# Enable mobile notifications in user metadata

`PATCH https://api.cryptohopper.com/v1/user/usermetadata`

Part of [Users](https://www.cryptohopper.com/api-documentation/api-reference/users.md) in the Cryptohopper API reference.

Sets mobile_notifications to 1 in the user's metadata. It takes no input.

OAuth scope: `user`

The stored metadata is replaced by {"mobile_notifications": 1}, so any other metadata keys are removed.
