Version Management
Maintain an agile localization process and avoid translation delays for added texts or new product features. Integrate your project branches with Crowdin and allow translators to access all new texts immediately.
Ветви
When several people are working on product development, branches help to manage different versions of the content. If you have a continuous project, you can add project branches to Crowdin and allow translators to translate the texts in parallel with development to avoid deployment delays.
The branch in Crowdin looks like a regular folder marked with a special icon and has specific behavior for duplicated strings.
Example of branch structure in the version control system (VCS) and Crowdin:
Branch Creation
Note! The first files you upload to the Crowdin project must contain all the original strings and should be placed in the corresponding branch. For all article examples, a branch with original texts is named Master.
There are a few ways to add branches to Crowdin:
- Integrate Crowdin projects with GitLab, GitHub, Bitbucket, or Azure Repos. It’s a recommended option, as branches selected for localization in your version control system (VCS) will be created in Crowdin automatically.
- Use CLI or API to add new branches.
- Create branches manually.
Branch Creation using API
To create a branch via API, use the Add Branch method.
Branch Management using CLI
If you use CLI, you can add and delete version branches with dedicated commands. Alternatively, you can create version branches during the file upload.

Prioritizing Branches
You can set a specific priority for each branch by clicking an arrow icon next to the needed branch. Then translators will see branches sorted according to their priority on the language page and in the Editor.
Branches might have the following priorities:
– low
– normal
– high
To set a priority for your branches, follow these steps:
- Open your project and go to Content > Files.
- Click an arrow icon next to the needed branch to set the preferred priority.
Дубликаты
Because branches are different versions of the same product feature, their localization content is usually duplicated. To help translators translate versions consistently and avoid additional translation costs, we have the Show within a version branch option that allows hiding duplicated strings only between versions. If your source files contain strings with apparent identifiers (keys), it’s better to use a strict version of this option. In other cases, feel free to use a regular one.
When this option is chosen, only the master strings first uploaded to the system should be translated. All duplicated strings will automatically gain translations from the master strings. 
Suggested Workflow
To make sure versions work smoothly for your Crowdin project, we recommend the following workflow:
- Upload your project files to the Crowdin project using one of the available methods.
- Open your project and go to the Settings tab.
- Scroll down to Source Strings > Duplicate Strings and choose the option recommended for versions.
The screenshot below visualizes how the workflow works in practice. All texts from Master, Branch 1 and Branch 2 are transferred to the translation server immediately after they appear, even though the branches are not merged to the Master branch yet. 
Translation Download
Translations from all version branches are placed in one ZIP archive when downloaded through the web interface. Use the CLI or API to download the translations for each branch individually.
Translation Download using API
To download translations of the specified version branch with API, you can use the following API methods:
- Build Project Translation - make sure to use the CrowdinTranslationCreateProjectBuildForm schema
- Check Project Build Status
- Download Project Translations
Translation Download using CLI
Скачать переводы из указанной ветки версии:
$ crowdin download -b branch_name
Слияние ветвей
The Master branch will contain new texts from the Feature branches as soon as they are merged. While synchronizing with Crowdin, texts in the Master branch are populated with translations from the appropriate branch.
After synchronizing the updated Master branch with Crowdin, you can remove the Feature branch from Crowdin. All translations stored in the Master branch will remain.
Branch Translation Verification
You can verify translations on production using only the Feature branch before changes are merged with your Master branch. Such test deployment allows you to quickly revert to the original Master branch version if needed.
