to access the Pricing service in your account. We use 3rd party roles for this.
(Note: self-hosted WebhookDB customers have other auth methods available).

Here's how to do this from the AWS Console; you can do this via CDK or similar if you wish, too.

- Log into AWS
- Go to IAM
- Go to 'Policies' on the nav bar
- Create a policy like this (name it whatever you want, we'll use "WebhookDBPricing"):

{
  "Version": "2012-10-17",
  "Statement": [
      {
          "Sid": "WebhookDBPricing",
          "Effect": "Allow",
          "Action": [
              "pricing:DescribeServices",
              "pricing:ListPriceLists",
              "pricing:GetAttributeValues",
              "pricing:GetPriceListFileUrl",
              "pricing:GetProducts"
          ],
          "Resource": "*"
      }
  ]
}

- Go to 'Roles' in the nav bar.
- Choose 'AWS Account' as the entity type.
- Choose 'Another AWS Account' and enter our Account ID: #{Webhookdb::AWS.}
- Check 'Require an external ID'. Choose whatever you wish. Here's one to try: WHDBPR-#{SecureRandom.hex(8)}
- Go to the next page. Choose the policy created earlier (WebhookDBPricing).
- Go to the next page. Give the role a name like 'WebhookDBPricing'.
- Create the role.
- Find the newly created role, and copy the ARN and External ID.
