# Interactive Validations
The Interactive Validation performs checks on annotations before the data moves to the next stage in the [label validation](/3d-multi-sensor-fusion/labeling/3d-multi-sensor-fusion-labeling-editor/key-features/label-validation.md). It uses pre-defined validations set during the setup and highlights potential issues. The tool allows users to view, validate, and fix problems interactively without leaving the annotation workspace.
{% hint style="success" %} 
Validation enhances the workflow by ensuring consistent and high-quality results across various business requirements.
{% endhint %}
***
## Use cases
* Quality Assurance: Automatically catch incomplete or incorrect annotations
* Progression Control: Block data from progressing to the next stage (e.g., internal review, customer auditing) if it fails basic validation
* Consistency Check: Ensures consistency in object properties across frames and sequences
* Customer Business Rule: Enforce project-specific rules without manual checks
* Real Time Feedback: Show validation errors as annotators work, enabling faster correction
***
## Benefits
* Prevents invalid or incomplete annotations from progressing
* Saves time by linking validation errors directly to their locations
* Customizable per workflow to match specific project needs
* Non-disruptive: user can keep the report open while annotating

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.imerit.net/3d-multi-sensor-fusion/labeling/3d-multi-sensor-fusion-labeling-editor/key-features/interactive-validations.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
