Postman updated - old oAuth callback URL has been deprecated

HI SirDale,

Thank you for reaching out. Yes that is correct, The Postman redirect URI of https://www.getpoastman.com/oauth2/callback has recently been deprecated. What you will need to do is update the redirect URI to the new value ofhttps://oauth.pstmn.io/v1/callback. This will need to be updated In My.Myob and your app when completing OAuth. 

Let us know if you have any questions, 

Thanks, 

Hi,

I made the change to postman (redirect_uri set to https://oauth.pstmn.io/v1/callback) but all that happens is that postman then gets a web page from MYOB with...

"Sign in to MYOB" (username, password fields shown), as well as 

"Uh-oh! The numbers don't add up." saying javascript isn't enabled, as well complaining about no cookies.

But this is to be expected given postman is not a browser.

If I change the redirect_uri to be "https://oauth.pstmn.io/v1/browser-callback" then I get the same response.

If I grab the initial web request from postman's consolse...

https://secure.myob.com/oauth2/account/authorize?client_id=<my client id>&redirect_uri=https://oauth.pstmn.io/v1/browser-callback&response_type=code&scope=CompanyFile

and put that into a browser (as demonstrated in the video) I don't get the MYOB authorisation page, but instead just get...

Authentication complete

You can close the tab and go back to the Postman app.

I had this running previously, but am completely stuck at the moment. I'm unable to make any progress until I can get authenticated. 

Please help!
