# Types

> Manage types for generic token schemas

Types define schemas for generic token payloads. They enable validation and filtering for generic tokens
and provide structure for otherwise flexible payloads.

## Overview

Types are schema definitions that can be applied to
[Generic Tokens](/products/guardian/tokens/generic-tokens). They describe the expected structure of the payload
and are enforced when generic tokens are created or updated.

## Key features

* **Schema definition**: Define the structure of generic token payloads.
* **Validation**: Ensure payloads match the defined schema.
* **Filtering**: Query generic tokens based on schema-defined fields.
* **Type safety**: Enforce consistent data structures across tokens.

## Example use cases

* SEPA credential schemas.
* API key metadata structures.
* Custom authentication token formats.
* Any structured sensitive data that benefits from validation and filtering.
