# Creating a channel membership for an AppInstanceBot for Amazon Chime SDK messaging
<a name="channel-membership"></a>

Once you create the AppInstanceBot, you add it as a member to a new or existing channel. For more information see [CreateChannel](https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_messaging-chime_CreateChannel.html) and [ CreateChannelMembership](https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_messaging-chime_CreateChannelMembership.html) in the *Amazon Chime SDK messaging API* documentation.

The following example shows how to use the AWS CLI to create a channel and add an `AppInstanceBot` as a member.

```
aws chime-sdk-messaging create-channel \
--chime-bearer caller_app_instance_user_arn \
--app-instance-arn app_instance_arn \
--name channel_name \
--member-arns '[
   "app_instance_bot_arn"
]'
```

The following example shows how to use the AWS CLI to add an `AppInstanceBot` to an existing channel.

```
aws chime-sdk-messaging create-channel-membership \
--chime-bearer caller_app_instance_user_arn \
--channel-arn channel_arn \
--member-arn app_instance_bot_arn
```
