The API key is a code that enables access to DeepL API. It looks similar to the code below:

The API key lets you integrate DeepL's translation technology with your own products, services, and plugins (excluding CAT tools). 

 

It is possible to create more than one API key for your subscription. To learn how to export key-level CSV reports, see this article. 

 

If you are not sure which subscription you need for the integration, contact your third-party plugin provider.

If you can't find an API key in your DeepL account, check that you are subscribed to the right ‌plan.

The DeepL API for Write is accessed through the same API keys that you use to access all other DeepL API endpoints.
