[Precise name of Accounting product as it relates to API enpoint availability? What is Start/Standard/Plus?]

I cannot match the Accounting product names as they appear in the API Documentation to the Business Cloud Accounting webpage where I choose the subscription.

When I look here: https://www.sage.com/en-ca/sage-business-cloud/accounting/ I see "Accounting Start" and "Accounting"  but I when I look here: https://developer.sage.com/api/accounting/api/invoicing-sales/#tag/Sales-Invoices I see Enpoint Availability list "Accounting Plus", "Accounting Standard", "Accounting Start".

The only one that maps straight across is "Start". What is Plus and Standard and why do I only have 2 subscription options?

If I buy the $30/month "Accounting", will I have the "Sales Invoices" API endpoint?

Thanks!

[Can't create new app, Top-Level Domain (TLD) not recognized]

Thanks for the quick action. Sorry for my late response, I didn't realize your forum defaults to not subscribing me to my own topics.

Yes, the fix worked for us and we can now start developing.

[Can't create new app, Top-Level Domain (TLD) not recognized]

When I try to create a new app, the callback URL does not accept our TLD (.systems). If I add something like ".com" to the domain it works fine. Is Sage using some very outdated URL validator? This is a show-stopping bug for our business. 

Thanks for looking into this.
