If you have a license from a DeepL Pro Advanced, Ultimate, Team or Business
subscription purchased
before March 31, 2026, or from a DeepL for Enterprise subscription,
your license includes a valid
authentication key for CAT tool access. You can copy
the key from
your account.

If your subscription does not include an authentication
key for
CAT tool access, you will now need to purchase
a
DeepL
API Growth subscription.
- Note that you cannot add a Growth subscription if your account contains an active subscription already. In that case, create a new account using a different email address to subscribe to Growth.
- If you have a valid authentication key for CAT tool access but are receiving errors when trying to access DeepL from a CAT tool, please ensure that you have installed the latest CAT tool plugin version, see this article.
An authentication key is a code that enables you to use DeepL directly in your CAT tool.
The authentication key looks similar to: df4385c2-33de-e423-4134-ca1f7b3ea8b7.
Find your authentication key in your DeepL account in the Account tab, under Authentication Key.
The authentication key can be used in DeepL plugins offered by CAT tool providers to directly integrate DeepL Translator in your CAT tool.
Plugins are developed and maintained by the respective CAT tool provider. Should you encounter difficulties when using DeepL with your CAT tool, make sure that your plugin is up to date.
