1. API Description

Domain name for API request:

This API is used to replicate a function. You can store the replicated function in a specified Region and Namespace.
Note: This API does not replicate the following objects or attributes of the function:

  2. Versions other than $LATEST
  3. CLS target of the logs configured in the function

You can manually configure the function after replication as required.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
