# Change Image Transformations C2PA setting

PATCH/zones/{zone\_id}/settings/transformations\_c2pa

C2PA (Coalition for Content Provenance and Authenticity) signing adds cryptographic metadata to images processed through Cloudflare Image Transformations, enabling verification of image authenticity and provenance.

##### Security

API Token

The preferred authorization scheme for interacting with the Cloudflare API. [Create a token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/).

**Example:**`Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY`

API Email + API Key

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.

**Example:**`X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194`
