# Custom Validation Managers

If you would like to adapt your own validation engines to work with ANY ColdBox application you can do this by implementing the following interfaces:

* Validation Manager : Implement the `cbvalidation.models.IValidationManager`. Then use the class path in your configuration file so it uses your validation manager instead of ours.
* Validation Results : Implement the `cbvalidation.models.result.IValidationResult`, which makes it possible for any ColdBox application to use your validation results.
* Validation Error : Implement the `cbvalidation.models.result.IValidationError`, which makes it possible for any ColdBox application to use your validation error representations.

Then map it in your configuration file:

{% code title="config/Coldbox.cfc" %}

```javascript
validation = {
    // The third-party validation manager to use, by default it uses CBValidation.
    manager = "my.class.path"
}
```

{% endcode %}
