You can call this operation to create or update a specified asynchronous invocation configuration of a function in a service.

  • If the function does not have the asynchronous invocation configuration, you can call the PutFunctionAsyncInvokeConfig operation to create the configuration.
  • If the function has the asynchronous invocation configuration, you can call the PutFunctionAsyncInvokeConfig operation to update the configuration with the configuration items that are specified in the request. Items that are not specified in the request remain unchanged.
