Sage Intacct REST

Testing runs against an application registered at developer.sage.com/console with the Non-production client scope, pointed at a sandbox, trial or developer company. The scope cannot be changed after the application is created, so each environment needs its own registration, and its client credentials are separate from the production ones. A full sandbox company (a copy of production) is requested through a Sage support case and refreshed at most 4 times a year; it is not offered to companies managed through a Sage Intacct multi-entity console or purchased through a reseller. Several modules are unavailable inside a sandbox, including Fixed Assets, Collections, Prepaid Expense Amortization, Advanced Audit Trail and the interactive reporting tools, and a sandbox is valid only to the end of the production billing cycle.

Live companies require an application registered at developer.sage.com/console with the Production client scope, issued once your Web Services developer license is in place. ⚠️ Development credentials CANNOT be used with production accounts.
