# Enable validation for a schema
Deprecated: Use \[Schema Validation API](https://developers.cloudflare.com/api/resources/schema\_validation/) instead.
PATCH/zones/{zone\_id}/api\_gateway/user\_schemas/{schema\_id}
Activates schema validation for an uploaded OpenAPI schema. Requests to matching endpoints will be validated against the schema definitions. Deprecated; use `/zones/{zone_id}/schema_validation/schemas/{schema_id}` instead.

The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key.
**Example:**X-Auth-Email: user@example.com
The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys.
