Using translation software is the new normal for translation, but how can they assist in translating your app or web content? It usually happens through APIs. For understanding translation APIs is we must understand what an API is.

API stands for Application Programming Interface. Basically, by using an API, two applications can communicate with one another.

A translation API works as a software interface that developers can use to add machine translation capabilities to their products or programmatically translate texts and content that their product displays in localized versions.

Localazy provides a Translation API as one way of integrating of software translation projects.

Localazy API can be used to fetch up-to-date translated content, modify it or upload new content for translation. You can also manipulate the source keys in the project, manage screenshots, duplicities, webhooks and glossary terms.

Localazy Translation API endpoints allow you to:

  • List your projects
  • Import content to a project
  • Retrieve a list of available file types
  • Retrieve a list of files in the project
  • Retrieve a list of keys and translations from file
  • Update or delete source keys
  • List glossary terms
  • Create, update or delete a glossary term
  • List and update your webhooks configuration
  • List screenshots and screenshot tags
  • Create a new screenshot
  • Update an existing screenshot or delete it
  • List, create or remove duplicity links

Some use-cases where API is applicable:

  • Keeping translations up-to-date in your application
  • Sending content from your CMS database for translation
  • Managing translation context assets programmatically

With Localazy API, you have great flexibility of implementation.

For example, when you want to provide up-to-date translations without having to release a new version of your application, you can fetch everything through API and only fall back to static files in case of an error or as a fallback until the files are properly fetched, or you can skip using the static files whatsoever and use API only.

Basically all you have to do is:

  1. Sign up and create a Localazy project
  2. Get your API access token
  3. Create an API service on your side
  4. Upload content in source language via API for translation
  5. Fetch translated content in a language of your choice

Well designed tool with many features

We are operating multiple complex websites with many localisations. Managing and keeping all dictionaries up-to-date was pure hell before we switched to Localazy. We are now easily able to review, manage and keep all dictionaries up-to-date whenever we add or modify any functionality.

Very powerful translation system with affordable cost

We looked for a solution that can cover several use cases across our project and Localazy is a clear winner. Thanks to CLI tools, git and branching, and features we could integrate Localazy with GitHub Actions for automated documentation translation delivery.

Developer- and translator-friendly service. Great user experience!

Localazy has been a game-changer for our localisation efforts. I have tried various localisation tools in the past, but Localazy stands out as the best one. It not only takes away all the headaches related to creating and maintaining up-to-date localisation resources and allows you to easily create a community that helps with the translation. The service offers a rich set of automation options, starting with technical ones such as a CLI that can be used in a CI pipeline or OTA/CDN updates/delivery and ending with various machine pre-translations or human-assisted continuous translation. And all that is on top of a responsive and attentive team behind the project.
