How to check Billing Agreement is active or cancel?

问题

I am using Reference Transaction API in PayPal and not sure whether Billing Agreement is active or not while billing. I would like to know in advance if Billing Agreement is cancelled.

I am wondering to have callback call on Billing agreement cancel call.

回答1:

to check the status of a Billing Agreement you can use the BAUpdate API (NVP: METHOD=BillAgreementUpdate).

Normally this API is used to delete a Billing Agreement, but if you use it without the BillingAgreementStatus field, it returns the current status of Billing Agreement, allowing you to know if a Billing Agreement is still valid or not.

In fact if a Billing Agreement is no longer valid, Paypal will respond with an errorcode 10201 "Billing Agreement was cancelled"
