The User Binding resource provides access to [Binding resources](/docs/chat/rest/binding-resource) that is scoped to a single [User](/docs/chat/rest/user-resource).

## Binding Properties

Each User Binding resource contains these properties.

## Fetch a User Binding resource

`GET https://chat.twilio.com/v2/Services/{ServiceSid}/Users/{UserSid}/Bindings/{Sid}`

The `{UserSid}` value can be either the `sid` or the `identity` of the User resource to fetch the User Binding resource from.
