# Amazon Transcribe Medical and interface VPC endpoints (AWS PrivateLink)
<a name="med-vpc-interface-endpoints"></a>

You can establish a private connection between your VPC and Amazon Transcribe Medical by creating an *interface VPC endpoint*. Interface endpoints are powered by [AWS PrivateLink](https://aws.amazon.com/privatelink), a technology that enables you to privately access Amazon Transcribe Medical APIs without an internet gateway, NAT device, VPN connection, or Direct Connect connection. Instances in your VPC don't need public IP addresses to communicate with Amazon Transcribe Medical APIs. Traffic between your VPC and Amazon Transcribe Medical does not leave the Amazon network. 

Each interface endpoint is represented by one or more [Elastic Network Interfaces](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html) in your subnets. 

For more information, see [Interface VPC endpoints (AWS PrivateLink)](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html) in the *Amazon VPC User Guide*. 

## Considerations for Amazon Transcribe Medical VPC endpoints
<a name="med-vpc-endpoint-considerations"></a>

Before you set up an interface VPC endpoint for Amazon Transcribe Medical, ensure that you review [Interface endpoint properties and limitations](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#vpce-interface-limitations) in the *Amazon VPC User Guide*. 

Amazon Transcribe Medical supports making calls to all of its API actions from your VPC. 

## Creating an interface VPC endpoint for Amazon Transcribe Medical
<a name="med-vpc-endpoint-create"></a>

You can create a VPC endpoint for the Amazon Transcribe Medical service using either the AWS Management Console or the AWS CLI. For more information, see [Creating an interface endpoint](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#create-interface-endpoint) in the *Amazon VPC User Guide*.

For batch transcription in Amazon Transcribe Medical, create a VPC endpoint using the following service name: 
+ com.amazonaws.{{us-west-2}}.transcribe 

For streaming transcription in Amazon Transcribe Medical, create a VPC endpoint using the following service name: 
+ com.amazonaws.{{us-west-2}}.transcribestreaming 

If you enable private DNS for the endpoint, you can make API requests to Amazon Transcribe Medical using its default DNS name for the AWS Region, for example, `transcribestreaming.us-east-2.amazonaws.com`. 

For more information, see [Accessing a service through an interface endpoint](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#access-service-though-endpoint) in the *Amazon VPC User Guide*.

## Creating a VPC endpoint policy for Amazon Transcribe Medical streaming
<a name="med-vpc-endpoint-policy"></a>

You can attach an endpoint policy to your VPC endpoint that controls access to Amazon Transcribe Medical. The policy specifies the following information:
+ The principal that can perform actions.
+ The actions that can be performed.
+ The resources on which actions can be performed.

For more information, see [Controlling access to services with VPC endpoints](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-endpoints-access.html) in the *Amazon VPC User Guide*. 

**Example: VPC endpoint policy for Amazon Transcribe Medical streaming transcription actions**  
The following is an example of an endpoint policy for streaming transcription in Amazon Transcribe Medical. When attached to an endpoint, this policy grants access to the listed Amazon Transcribe Medical actions for all principals on all resources.

```
{
   "Statement":[
      {
         "Principal":"*",
         "Effect":"Allow",
         "Action":[
            "{{transcribe}}:{{StartMedicalStreamTranscription}}",
         ],
         "Resource":"*"
      }
   ]
}
```

**Example: VPC endpoint policy for Amazon Transcribe Medical batch transcription actions**  
The following is an example of an endpoint policy for batch transcription in Amazon Transcribe Medical. When attached to an endpoint, this policy grants access to the listed Amazon Transcribe Medical actions for all principals on all resources.

```
{
   "Statement":[
      {
         "Principal":"*",
         "Effect":"Allow",
         "Action":[
            "{{transcribe:StartMedicalTranscriptionJob}}"
         ],
         "Resource":"*"
      }
   ]
}
```

## Shared subnets
<a name="med-vpc-shared-subnets"></a>

You cannot create, describe, modify, or delete VPC endpoints in subnets that are shared with you. However, you can use the VPC endpoints in subnets that are shared with you. For information about VPC sharing, see [Share your VPC with other accounts](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-sharing.html#vpc-sharing-service-behavior) in the Amazon Virtual Private Cloud guide.
