Update a message template
Updates a template's `category` or `components`. A template can only be updated while it is **not yet approved** — once approved, delete and recreate it to make changes.
#### Permissions
The API token used to authenticate must have the following scope(s) enabled to make a successful request: _Numbers_.
[Learn more about API scopes](/docs/platform/your-signalwire-api-space).
Authentication
AuthorizationBasic
SignalWire Basic Authentication using Project ID and API Token.
The client sends HTTP requests with the Authorization header containing
the word Basic followed by a space and a base64-encoded string of project_id:token.
The project ID will be used as the username and the API token as the password.
Example:
```
Authorization: Basic base64(project_id:token)
```
