PayPal 订阅集成 | 与捕获资金混淆

Question

I am currently working on a PayPal Subscription Integration for a client. But I had some issues with PayPal, do I need to capture the funds when the subscription is activated, and do I need to capture the funds every time the next billing cycle is hit? Or do I only need to do 1 of them?

Like, how does this work?

And how do I cancel a subscription when an error occurs when the user is trying to activate his subscription? Should I just cancel it using an API request from my server, or is there a function in the PayPal JS SDK (in the frontend) to cancel it? Since there is a method to actions.restart() restart the payment flow, but that is not what I want and doesn't work actually since that gives me an error again for some reason.

It's very confusing, the documentation also isn't helping me on that and PayPal's Community forums are kinda dead.

Thank you.

Answer 1

When a PayPal Subscription is approved by the payer, it will become active and bill (capture) automatically. This will be immediate if no start_date is specified.

There is no server-side activation and hence no need for an actions.restart() equivalent.

(An exception to this is if you override the application_context's user_action; this changes the verbiage to indicate you are going to show a review page, and do the activation with an API call)

Cancellations are done using API calls, not the JS SDK.
