What Is a Translation API for IRB Submissions?
A translation API (Application Programming Interface) for IRB submissions is a service that allows researchers and institutions to programmatically integrate secure, high-accuracy machine translation into their research workflows. Instead of manually translating sensitive documents like consent forms or study protocols, a developer can send files to the API and receive a precise translation. For IRB purposes, these APIs must offer features beyond standard translation, including robust data security (HIPAA compliance), terminology management for consistency, document format preservation, and auditable processes. Selecting the best translation API is crucial for ensuring participant comprehension, maintaining regulatory compliance, and protecting sensitive data.
