Smartling is an enterprise translation management platform combining a cloud-based TMS, LinguisticAI, and neural machine translation. The Smartling REST API at api.smartling.com exposes authentication, accounts, projects, source files, strings, translations, jobs, glossary, issues, quality checks, MT, and reports. Authentication uses an OAuth-style userIdentifier + secret pair that returns a short-lived bearer access token (~5-10 minute TTL) with a refresh token.
