The above is taking me to keycloak signup page and after successful signup redirecting back to my app. But here I want to get the user id of the registered user or any info about the user just registered but after redirection, I'm only getting session_state and code params. How to get id_token or anything from that I can get registered user details

according to your question, I can assume that you are using authorization code grant type. You need to exchange the received authorization code for a token.
Specification: https://openid.net/specs/openid-connect-core-1_0.html#CodeFlowAuth
Keycloak token endpoint : http://localhost:8080/auth/realms/{REALM_NAME}/protocol/openid-connect/token
All the available OIDC endpoints: http://localhost:8080/auth/realms/{REALM_NAME}/.well-known/openid-configuration

I'm researching to use OIDC for SSO (Single Sign On).
I know OIDC flow always return id_token and access_token but I don't know why we need id_token?
As I know id_token used only by client application to get authenticated user information. Client application will decode and verify JWT then extract user information from it.
But because I have access_token, I can use it to get user information from endpoint /userinfo. So I dont't need id_token?
Please help me understand the right way to use id_token.
You are correct that you can get the user details using the access token from the /userinfo endpoint.
The ID-token represents details about the user and more important how the user authenticated (password, 2FA...). The lifetime of the Id-token is often very short (like a few minutes).
Just like how the specification describes it:
The ID Token is a security token that contains Claims about the Authentication of an End-User by an Authorization Server when using a Client, and potentially other requested Claims.
I'm using Postman a lot for API development. Most of time I use OAuth 2.0 for authentication. As this post says, the Authorization Code flow steps are as below:
The application opens a browser to send the user to the OAuth server
The user sees the authorization prompt and approves the app’s request
The user is redirected back to the application with an authorization code in the query string
The application exchanges the authorization code for an access token
In step 3, I think the user is redirected back to the application by using the redirect url. But what we always provided in the request is the configured url for real application that should get the auth code instead of Postman. I'm quite confused how can Postman get the auth token as the redirect url has no info about it.
The identity provider will create the authorisation code and return it to the redirect URI as a query string parameter, in a parameter named code the url will be yourdomain.com/app?code=authorisation-code
In postman it is possible to retrieve an access token for a Authorisation Code flow client.
Click the authorisation tab for a request, in the type select oAuth 2
Then click the orange Get Access Token button, it will prompt a new window where you can input your client & idp information.
When you click the request token button it will prompt you to enter your credentials at this point it will retrieve the authorisation code and automatically exchange it for an access token using the client id, secret and scopes that you configured on this screen, if everything is successful then you will receive your access token.
I am currently tracking a question on how to automate this process to be executed as part of the execution runner: Postman - Access Token Retrieval using Authorisation Code grant type
I am reviewing OKTA. I have two authorization servers configured, the default one and a custom one. I have a client (web app) that is configured and correctly logging in. I am getting back the expected id_token and access_token. The problem I am running into, is how do I call an api, that is expecting an access token from the second authorization server? How do I request an access token on behalf of the logged in user (default auth server) from the second auth server, without prompting the user to login again? This is all done in .net core mvc application.
In each of your applications you can check for an active Okta session. If found initiate the OIDC AuthN flow.
This is the endpoint on the client you can use to check for an Active Session
https://developer.okta.com/docs/api/resources/sessions#get-current-session
You can use the following authorize URL to get the access token or id token
{{url}}/oauth2/{auth server ID}/v1/authorize?client_id={client id}&response_type=token&response_mode=fragment&scope=openid&nonce=nonce&state=state&redirect_uri={redirect url}
Get the auth server ID from the URL when you see visit the server in the UI.
The above call needs an active session so if you signed the user the first time with 'default' auth server recently. You don't need to sign the user again to get to the token for the second auth server.
I am implementing openid connect for google and microsoft. Openid provides the id_token which also content the user info. I am still confused. How to use id_token. In oauth2 we are storing the access_token in our db. so we use access_token to get user profile. If I am getting the profile mean user is authenticate and user will login into app. So in id_token case, should I validate the token. If token is validate then user will login. I am really confused. Please help me out. Please provide the flow of authentication.

TL;DR id_token removes the need for that extra round trip you need to make to get userinfo. Instead OIDC presents you with both an id_token which contains all the info you need about your current user and an access_token.
If token is not required for authentication. It is only useful in public clients to get some user attributes aka claims.
I need to generate or make url-link with inline token, that i can send to user email for only once login.
I found how get access_token for user for redirect to my endpoint (How do I obtain an OAuth token from WSO2 using the Consumer Key/Secret?), but I don't understand what to do next. I found how validate token, refresh it, but nothing about logon by token.
I need something like https://my_wso2is/auth_token?token=37133621-f099-33c4-b686-c017ed229fc0
You can use OIDC in order to get the user authenticated and then allow access to your application. You can find more information from [1] about how WSO2 IS works with OIDC using one of the sample applications named playground.
