# Upload WhatsApp Template Media Files

You can use the WhatsApp Template Management API to upload files when your template components need a media handle for an image, video, or document header. You can use this API version when authenticating requests with an Insider One API key.

> [!NOTE]
> All examples below use sample data and payloads for documentation purposes only. Before going live, replace all template names, languages, components, and media handles with values specific to your own integration.

> [!WARNING]
> For the V1 template API, authenticate requests with `x-ins-auth-key` . Public examples below use the Gateway base URL so that your integration stays on a public entrypoint instead of calling internal services.

> [!WARNING]
> For this endpoint, only image, video, and document file types are supported.
