How to authorize correctly with Trello via OAuth? - oauth

I am trying to Authorize via OAuth with Trello and I can't seem to get it right, even in postman.
I have followed their API docs and have got myself a developer key and I have used a little link they have in this article to get a valid auth token.
I tried including the API key and Auth token in the header and (in a separate test) in the body, as per their documentation.
Everything I try results in "unauthorized permission requested".
What am I doing wrong?

Ok so I had obviously made a mistake when trying the Header route.
It works now if I provide a header key called Authorization and the API key and Auth Token in the following format OAuth oauth_consumer_key="{{apiKey}}", oauth_token="{{apiToken}}".

Issue with invalid_grant error with Google Oauth2

Cheers everybody,
we have been deeply reading google documentation on exchanging access_token from google in order our (delphi)desktop application to SSO with google from server side. Here is the payload we send first look like:
https://accounts.google.com/o/oauth2/v2/auth?client_id=1000217514248-t1lojs6f8ed7l9ocrpbm98leahtum8n1.apps.googleusercontent.com&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&response_type=code&state=E1DF2FBA-0A66-4D69-B594-5EB8F7828AF7&scope=openid+profile&include_granted_scopes=true&code_challenge=C832DA50-E55A-499D-89B8-493BB4123C94&login_hint=test#Speelkriebel.be
Normally after this it redirects me to login in to our test user and after this according to the documentation we send a POST request to the end point token in order to get the access_token and refresh_token...: 'https://oauth2.googleapis.com/token
with the following parameters, the 'code' is generated we also send it as follow:
client_id=1000217514248-t1lojs6f8ed7l9ocrpbm98leahtum8n1.apps.googleusercontent.com
grant_type=authorization_code
client_secret=******
code= 4/1AY0e-g4GlavO38PI5Oo3vq04Pc4lMWN77et-02UiVWOsT-IyRQnU1lq19qo
redirect_uri = urn:ietf:wg:oauth:2.0:oob
The response is always
{
"error_description": "Missing code verifier.",
"error": "invalid_grant"
}
We have tried to send the client secret id also, Does it have to do with our code_challenge ? are the end points url and initial url okay? What are we missing? We are using CEF4Delphi as "browser like experience in order for the user to type in their google credentials. We have been reading this: https://developers.google.com/identity/protocols/oauth2/web-server#offline
We were also trying the playground :https://developers.google.com/oauthplayground/
we were sending the initial url in a chrome which generated a "code" and in the playground we inserted the code, and still got the same error of missing code verifier.
Thanks Guys
You seam to have URL encoded a lot of the values try not doing that. Also try using the basic call, before you start adding everything else. It should help you figure out which one of those extra parameters you are sending that's causing your issues.
https://accounts.google.com/o/oauth2/auth?client_id={clientid}&redirect_uri=urn:ietf:wg:oauth:2.0:oob&scope=profile&response_type=code
Also make sure that the client id is from an installed / other type client
This may also help Google 3 Legged OAuth2 Flow
For installed apps, the code challenge and verifier are parameters for enhancing the security of the OAuth flow through PKCE [1].
There is additional documentation about generating a code challenge and verifier here [2].

How to authenticate Freshdesk API in Zapier webhook?

I'm calling the Freshdesk API to update a ticket by adding tags. I'm having trouble authenticating the call. I have encoded username and password to base64(using an external tool).
I've tried the following:
Basic Auth: In Zapier's BasiAuth field, I tried username|password
In the header field, I added a key Authentication with value BasicUsername:password
In both cases I get the error You have to be logged in to perform this action.
Zapier's basic auth field should work if everything is set up correctly (and there's no | in your password). In that field, you should be using your actual password, not the base64 encoded pair: david:mypass.
If you want to do it manually, that's fine too. the Authentication header should be something like Basic asdfasdf==. Note the space between the word "basic" and the "base64" encoded username:password.
For everyone looking for the solution here...
I did a header and then did this with my API token
headers
Authorization
Token token=yourapicode
FreshDesk API - Authentication
I found this when trying to get Postman to work with their API, turns out you need to set Authorization type to Basic Auth, have your API token from FreshDesk as your username and just 'X' (without the apostrophes) as your password. Hope it helps someone else.

Oauth2.0 Google API token issue - Error: redirect_uri_mismatch

I have trouble creating a Google API OAuth2.0 token though following all the steps here: [OAuth2 Authentication](
https://developers.google.com/adwords/api/docs/guides/authentication?authuser=1)
When trying to create the token through the OAuth2.0 playground:
OAUTH 2.0 playground
I end up with this error:
Discussion on similar threads tried to give some guidance but without any luck in my case.
Add google.com in the authorized domain list of your app's OAuth consent screen.
Click on the application for which you want to configure for the next step:
Make sure to also add 'https://developers.google.com' in the Authorized JavaScript origins and 'https://developers.google.com/oauthplayground' in the Authorized redirect URIs[click 'save' below once added]:
You are applying your own client id and client secret to Oauth2 playground you are also using browser credentials.
For browser credentials to work it must be able to return the token to an endpoint that can handle it and that endpoint (Redirect uri) must be registered in the Google Developer console for that project.
if you check your first picture under the check box you clicked
You will need to list the URL https://developers.google.com/oauthplayground as a valid redirect URI in your Google APIs Console's project. Then enter the client ID and secret assigned to a web application on your project below:
Try adding that URL as it says.

How to request access token from Battle.net OAuth with authorization code?

I have a hobby project in mind to use battle.net login. I'm wondering how I can obtain the access token from the API after receiving the authorization code.
This is Oauth flow question rather than a battle.net question.
Currently I can successfully authorize the user for my app which is registered in dev.battle.net and then I try to use the authorization code returned from the battle.net login to obtain the access token by sending a request to https://<region>.battle.net/oauth/token.
However I keep receiving this error:
{
"error": "unauthorized",
"error_description": "An Authentication object was not found in the SecurityContext"
}
I use postman extension to send post requests to that uri. I authenticate my request with my client id and secret. I pass redirect_uri (https://localhost), granty_type (authorization_code), code(the code returned from the previous authorization step). However I keep getting the error above.
I couldn't find much about battle.net online. There are other oauth related help articles but couldn't really find my way.
Wondering if you can help me with this easy stuff. I'm just wondering what I'm skipping here.
Here is the documentation:
https://dev.battle.net/docs/read/oauth
https://localhost is added in my mashery dev account's app settings.
Me again, I resolved this problem after trying almost every combination in the universe:)
Steps to apply:
Don't use the same authorization token for different access token trials, they are not valid
Always use https on every domain you test including localhost, you
redirect_uri must be https as well.
You must use the "basic authentication" in the header of your POST request while requesting the token from the authorization code you obtained from the previous step.
This is one of the most important ones: For requesting token, Pass redirect_uri, client key and secret as POST form parameters to the authenticated request. This is interesting because it's already an authenticated request; why would i need to pass my secret again? Anyways, that's how it works.
Here are the full text:

Google's OpenID Connect says: OAuth 2 parameters can only have a single value: client_id

As part of the OpenID Connect (OAuth2 for Login), my application is supposed to request an access token, given a one-time authorization code, via the endpoint https://www.googleapis.com/oauth2/v3/token. According to documentation, this request needs 5 parameters passed to it, client_id among them. That is exactly what my application does, using the Perl module Net::OAuth2.
Everything has been working fine for several months, but today I was notified that it stopped working. No updates were made to the application code nor the libraries used by it.
The message my application now receives from the server when calling the token endpoint is this, in a 400 error response:
OAuth 2 parameters can only have a single value: client_id
A Google search suggests nobody has ever seen this message before, or lived to tell the tale. There doesn't seem to be a general issue with Google's OpenID Connect (other services based on it are working flawlessly), and the imminent shutdown of the old login protocol doesn't seem relevant.
More testing: removing all parameters except client_id causes this error message:
Required parameter is missing: grant_type
Supplying only client_id and grant_type produces the original error message again.
Does anyone have an idea what's going on here?
Google changed this behavior few days ago, so any OAuth2 library using Basic Auth headers AND body request parameters will start to see messages like
OAuth 2 parameters can only have a single value: client_id
or
OAuth 2 parameters can only have a single value: client_secret
So, you must now do NOT use both (the Auth headers and body request parameters) at the same time to send credentials to Google.
And according RFC 6749, the preferable way to send credentials is through Auth headers (thanks #JanKrüger for alert me about this).
Got the same error. It seems the problem is that NET::OAuth2 sets the authorization header when exchanging authorization code for access token. If you remove this header everything works fine.
Check the get_access_token method in Net::OAuth2::Profile::WebServer module. The authorization header includes client_id:client_secret base64-encoded string. Apparently Google now treats this duplication as an error.
The right way of fixing this is to set the secrets_in_params parameter when creating Net::OAuth2::Profile::WebServer object. Look in the Net::OAuth2::Profile documentation for more details.
