Exercise 5: Create an Alias (AWS CLI) - Amazon Lex V1

End of support notice: On September 15, 2025, AWS will discontinue support for Amazon Lex V1. After September 15, 2025, you will no longer be able to access the Amazon Lex V1 console or Amazon Lex V1 resources. If you are using Amazon Lex V2, refer to the Amazon Lex V2 guide instead. .

An alias is a pointer to a specific version of a bot. With an alias you can easily update the version that your client applications are using. For more information, see Versioning and Aliases.To run the commands in this exercise, you need to know the region where the commands will be run. For a list of regions, see Model Building Quotas .

To create an alias (AWS CLI)

In the AWS CLI, get the version of the OrderFlowersBot bot that you created in Exercise 4: Publish a Version (AWS CLI).


aws lex-models get-bot \
    --region region \
    --name OrderFlowersBot \
    --version-or-alias version > OrderFlowersBot_V5.json

In a text editor, open OrderFlowersBot_v5.json. Find and record the version number.

In the AWS CLI, create the bot alias:


aws lex-models put-bot-alias  \
    --region region \
    --name PROD \
    --bot-name OrderFlowersBot \
    --bot-version version

The following is the reponse from the server:

{
    "name": "PROD",
    "createdDate": timestamp,
    "checksum": "checksum",
    "lastUpdatedDate": timestamp,
    "botName": "OrderFlowersBot",
    "botVersion": "1"
}}
