    Try API endpoints

    To translate text files, you’ll need to use these two endpoints in this order:

    1. Upload a translation file
    2. Create a translation task
    Fill in the other parameters, like task description, due date, task type ‘translation’, source and target languages, and then click ‘try it’ to get an instant response. Click on the clipboard icon to copy the response or go to your Lokalise project to see updates triggered by your endpoints.

    Get translated text

    Once files have been uploaded, and your translation task has been assigned and completed, fetch translations using the ‘Download files’ endpoint.

    Note: if you want to translate with AI, you’ll need to set up automations inside Lokalise that trigger machine translations as soon as you create a task via the API.
