Invoking list-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:list-users with the function ARN from the management console.

  1. Run

    aws lambda invoke \
    --function-name arn:aws:lambda:ap-southeast-1:971422684006:function:list-users \
    response.json

  2. If the terminal shows:

    {
    "StatusCode": 200,
    "ExecutedVersion": "$LATEST"
}

    You have successfully invoked a Lambda function with AWS CLI.

  3. Check the Lambda function response payload

    cat response.json

    {"statusCode": 200, "headers": {"Content-Type": "application/json", "Access-Control-Allow-Origin": "*"}, "body": "{\"users\": [{\"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\"}, {\"updated_at\": \"2025-05-14T10:07:29\", \"created_at\": \"2025-05-14T10:07:29\", \"id\": \"a3127179-6ba4-4c3b-855a-4f65d4ee6345\", \"email\": \"nguyenvancanh@gmail.com\", \"name\": \"Nguyen Van Canh\"}, {\"updated_at\": \"2025-05-14T10:07:51\", \"created_at\": \"2025-05-14T10:07:51\", \"id\": \"e1f0cca8-cd19-4d8b-9124-70a63c351e3a\", \"email\": \"nguyenvanem@gmail.com\", \"name\": \"Nguyen Van Em\"}, {\"updated_at\": \"2025-05-14T10:07:15\", \"created_at\": \"2025-05-14T10:07:15\", \"id\": \"bb15f9cb-1379-4783-9f6f-23616d633d2a\", \"email\": \"nguyenvanbinh@gmail.com\", \"name\": \"Nguyen Van Binh\"}]}"}%

    You should see the users you created in previous step.

  4. [Optional] The response payload is in JSON, you can use jq to have a pretty print of it

    cat response.json | jq

    {
  "statusCode": 200,
  "headers": {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin": "*"
  },
  "body": "{\"users\": [{\"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\"}, {\"updated_at\": \"2025-05-14T10:07:29\", \"created_at\": \"2025-05-14T10:07:29\", \"id\": \"a3127179-6ba4-4c3b-855a-4f65d4ee6345\", \"email\": \"nguyenvancanh@gmail.com\", \"name\": \"Nguyen Van Canh\"}, {\"updated_at\": \"2025-05-14T10:07:51\", \"created_at\": \"2025-05-14T10:07:51\", \"id\": \"e1f0cca8-cd19-4d8b-9124-70a63c351e3a\", \"email\": \"nguyenvanem@gmail.com\", \"name\": \"Nguyen Van Em\"}, {\"updated_at\": \"2025-05-14T10:07:15\", \"created_at\": \"2025-05-14T10:07:15\", \"id\": \"bb15f9cb-1379-4783-9f6f-23616d633d2a\", \"email\": \"nguyenvanbinh@gmail.com\", \"name\": \"Nguyen Van Binh\"}]}"
}
