Sage Business Cloud Accounting uses OAuth 2.0 for authentication. Truto handles the full OAuth flow — token exchange, refresh, and secure storage — so your end users can connect their Sage accounts without your team managing credentials or token lifecycle. ### Which version of the Sage API does this integration target? The integration targets the Sage Business Cloud Accounting API v3.1, which is the current RESTful JSON API. This is specific to Sage Business Cloud Accounting (formerly Sage One) and is distinct from APIs for Sage Intacct, Sage 50, or Sage 200. ### Is this integration available as a pre-built Unified API or tool? Sage Business Cloud Accounting is currently available as a built-on-request integration. Truto will build and configure the integration for your specific use case, handling auth, pagination, and API-specific quirks so you don't have to. ### What regions and localizations does Sage Business Cloud Accounting support? Sage Business Cloud Accounting has a strong footprint in the UK, Ireland, Canada, and South Africa. It supports localized tax compliance features such as Making Tax Digital (MTD) in the UK, with region-specific tax rates and ledger structures available through the API. ### Can I both read and write data to Sage through this integration? Yes. The Sage API v3.1 supports both read and write operations. Common read patterns include pulling ledger accounts, tax rates, bank balances, and invoice payment statuses. Common write patterns include creating sales invoices, purchase invoices, contacts, and payment records. ### How does Truto handle pagination and rate limits for the Sage API? Truto manages cursor-based pagination and respects the Sage API's rate limits automatically. Your application receives clean, complete result sets without needing to implement retry logic or page-through logic on your side.
