Extension Integration

This section describes how an extension author can get his extension setup at Crowdin.


Important to know

  • Your extension must be on GitHub, BitBucket or GitLab
  • Currently TYPO3 can only handle one branch/version for languages, more to that later.


Get in contact with the team in the TYPO3 slack channel cig-crowdin-localization with the following information:

  1. Extension name
  2. Information if your extension is already available on the previous translation server
  3. Your email address for an invitation to Crowdin, so you will get the correct role for your project.


You need to handle the integration yourself as you got the permissions on GitHub.

Go to the url of your project at Crowdin (e.g. https://crowdin.com/project/typo3-extension-ttaddress) and switch to Settings & then switch to the tab Integrations. Click on the button Setup integration.

This will open a new modal and will ask for the Configuration file name. We propose the file name .crowdin.yaml

Setting for translation pushes

Adopt the file name and press Continue.

Now you need to define where the language files are located.

Location of translation files

Typically the following setup will workout fine:

  • Source file path: /Resources/Private/Language/
  • Translated file path: /%original_path%/%two_letters_code%.%original_file_name%

Please check in the right area of the model if all xlf files have been identified.

Now press the green save button in upper left corner and then the save button in lower right corner.

Now press the last save button and you are done!

After a short time you should see something like that


Happy translating!
