Hi Kelly,

Thank you for your response and yes you are right about the IP; I didn't
realize first that the connection to the auth server is going thru oBrowser
(things make sense now).

Re- the error I'm getting 'invalid redirect URL', I started to think that my
problem is because I'm trying to access the auth server from Canada (outside
UK).
As I have created a new account, new client id, secret key and I have
registered the redirect URL there and still getting the same error.

This is what is written about the "redirect URIs" on their documentation:

"Your application needs your user's permission to interact with HMRC on
their behalf when accessing user-restricted endpoints. Users must sign in to
their Government Gateway account to grant this authority.
Afterwards, redirect URIs tell us where to return your users in your
application."

I'm not sure what do they mean by " Users must sign in to their Government
Gateway account to grant this authority"..
So no luck yet in getting the Auth token from the HMRC server.

Thank you,
Mayada

Hi Mayada,

I'm glad to know that localhost did work with you, which will make testing
easier for me, although I don't understand how the auth server will know
how
to reach it.

The auth server knows your IP because you request the auth code from it, so
that's the IP it responds to.


Else     ;; normal path for this DropBoxAccess demo...
;  Open the authorization URI in an oBrowser object by default.
Open window instance wAuth2Browser/CEN (uri)
;  uri = e.g. https://www.dropbox.com/1/oauth2/authorize?
;       ;; Accept=application/json
;       ;; &response_type=code
;       ;; &client_id=xyz4gddhgv8v7iy
;       ;; &state=7c633e9422a54a95d72052040f5ea642
;       ;;
&redirect_uri=http://localhost:9816/api/DropBoxAccess/oauth2/code
End If
;
;  Control returns via the redirectURL to the $onCodeReceived method, which
will use the code to request a token.     ;; (and remove the cAuthQueue
entry)


So you open the browser window and request the authorization code, the auth
server interacts with the user in that browser window and gets their
approval, then it calls back through the redirect URL (i.e. your remote
task's /code.$get URI method) to give you the code you need to request the
access token.  I'm just guessing that it would interpret 'localhost' as
'sender's IP'.  When it works you stop wondering...
