API (Application Programming Interface)
Description
In localization and translation workflows, APIs play a vital role in connecting Translation Management Systems (TMS), Machine Translation (MT) and Content Management Systems (CMS). They automate the flow of content between platforms – for example, transferring text from a website or software product directly into a translation environment, then returning localized versions automatically.
By minimizing manual steps, APIs improve scalability, reduce turnaround time and ensure linguistic consistency across markets. They also support continuous localization by enabling automated updates and synchronization of translation assets such as translation memories and termbases. Modern APIs utilize REST or SOAP standards to ensure secure, reliable data transmission, allowing enterprises to build custom connectors or leverage pre-built integrations.
For global organizations, API-led connectivity is the backbone of the content supply chain. It allows marketing, development and product teams to work in their native tools while localization happens seamlessly in the background. This removes the friction of file handling and version control, enabling a truly agile, "always-on" localization process that keeps pace with rapid content creation.
Example use cases
- CMS integration: Automatically pushing web content to a TMS for translation and retrieving it upon completion.
- Continuous localization: Connecting code repositories (like GitHub) to translation tools to localize UI strings during software builds.
- Machine translation: Sending text to a neural MT engine via API to get instant, secure translations within support apps or chat tools.
- Terminology management: Synchronizing approved termbases across authoring and translation platforms to ensure brand consistency.
