If you are the owner of a localization project, its administrator or the manager of a POEditor organization, you can easily add any of the supported languages to your projects.
How to add languages to a project
In POEditor, you can add languages to a single project in several ways.
Adding languages in the UI
To add languages from the existing language list, you can use the Add languages option in the Project page.
You also have the possibility to create custom languages of your choice. The option is further described here.
Copying the languages from another project
When you create a new project, you can copy the setup from an existing project, thus copying all its languages and adding them to the new one.
Adding a language via API
To add a language with the API, use the languages/add method.
If you want to add multiple languages with the API, you can create a script that would send a request for each language you want to add to the project.
How to add languages to multiple projects
To add languages to multiple projects in bulk, go to a project, click on Add languages, select your desired languages and then click on Add to more projects.
You can choose to add the languages just to some of your projects, or check the option All projects to have them added to all the projects hosted on your account or organization.
