1. API Description

Domain name for API request: scf.tencentcloudapi.com.

This API is used to create an alias for a function version. You can use the alias to mark a specific function version such as DEV/RELEASE. You can also modify the version pointed to by the alias at any time.
An alias must point to a master version and can point to an additional version at the same time. If you specify an alias when invoking a function, the request will be sent to the versions pointed to by the alias. You can configure the ratio between the master version and additional version during request sending.

A maximum of 20 requests can be initiated per second for this API.
