## Service-Specific Condition Keys

In addition to the global condition keys above, some services support their own condition keys, matching AWS's [per-service condition key reference](https://docs.aws.amazon.com/service-authorization/latest/reference/reference_policies_actions-resources-contextkeys.html):

- [EC2](/aws/services/ec2/#iam-condition-keys): `ec2:MetadataHttpTokens`, `ec2:Attribute/<AttributeName>`
- [RAM](/aws/services/ram/#iam-condition-keys): `ram:RequestedAllowsExternalPrincipals`

## IAM Condition Keys

When [IAM Policy Enforcement](/aws/developer-tools/security-testing/iam-policy-enforcement/) is enabled, LocalStack supports the following RAM-specific condition key, matching the behavior described in the [AWS condition keys reference](https://docs.aws.amazon.com/service-authorization/latest/reference/list_awsresourceaccessmanager.html#awsresourceaccessmanager-policy-keys):

- `ram:RequestedAllowsExternalPrincipals` &mdash; the `allowExternalPrincipals` value of a `CreateResourceShare` or `UpdateResourceShare` request, useful for restricting resource shares to principals within your organization.

For example, the following policy statement only allows creating or updating a resource share when it does not allow external principals:

```json
{
"Effect": "Allow",
"Action": ["ram:CreateResourceShare", "ram:UpdateResourceShare"],
"Resource": "*",
"Condition": {
"Bool": { "ram:RequestedAllowsExternalPrincipals": "false" }
}
}
```
