# Service Binding Resource

A Binding resource in Twilio Conversations represents a Push notification subscription for a [User](/docs/conversations/api/user-resource) within their Service instance. Bindings are unique per Service instance, User identity, device, and notification channel (such as APNS, GCM, FCM).

## Binding Properties

Each Binding resource has the following properties:

```json
{"type":"object","refName":"conversations.v1.service.service_binding","modelName":"conversations_v1_service_service_binding","properties":{"sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^BS[0-9a-fA-F]{32}$","nullable":true,"description":"A 34 character string that uniquely identifies this resource."},"account_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^AC[0-9a-fA-F]{32}$","nullable":true,"description":"The unique ID of the [Account](/docs/iam/api/account) responsible for this binding."},"chat_service_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^IS[0-9a-fA-F]{32}$","nullable":true,"description":"The SID of the [Conversation Service](/docs/conversations/api/service-resource) the Binding resource is associated with."},"credential_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^CR[0-9a-fA-F]{32}$","nullable":true,"description":"The SID of the [Credential](/docs/conversations/api/credential-resource) for the binding.

Can be: `apn`, `gcm`, `fcm`, or `twilsock`.  See [push notification configuration](/docs/chat/push-notification-configuration) for more info.","refName":"service_binding_enum_binding_type","modelName":"service_binding_enum_binding_type"},"message_types":{"type":"array","nullable":true,"description":"The [Conversation message types](/docs/chat/push-notification-configuration#push-types) the binding is subscribed to.","items":{"type":"string"}},"url":{"type":"string","format":"uri","nullable":true,"description":"An absolute API resource URL for this binding."}}}
