# Validate VAT endpoint

> The `validate` endpoint takes a VAT number in the request, checks if that number is valid, and if it is valid, returns addition details about the company associated with that VAT number.

## Getting started

### Base URL

```
https://vat.abstractapi.com/v1/validate
```

### Validation endpoint

The `validate` endpoint simply requires your unique API key and the VAT number you'd like to check:

```
https://vat.abstractapi.com/v1/validate
? api_key = YOUR_UNIQUE_API_KEY
& vat_number = SE556656688001
```

This was a successful request, and the details below are included in the response:

### Request parameters

<ParamField query="api_key" type="String" required>

  The VAT number to validate.
