Hello,
I am trying to achieve a multi-account architecture provisioning through terraform.
Example
Account - A (user John)
Account - B (having a role name admin which has the policy to SNS service)
Cross account has been setup and John is able to switch to Account-B through crossaccount role.
Terraform Provider
provider “aws” {
region = “us-east-2”
profile = “John”
assume_role {
role_arn = "arn:aws:iam::<Account-B-id>:role/cross-account-role"
session_name = "Terraform"
}
}
now I need to create a SNS topic in the Account-B and need the topic ARN to update a resource in Account-A(user: John).
Could you please suggest a terraformic 
way to create the resource in target account and get the value of that resource to perform further action in source account.
Thanks
