Whether you are just getting started with DeepL API, or you already have an integration running in a production environment, sometimes it’s a great idea to have a safe test environment to try things out first. For convenience, we’ve created a Postman collection that mirrors the DeepL API functionality and lets you test your API in a structured environment. For more information about Postman, check out their overview. To get started, sign up for a developer account at deepl.com and get your authentication key from your account page. Click the button below to fork the DeepL API collection into your own Postman workspace: Run in Postman In your forked collection, select the relevant baseUrl variable depending on you subscription (https://api.deepl.com/v2 for Pro, https://api-free.deepl.com/v2 for Free). In the Authorization section of your forked collection, you will see the value DeepL-Auth-Key [yourAuthKey]. Change [yourAuthKey] for your own key and you’re ready to go!
