# OpenAI API Key for WPML for AI Translation

**WPML** is a popular multilingual WordPress plugin that helps you translate your website into different languages. You can translate your content **manually** or use **WPML’s automatic translation feature**.

No doubt, **Manual translation **gives you full control over the content, but translating every page, post, product, and website string takes a lot of time and effort. 

The work becomes even more difficult when your website has hundreds of pages and needs to support several languages.

On the other hand, **WPML’s automatic translation** feature makes the translation process faster, but it works using the translation credit system. 

Every time you translate your website content, **credits are deducted**, and as your website grows, you need to purchase more credits.

If you're looking for a more **cost-effective** way to automate translations, there's a better alternative.

[![wpml vs openai translation](https://coolplugins.net/wp-content/uploads/2026/07/wpml-vs-openai-translation.jpg)](https://coolplugins.net/wp-content/uploads/2026/07/wpml-vs-openai-translation.jpg)

Instead of relying on WPML translation credits, you can use your own **OpenAI** API key for WPML to power AI translations. With [**AutoMLP - AI Translation for WPML**](https://translatexyz.com/plugin/automlp-wpml-ai-translation/), you can connect OpenAI's models while paying directly for your API usage, while reducing translation costs. 

In this guide, we'll show you how to connect your own **OpenAI** API key with WPML and automatically translate your WordPress website without using WPML translation credits. 

## Why Use Your Own OpenAI API Key for WPML?

**WPML** already provides automatic translation, so you may wonder why you should connect a separate OpenAI API key for automatic translation. The main reasons are:

- **Avoid Depending Only on WPML Translation Credits: **WPML provides free translation credits with eligible plans. Once those credits are used, you need to purchase additional credits or enable pay-as-you-go billing. The total cost increases when you have a large website, several target languages, or content that changes regularly.

When you connect your own OpenAI API key through AutoMLP, you pay OpenAI directly for the API usage. You are no longer limited to using only WPML’s automatic translation credit system for these translations.

- **Pay for Your Actual API Usage: **OpenAI API usage is charged separately according to the amount of content processed by the selected AI model.

This gives you more control over how much content you translate. You can translate a few pages first, check the quality and usage, and then continue with the remaining content.

[***Note:** It is important to understand that OpenAI API access is not the same as a ChatGPT subscription. ChatGPT and the OpenAI API have separate billing systems. Even when you have a paid ChatGPT plan, you may still need to add billing details separately to your OpenAI API account.]

Using your own OpenAI API key does not mean that translation becomes completely free. The difference is how you pay and how much you pay for the translation.

- **Generate More Natural Translations: **OpenAI can understand the meaning of a complete sentence instead of translating every word separately. This can help produce translations that sound clearer and more natural in the target language.

However, AI translation should not be published without checking it. Important pages such as pricing pages, legal information, product details, and checkout messages should always be reviewed by someone who understands the target language.

- Next, choose **OpenAI** as the translation engine.

> [**Important:** OpenAI translation requires a valid **OpenAI API key**. The OpenAI key is not included with the plugin and is not provided as part of the plugin ZIP file. To use OpenAI for automatic translations, you must purchase an OpenAI API subscription separately and generate your own API key from your OpenAI account.]

- The translation process will begin automatically.

[![review translations](https://coolplugins.net/wp-content/uploads/2026/07/review-translations.png)](https://coolplugins.net/wp-content/uploads/2026/07/review-translations.png)

- After the process is complete, you can check the translated versions of the selected pages.

Pay special attention to words that should not be translated, such as company names, product names, technical terms, and registered trademarks.

## Conclusion

After discussing all the things above, it must have been clear that **OpenAI WPML integration** gives you another way to handle automatic translation.

With **AutoMLP – AI Translation for WPML**, you can connect your OpenAI account, select the content you want to translate, and create translated versions inside your existing WPML setup.

This method does not make translation completely free. However, it provides accurate and fast translation at a low cost (you are saving almost 95%)

Before ending this blog, here is my quick suggestion for you: Start with a small number of pages, review the results carefully, **monitor your OpenAI usage**, and **compare it with WPML automatic translation credits** by yourself. Once you are satisfied with the translation quality, you can continue translating the rest of your WordPress website.
