Can't enable beta languages with the library?

[lunolunoluno]

I might be missing something but it seems like it is not possible to enable beta languages with this library.
In the documentation an enable_beta_languages is mentioned however it doesn't seems like it can be enabled using the library.

Can this parameter be enabled somewhere else or should I use the requests library and pass that parameter in the request instead?

Python version: 3.14
deepl-python version: 1.25.0

You can use the extra_body_parameters to pass in e.g. enable_beta_languages as follows:

import deepl

auth_key = "f63c02c5-f056-..."  # Replace with your key
deepl_client = deepl.DeepLClient(auth_key)

deepl_client.translate_text("How are you?", target_lang="ACE", extra_body_parameters={"enable_beta_languages":True})

We have not added a specific enable_beta_languages parameter to the client libraries.

import deepl

deepl_client.translate_text("How are you?", target_lang="MT", extra_body_parameters={"enable_beta_languages":True})

(small corrections from the answer given)

Thanks it works!

Thanks, too much JS recently, and there are apparently a few typos in the readme for this... :(
