Hi Mark, Thank you for your response. Yes, the solution I am working on aims to provide continuous data synchronization between Sage Business Cloud Accounting and solutions from other companies. In my case, the OAuth flow is possible and completely secure, although it requires additional work and imposes certain limitations. Thank you for the information. Best regards, Bartłomiej

Hi, I am interested in using the Accounting API, and I have reviewed the documentation on authentication available at https://developer.sage.com/accounting/guides/authenticating/authentication/. I was wondering if there are any alternative methods of authentication available for the Accounting API and if the OAuth 2.0 method described in the documentation is the only option. Thank you in advance for your help and I look forward to response.
