Welcome to the Turnitin Core API (TCA) developer portal

For more than 20 years, Turnitin has delivered products to help educators, researchers, and publishers ensure the integrity of written work in the classroom and publishing contexts. These applications are available for integration into other platforms--and, in fact, that is how Turnitin’s services are most often used.

With the Turnitin Core API, you can deliver the value of introducing a plagiarism and integrity check seamlessly into your workflow. The Turnitin Core API (TCA) will allow your organization to integrate Turnitin’s similarity checking service into your platform. The TCA integration will allow users to submit a file, generate a Similarity Report, and display it to users within your platform.
