Create subscription (by alias)

onesignal_id can be used as a special alias_label, with the UUID as the alias_id.

At minimum, a device type must be provided in the request when creating a new subscription. For example, for an iOS push subscription, it would look like the following:

{
  "subscription": {
    "type": "iOSPush"
  }
}

A subscription is uniquely identified by its device type and token pair. If the given (type, token) pair exists on an existing subscription, that subscription will be transferred to this User.

Note: You can also create and modify existing subscriptions associated with a user. Refer to the create user documentation here.

Response codes:

• 201: a new Subscription was created
