Invoking create-user function

Replace ap-southeast-1 with your AWS region, 971422684006 with your AWS account number, or replace the whole arn:aws:lambda:ap-southeast-1:971422684006:function:create-user with the function ARN from the management console.

  1. Run

    aws lambda invoke \
    --function-name arn:aws:lambda:ap-southeast-1:971422684006:function:create-user \
    --cli-binary-format raw-in-base64-out \
    --payload '{ "email": "nguyenvandong@gmail.com", "name": "Nguyen Van Dong" }' \
    response.json

  2. Check the response

    cat response.json

    {"statusCode": 200, "headers": {"Content-Type": "application/json", "Access-Control-Allow-Origin": "*"}, "body": "{\"updated_at\": \"2025-05-14T10:07:42\", \"created_at\": \"2025-05-14T10:07:42\", \"id\": \"6c539686-de1c-4bef-85ef-f68a4b5aabe0\", \"email\": \"nguyenvandong@gmail.com\", \"name\": \"Nguyen Van Dong\"}"}%

  3. To verify that the user is updated, you can

    • Invoke list-users again.
    • Or use the DynamoDB console.
