# Create an extension

> Creates the extension.
 The extensions API supports two types of usage patterns.
 A). Specify a `download_url`, http or https URL,  where the extension is currently hosted. This will result in extension being copied to elastic repository.
 B). Create only the extension metadata using the `POST` endpoint and then use `PUT` to upload the extension file. Leave the `download_url` unspecified in this case.
