Deprecation notice: The /v1/payments/billing-agreements endpoints are deprecated. Use the /v1/billing/subscriptions
That is my solution, I had to implement a new function with the new api
class PayPalPaymentMethod:
#staticmethod
def get_billing_subscription(billing_agreement_id, paypal_mode, paypal_client_id, paypal_secret_id):
url = util.join_url('/v1/billing/subscriptions', billing_agreement_id)
api = Api({
'mode': paypal_mode,
'client_id': paypal_client_id,
'client_secret': paypal_secret_id
})
result = api.get(url)
return result
