Hi Mark, Thanks for your reply, I was unaware that I needed to also include the Postman callback URL in the App as well - I have done this, but it also hasn't worked. I have also been attempting the OAuth via the script I have been writing, and it ends up with the same authorisation error! Thanks

Hi All, I am currently developing an integration for Sage, but am having issues with the OAuth authentication. I have signed up for a trial Sage Cloud account, as well as a developer account and created an applicable app along with its relevant credentials. I have tried both through Postman using your documentation, and through my script I have written, but after logging in on the initial OAuth setup, it shows the following: Any help would be much appreciated! Thanks!
