PublicToken via LinkToken

[yogirajshakya]

I successfully generated link token via CreateLinkTokenRequest.
Now, I am trying to get a public token via CreatePublicTokenRequest, so that i can get an access token via ExchangeTokenRequest.
But, I am getting error "ErrorMessage = "This endpoint has been discontinued as of version '2020-09-14' of the API." in CreatePublicTokenRequest.
And in the parameters of CreatePublicTokenRequest, it is taking expecting AccessToken instead of LinkToken

var response = await client.CreatePublicTokenAsync(new Acklann.Plaid.Management.CreatePublicTokenRequest
{
ClientId = clientId,
Secret = clientSecret,
AccessToken = linkToken
});

Could anyone please help on this?

@yogirajshakya - Please review the following code: https://github.com/viceroypenguin/Going.Plaid/blob/master/tests/Plaid.Demo/Controllers/HomeController.cs#L25 Notice that the link token is provided to the browser, which then handles doing authentication. The browser then issues back to the server with a public token, which is translated to an access token. The access token is what you will keep long-term. Also, recommend you switch to Going.Plaid nuget package, which has more current and complete version of the APIs.

Thanks for replying. My bad I got some things wrong.
Still I am confused, what does this mean "The browser then issues back to the server with a public token, which is translated to an access token."
How can a browser issues a public token and how it can be translated into access token?

What I got from Plaid Postman collection, first I need to get a public token via public_token/create, then get the access token via public_token/exchange, by using public token.

I am really confused what APIs I actually need. I need to use Plaid with Stripe to authenticate user and make payment.
Could you please suggest any article or link for that?
And I am not sure which version of Going.Plaid, I need for Asp.Net core 3.1 and c#8.0.
