DeepL's mission is to overcome language barriers and bring cultures closer together. In order to achieve that mission, we use our expertise in artificial intelligence and neural networks to create technologies that make communication faster, better, and easier.
The DeepL API Connector allows you to use the DeepL API in your flows. Translate text or documents on the fly or manage your glossaries. Any functionality we offer with DeepL API can be used in Power Automate as well.
Prerequisites & Credentials
To use the connector, a DeepL API Free or Pro subscription is required. You can sign up here. After signing up, you can find your authentication key in the "Account" tab in your DeepL API account.
While creating your flow, you'll be asked to specify whether you have a Free or Pro plan. This has to be selected accordingly.
Get started with your connector
Start to add a new flow as usually and choose one of the available DeepL actions. Doing that for the first time will ask you to add some connection details as seen below:
Choose the price plan accordingly and add your API Key. The name can be anything you want. Confirm the step with "Create" and after that you can use the connection for all other actions available.
Known issues and limitations
We can not auto-detect your price plan. You have to choose between Free and Pro yourself when setting up a flow for the first time.
Some endpoints do not support JSON but only work with URLFormEncoded content, and while the connector has an internal workaround, this might not always work for everyone.
Common errors and remedies
HTTP 429 - A 429 error can be caused by multiple issues: either you tried to call the API too often, or there might be a temporary issue on our end. The general recommendation is to use an exponential back-off approach and retry the call. Exponential back-off is not implemented by the connector itself.
HTTP 400 - Something was wrong with your call, payload, or parameters used.
HTTP 456 - Quota exceeded. If you get a 456 error, your account limit for characters has been reached and you need to either wait until the next usage period or upgrade your account. If you're a Free API user, you can upgrade in the "Plan" tab of your account.
FAQ
- What is the difference between DeepL API Free and Pro plans?
DeepL API Free is a variant of our DeepL API Pro plan that lets you translate up to 500,000 characters per month for free.
For more advanced needs, the DeepL API Pro plan offers the following additional benefits:
Maximum data security (your texts are deleted immediately after the translation)
No volume restriction on the number of characters you can translate per month (a billing model based on a fixed price of €4.99 per month + usage-based costs of €0.00002 per translated character)
Prioritized execution of translation requests
Learn more in our help center.
- What if I reached my character limit on the Free plan?
If you reached your monthly character limit on Deepl API Free, you'll have to wait until the next usage period (i.e. month) to be able to use the API again. Alternatively, you can consider upgrading to a Pro API subscription in the "Plan" tab of your account.
- As a Pro subscriber, is there a way to limit my usage-based costs?
Yes, you can activate the cost control feature from the "Plan" tab of your Pro account.. Learn more about cost control in our help center.
- Which functionality is available using the connector?
Anything you can currently do with our API can be done using the connector as well. You can look here to see all supported functionality and additional documentation about parameters and details.
