Get AWS Account ID from Boto

amazon-web-services, boto3, python

Solution

Thanks to @louahola for the improvement on my initial answer.

This will get you the Account ID for your key pair:

import boto3

sts = boto3.client(
    "sts", aws_access_key_id=ACCESS_KEY, aws_secret_access_key=SECRET_KEY,
)
account_id = sts.get_caller_identity()["Account"]

If you are running on an EC2 instance with IAM role-based permissions or any of boto3's other credential options, you can do this even easier:

import boto3

account_id = boto3.client("sts").get_caller_identity()["Account"]

Problem

I have an AWS_ACCESS_KEY_ID and an AWS_SECRET_KEY. These are active credentials, so they belong to an active user, who belongs to an AWS Account. How, using Boto3, do I find the ID of this AWS Account?
