OAuth2 Library troubleshooting

Hi Sean, 
Thanks for the response - here and in the forum post.

The process is failing at step one before any attempt to return the token, so I think it’s a LiveCode OAuth library/documentation issue - as the parameters that open a blank browser dialogue in LC work fine in Postman’s token request form to get a login page returned.

Time to revisit the web viewer and attempt to roll my own.
Thanks
Keith

This url is used to send the token to in a browser request. If the page fails or does not exist then that token is never received. The guide on Salesforce site (the one you linked to) says:
