Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

In today’s modern world, where everything is connected, it makes no sense to build a website or an application that can be accessed in just one language.

To reach a global target audience, businesses must make their products and services accessible in multiple languages. But how can they do so? Isn’t it exhausting to create multiple pages for every language manually?

That’s where translation APIs come into action.

Translation API: An Overview

A translation API allows you to translate your application or website content programmatically. It connects your application to a translation platform or a service seamlessly by abstracting the process of dealing with the translation service manually.

To summarize, here are the benefits of making your application multilingual by using a translation API:

  • Global Target Audience: By making your application multilingual, you remove the language barrier. That is especially important for global businesses targeting a much wider audience.
  • Localization: The concept of localization is about catering to your target audience in their local language. With the help of it, businesses can make their products more personalized.
  • Analytics: You can analyze your application performance after making it multilingual and improve your services based on local preferences.

Depending on a particular provider, translation APIs may offer various services and customization options. For instance, you may use various APIs to perform language identification, get alternative translations, set translation quality levels, etc.

Want to know more about different translation APIs? Here is a list of some of the translation API platforms.

Google Cloud offers a translation API which uses a pre-trained Neural Machine Translation model to translate text. It updates this NMT model on a regular basis to incorporate better techniques and training data.

The API can translate your content to and from around 100 language pairs with unlimited character translations per day. Not only that, it can detect the current language automatically and translate it accordingly. Currently, it supports around 135 languages.

It provides two editions: Cloud Translation Basic & Cloud Translation Advanced. The advanced edition has the upper hand over the basic edition in terms of features like adding glossaries and custom ML models.

Azure Translator

Supported programming languages include C#, Go, Java, Javascript, and Python.


There is also a no-translate feature, which lets you prevent a piece of text to not be translated. You can just add a notranslate class to your HTML or set the translate attribute to “no” just like this – translate="no".

The translator service offers a free plan and a pay-as-you-go option for catering to your specific business needs.


DeepL is a machine translation technology that provides an API to integrate it with websites and applications. Use cases of DeepL include website content translation, internal company communications for multinational companies, and creating multilingual products.
