PayPal notify-URL not anymore in createBilligAgreementToken requests?

[Martin_Strube]

I use the PayPal API to get Billing Agreements via

/billing-agreements/agreement-tokens

Anyhow I wonder where the parameter for the PayPal notification function is now. Recently the request Body looked like this

{
  "description": "Billing Agreement",
  "payer": {
      "payment_method": "PAYPAL"
},
  "plan": {
  "type": "MERCHANT_INITIATED_BILLING",
  "merchant_preferences": {
    "return_url": "https://example.com/return",
    "cancel_url": "https://example.com/cancel",
    "notify_url": "https://example.com/notify",
    "accepted_pymt_type": "INSTANT",
    "skip_shipping_address": false
 } 
}
}

However the API looks totally different now. Do I have to switch to a new API now that looks like this:

/v1/payments/billing-agreements

What happende with the notifiy_url in my actuall calls? Doesn't it exist anymore? How to get callbacks if a customer cancels his BillingAgreement?

Do I have to use the webhooks now? https://developer.paypal.com/docs/api/webhooks/v1/
