/oauth2-oidc/authorization-code-flow#step-3-exchange-the-authorization-code-for-an-access-token).

c
A message from kapa.ai
The URL you provided appears to be the initial authorization request that your application sends to Ory to start the OAuth 2.0 authorization code flow. This is not the redirect URL that Ory sends back to your application after a successful login. After the user logs in and your application accepts the login by calling the 
/oauth2/auth/requests/login/accept
endpoint with the 
login_challenge
, Ory will redirect the user back to your application with a URL that looks something like this:
Copy code
<https://domain/callback?code=AUTHORIZATION_CODE&state=xx>
In this URL, 
AUTHORIZATION_CODE
is the authorization code that Ory generated. This is the code that your application should exchange for an access token. If you're not seeing a URL like this after a successful login, make sure that you're correctly accepting the login and that the 
redirect_uri
you're providing in the initial authorization request matches one of the redirect URIs that you registered with your OAuth 2.0 client. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/oauth2-oidc/authorization-code-flow#step-3-exchange-the-authorization-code-for-an-access-token).

my bad, there's also the login verifier, looks like this (this is the url that i get when i call 
acceptOAuth2LoginRequest
from the OAuth2Api) : "https://domain/oauth2/auth?client_id=xxxx&amp;login_verifier=xx&amp;redirect_uri=domain&amp;response_type=code&amp;scope=xx&amp;state=xx"
@chilly-king-10285 my bad, there's also the login verifier, looks like this (this is the url that i get when i call 
acceptOAuth2LoginRequest
from the OAuth2Api) : "https://domain/oauth2/auth?client_id=xxxx&amp;login_verifier=xx&amp;redirect_uri=domain&amp;response_type=code&amp;scope=xx&amp;state=xx"
c
A message from kapa.ai
The URL you provided is the one that Ory generates when your application successfully completes the login flow by calling the 
acceptOAuth2LoginRequest
method from the 
OAuth2Api
. The 
login_verifier
parameter in the URL is a value that Ory generates to indicate that the login was successful. However, this URL is not the one that contains the authorization code. After the user is redirected to this URL, Ory will initiate the consent flow. Once the user successfully completes the consent flow (which typically involves your application showing a screen where the user grants the requested permissions), Ory will redirect the user back to your application with the authorization code. The redirect URL with the authorization code will look something like this:
Copy code
<https://domain/callback?code=AUTHORIZATION_CODE&state=xx>
In this URL, 
AUTHORIZATION_CODE
is the authorization code that Ory generated. This is the code that your application should exchange for an access token. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/oauth2-oidc/authorization-code-flow#step-3-exchange-the-authorization-code-for-an-access-token).
m
@chilly-king-10285 we have the consent flow skipped in our oAuth client settings
c
A message from kapa.ai
If you have the consent flow skipped in your OAuth client settings, Ory will not initiate the consent flow after a successful login. Instead, it will immediately redirect the user back to your application with the authorization code. The redirect URL with the authorization code will look something like this:
Copy code
<https://domain/callback?code=AUTHORIZATION_CODE&state=xx>
In this URL, 
AUTHORIZATION_CODE
is the authorization code that Ory generated. This is the code that your application should exchange for an access token. To extract the authorization code from the URL in a JavaScript application, you can use the 
URLSearchParams
interface:
Copy code
javascript const urlParams = new URLSearchParams(window.location.search); const authorizationCode = urlParams.get('code');

window.location.search
is the query string part of the URL (including the leading 
?
character), and 
urlParams.get('code')
gets the value of the 
code
parameter. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/oauth2-oidc/authorization-code-flow#step-3-exchange-the-authorization-code-for-an-access-token).
m
@chilly-king-10285 so as I said, if the consent flow is skipped, this is the url that i get when i call 
acceptOAuth2LoginRequest
from the OAuth2Api) : "https://domain/oauth2/auth?client_id=xxxx&amp;login_verifier=xx&amp;redirect_uri=domain&amp;response_type=code&amp;scope=xx&amp;state=xx" I guess the login_verifier is the code I need?
c
A message from kapa.ai
No, the 
login_verifier
is not the same as the authorization code. The 
login_verifier
is a value that Ory generates to indicate that the login was successful. It's used internally by Ory and is not meant to be used by your application. After your application calls 
acceptOAuth2LoginRequest
, Ory will redirect the user back to your application with the authorization code in the URL. This is the code that your application should exchange for an access token. The redirect URL with the authorization code will look something like this:
Copy code
<https://domain/callback?code=AUTHORIZATION_CODE&state=xx>
In this URL, 
AUTHORIZATION_CODE
is the authorization code that Ory generated. This is the code that your application should exchange for an access token. To extract the authorization code from the URL in a JavaScript application, you can use the 
URLSearchParams
interface:
Copy code
javascript const urlParams = new URLSearchParams(window.location.search); const authorizationCode = urlParams.get('code');
In this code, 
window.location.search
is the query string part of the URL (including the leading 
?
character), and 
urlParams.get('code')
gets the value of the 
code
parameter. For more information, you can refer to the [Ory documentation](https://www.ory.sh/docs/oauth2-oidc/authorization-code-flow#step-3-exchange-the-authorization-code-for-an-access-token).

@sparse-father-97864 any idea why the 
acceptOAuth2LoginRequest
would not give me the code this kapa bot is talking about?
s
Yeah I've read through this thread but I'd address 2 things. 1) it looks like there's a little confusion around how the Authorization Code flow operates 2) I'll address the error message you mentioned in your first question to kapa. 1. Authorization Code flow is not dictated by Ory, it's laid out in these RFCs. They're very dry and hard to read (if you're ADHD like me) but there's a lot of good info. Also this site has some good high level info. https://oauth.net/2/grant-types/authorization-code/ But to boil down what I think might be confusing you here is that Authorization Code flow involves 3 steps. 1) a GET request to 
/oauth/authorize
for an authorization_code that prompts for username/password user login 1.5) (optional) a consent step that asks the user that put their credentials to approve use of their account information 2) a redirect to the redirect_url you provided with an auth code provided as 
code
3) a POST request to 
/oauth/token
to exchange the 
code
for an access token. In step 3 the request to exchange the code for an access_token requires that you provide the 
client_id
, 
client_secret
, 
code
(that you got from step 2), and 
redirect_url
(where you want the access_token to be sent in the end) 2. In my experience with OAuth2, I've seen the error you mentioned above of 
Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method)
usually comes from a failure on that 3rd step. Usually it comes down to using an invalid 
client_id
or 
client_secret
being passed with the code on that last exchange. That said, I haven't played much with the Ory SDK so I'm not sure what exactly 
acceptOAuth2LoginRequest
is doing under the hood. If you share more code around the exact example that's failing I could try to reproduce the error and help.
m
thank you @sparse-father-97864 for the long form response, 2. was already fixed, but still having problems with 1. The flow which I am using is - hit http://domain/oauth2/auth?response_type=code&amp;client_id=xx&amp;redirect_uri=xx - this gives me back the 
login_challange
parameter. I send the parameter to backend and use it to call 
getOAuth2LoginRequest
with this 
login_challenge
parameter, then call 
acceptOAuth2LoginRequest
with the 
userId
of logged in user. This returns the return url that looks like this "https://domain/oauth2/auth?client_id=xxxx&amp;login_verifier=xx&amp;redirect_uri=domain&amp;response_type=code&amp;scope=xx&amp;state=xx". Everything seems to be working as expected apart from the fact that during this process I am not able to see authorization code returned anywhere. I took these steps from https://www.ory.sh/docs/oauth2-oidc/custom-login-consent/flow#login-endpoint-code-example My code is almost the same as in this example but I will post here just to be sure:
Copy code
const userId = data.identity.id;
    
    const { data: loginRequest } = await oryOAuth.getOAuth2LoginRequest({
      loginChallenge: challenge,
    });

if (loginRequest.client.skip_consent) {
      const { data } = await oryOAuth
        .acceptOAuth2LoginRequest({
          loginChallenge: challenge,
          acceptOAuth2LoginRequest: {
            subject: userId,
          },
        })        
        
        return NextResponse.json({ data }, { status: 200 });
    }
It doesn't seem like i need the 
/oauth/authorize
in this flow? I am receiving everything correctly, the return url just doesnt contain the code
s
The call to 
/oauth/authorize
(or rather the Ory version of that endpoint which in this case is 
/oauth2/auth
) is happening, but the SDK is making that call for you in the background when you're calling 
oryOAuth.getOAuth2LoginRequest()
. The use of the loginChallenge here is actually a step beyond the Authorization Code stuff I mentioned above into something called PKCE (Proof Key for Code Exchange). Here's some good general docs on how that works: https://www.oauth.com/oauth2-servers/pkce/ - https://www.oauth.com/oauth2-servers/pkce/authorization-request/ (they use code_challenge instead of loginChallenge but I think it's the same concept here)
In your example though I will need to look closer at the node sdk for what it does with 
getOAuth2LoginRequest()
and 
acceptOAuth2LoginRequest()
. For a little more context though, how are you forming the 
challenge
you're passing in as your 
loginChallenge
bits here?
Okay, it looks like you might just be crossing wires between the Login Endpoint interaction and the Consent Endpoint interaction.
From your description it sounds like you run this flow and in the end you just get back a response just like this
Copy code
<https://domain/oauth2/auth?client_id=xxxx&login_verifier=xx&redirect_uri=domain&response_type=code&scope=xx&state=xx>
and there's no code so you're wondering why there's no 
code
, am I right?
l
@melodic-oil-50942, you need to redirect to the url provided in the 
acceptOAuth2LoginRequest
response e.g. 
<https://domain/oauth2/auth?client_id=xxxx&login_verifier=xx&redirect_uri=domain&response_type=code&scope=xx&state=xx>
. That endpoint is controlled by Ory and will redirect to the consent endpoint. Provided you have it configured to skip consent, it should redirect the browser a few more times and eventually end up at your OAuth callback endpoint with the 
code
and 
state
values in the search params.

Thank you both @sparse-father-97864 & @limited-photographer-61008, I have tried to go that url even previously, but after another redirect it just takes me to: http://domain/challenge?error=request_forbidden&amp;error_description=The+request+is+not+allowed.+No+CSRF+value+available+in+the+session+cookie.&amp;state=xx the 
/challenge
endpoint should be my oAuth2 callback (i think)
l
A screenshot of all the network requests might help debug
m
@limited-photographer-61008 here's the failling req
hard to screenshot more as the redirect is going from another page and cleans up the network page
i dm'ed you with a video of the full behavior since i didn't want to send it here publicly
could that be cross-site issue since im going from localhost:3001 to localhost:3000?
another thing i have just realized is that the 
return_url
i get from 
acceptOAuth2LoginRequest
points to dev deployment ory domain, not the localhost ory domain, when I change that and hit the correct domain, i get redirected to a link like this: 
http://localhost:3001/auth?consent_challenge=xx
but without any code I can use to retrieve the JWT so seems like the CSRF issue is resolved by changing to the correct domain, but the new url with 
consent_challenge
doesn't redirect me anywhere
@limited-photographer-61008 just pinging here, idk if those normal messages ping you or not

now resolved! thank you both for help it really saved me hours of scratching my head
