python - Get AWS Account ID from Boto

Question

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?

Answer 1

The AccountID can be grabbed from the get-caller-identity sts function. This returns an "Account" field:

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