What Sage Intacct API is

Sage Intacct API is a web and API service for connecting organizations’ financial workflows through Sage Intacct Web Services. Sage says it offers more than 300 methods and uses structured XML-RPC: requests use XML, while responses may be XML, JSON, or CSV. SDKs support multiple programming languages, and Web Services is described as language agnostic. Integrations can begin inside or outside the Sage Intacct environment. The Marketplace lists solutions from more than 350 integration partners, including ADP, Expensify, Avalara, and Bitwave. Invoice synchronization and journal entries work in both directions, and a sandbox environment is available. Calls require developer sender and company user credentials; companies control permissions and whitelist source domains. Requests are logged and monitored. Usage is metered by transactions, with entitlements and concurrency limits tied to performance tier. Sage lists SOC 1, SOC 2, PCI, HIPAA, GDPR, and ISO 27001 certifications.
