# Passing the module name for captcha recognition

> Passing the module name to recognize a specific captcha can be useful in cases of working with a specific service (e.g. Google, SolveMedia, Whatsapp, etc.).  This will increase the speed and quality of recognition and reduce the probability of errors.

When working with automatic CAPTCHA recognition, recognition accuracy and processing speed are important. Different services use their own CAPTCHA types, and a universal solution may not handle all of them equally effectively. For example, CAPTCHAs from **Google**, **SolveMedia**, **WhatsApp**, or **Yandex** may have specific characteristics that can cause the standard recognition module to work more slowly or produce errors.

To improve efficiency and reduce the likelihood of incorrect recognition, CapMonster Cloud allows you to specify the module that will process your CAPTCHA. The system will use a specialized recognition algorithm designed for the specific service instead of the universal CAPTCHA processing method.

## How to pass the module name in CapMonster Cloud using only the ApiKey field

If the integration provides only a field for the API key, append the required module name to the key using the following format:

```text
{apikey}__module-name
```

For example:

```text
00f87cb0f01330d33709ce3339ad0c8c__solvemedia
```

The API key and module name must be separated by **two underscores (****`__`****)**.
