# Subscribed Event resource

With this API the user can perform CRUD operations on an Event associated with a Subscription.

With the Subscribed Event API you can:

* Add an existing event type to a subscription
* Get all events associated with a subscription
* Update an event on a subscription
* Delete an event on a subscription

## SubscribedEvent Properties

```json
{"type":"object","refName":"events.v1.subscription.subscribed_event","modelName":"events_v1_subscription_subscribed_event","properties":{"account_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^AC[0-9a-fA-F]{32}$","nullable":true,"description":"The unique SID identifier of the Account."},"type":{"type":"string","nullable":true,"description":"Type of event being subscribed to."},"schema_version":{"type":"integer","default":0,"description":"The schema version that the Subscription should use."},"subscription_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^DF[0-9a-fA-F]{32}$","nullable":true,"description":"The unique SID identifier of the Subscription."},"url":{"type":"string","format":"uri","nullable":true,"description":"The URL of this resource."}}}
```

## Add an Event Type

`POST https://events.twilio.com/v1/Subscriptions/{SubscriptionSid}/SubscribedEvents`

This endpoint adds an existing event type to a particular subscription. It is possible to specify the version of the schema to use for the given event type. Otherwise the last available schema version will be used for the added event type.

### Path parameters

```json
[{"name":"SubscriptionSid","in":"path","description":"The unique SID identifier of the Subscription.","schema":{"type":"string","minLength":34,"maxLength":34,"pattern":"^DF[0-9a-fA-F]{32}$"},"required":true}]
```

### Request body parameters

```json
