How to obtain temporary authorization code in Slack API? - oauth-2.0

I am referring https://api.slack.com/docs/oauth#flow to obtain access token in PostMan.
Also, I have downloaded repo of slack api from https://github.com/lonelyclaud/slack-api-postman
Below command returns status 200, but no authorization code.
curl -X GET \
'https://slack.com/oauth/authorize?client_id=9XX331444993.996747590037&scope=team%3Aread+users%3Aread%20' \
-H 'Postman-Token: f2dc4c20-5b7d-4ed2-b71f-08ecad81fd8c' \
-H 'cache-control: no-cache'
Can someone explain how to obtain code, which in turn will be used to obtain token?

Got my answer, here is the link to obtain the auth token using Postman Create a Slack app and authenticate with Postman

how to make curl requests to app protected by AzureAD oauth2

I have an app which is protected by azureAD app registration. everytime user hits an URL, say, https://myapp.com/listall in browser they are presented with azure login screen. This is working as expected.
I was wondering how can I make curl requests to these endpoints from my terminal. When I try it now I get 302 NOT FOUND, as my request is getting redirected to login screen. when I try this form postman I see browser(HTML, CSS) code for azures login screen.
I am expecting something like.
make a curl request to obtain a token.
Use this token to subsequent curl requests.
I am making this curl request to get a token
-H "Content-Type: application/x-www-form-urlencoded" \
--data \
"
grant_type=client_credentials&
client_id=<client-id>&
client_secret=<client-secret>&
resource=https%3A%2F%2Fmanagement.core.windows.net%2F
"
I get a token back and then I make request something like this.
curl -X GET "https://myapp.com/listall" -H 'Content-Type: application/json' -H "Authorization: Bearer eyJ0eXAiOiJKV1....."
am I on the right path? how can I achieve this so that I can make curl requests to apps protected by azure AD app registration ?
I tried to reproduce the same in my environment and got the access token successfully.
Please note that the resource URL you are using is for classic deployed resources and https://management.core.windows.net/ corresponds to Azure Service Management API which is now changed to https://management.azure.com/
To get the access token, I made CURL request like below:
curl -X POST -H 'Content-Type: application/x-www-form-urlencoded' \
https://login.microsoftonline.com/your_tenant_id/oauth2/token\
-d 'client_id=your_app_client_id' \
-d 'grant_type=client_credentials' \
-d 'resource=https://management.azure.com/' \
-d 'client_secret=*******************'
To call the above CURL request in Postman, please follow below steps:
Run Postman -> Import -> Select Raw Text -> Copy the above CURL request and paste in raw text field -> Continue -> Import -> Send.
Response:
After getting the token, I made API call like below:
curl -X GET "Your_API_Call_http_link" -H 'Content-Type: application/json' -H "Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJS....."
Make sure to grant API permissions for your API before calling it in Postman. Ensure to select access tokens and id tokens check boxes for your Azure AD app.

getting Authorization Code from Oauth2Login

I'm logging to my app using oauth2 with keycloak. How can i get the authorization code that oauth2 should return?
I need it to get the token from an authorization server using following curl:
curl -X POST \
https://url/protocol/openid-connect/token \
-H 'cache-control: no-cache' \
-H 'content-type: application/x-www-form-urlencoded' \
-d 'grant_type=authorization_code&client_id=app_id&authorization_code=<authorization_code>'
here is sample request to take authorization code
GET http://<authorization-server>/oauth/authorize?response_type=code&client_id=app_id&redirect_uri=http:%3A%2F%2Fyourapplication.com%2F/login
these informations (client_id and redirect_uri) must be registered at authorization server, and authorization code url is generally /oauth/authorize but check your openid providers' url. (in your case, probably /openid-connect/authorize)
after hitting this request, the authorization server redirects you to login page. you enter your credentials, then it redirects you with code to your application which provided by redirect_uri. For example,
HTTP 302, http://yourapplication.com/login?code=<your-authorization-code>

Adding private key to Google audio to text API

I have submitted a request for google Audio to text. I received the name back, but I am unsure how to add private key info from file downloaded to:
curl -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
"https://speech.googleapis.com/v1/operations/your-operation-name"
and then am I able to run the command from web or Mac?
You can set up the environment variable to use the private key as mentioned here. Though the link talks about Vision API, the process is similar to use Cloud Speech-to-Text API. Also, here is additional documentation for authentication. This can be run from the web.

google api machine learning can I use an API KEY?

For learning purposes, I'm trying to use the Machine learning (ml) API.
https://cloud.google.com/ml-engine/reference/rest/v1/projects.models/list
I'm not able to identify if this request can be done with an API KEY instead of OAUTH.
I'm using npm package googleapis with this;
ml.projects.models.list({
key: GCLOUD_API,
parent: "projects/"+GCLOUD_PROJECT
}
But always receives this error:
Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential
I've tried replacing key with auth or token. Nothing work.
How can I know if is possible or not to use an api key?
I tried also with curl
'https://ml.googleapis.com/v1/projects/myproject-123456/models?token=my_super_sekret_key'
Today I had the same doubt.
Here are GCP Services that support API Keys:
https://cloud.google.com/docs/authentication/api-keys and ML API is not included.
You should obtain the access token using OAuth2, so URL POST request will be:
https://ml.googleapis.com/v1/projects/your_project/models?access_token=your_access_token
Works great for me. Same to do predictions.
1
You can get the auth token using gcloud:
access_token=$(gcloud auth application-default print-access-token)
and then embed it into the header:
curl --silent \
-H "Authorization: Bearer $access_token" \
-H "Content-Type: application/json" \
-X POST \
-d "$request" \
https://ml.googleapis.com/v1/projects/myproject-123456/models

LinkedIn OAuth2 revoke/invalidate token

In the documentation I have read:
"Now you can invalidate an OAuth token for your application. Just send an OAuth signed GET request to https://api.linkedin.com/uas/oauth/invalidateToken"
When I try it (LinkedIn REST API Console or C# WebRequest), It sends me Bad request (400).
It can be that is an old method when LinkedIn authentication process is OAuth1.
How can I invalidate/revoke access token in LinkedIn api with OAuth2 authorization?
Thanks in advance!
Since previous APIs will be deprecated(if not already) and V2 will be the one in usage, I have the way to revoke token on that API:
curl --request POST \
--url https://www.linkedin.com/oauth/v2/revoke \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data client_id=CLIENT_ID_HERE \
--data client_secret=CLIENT_SECRET_HERE \
--data token=YOUR_TOKEN_HERE
