한국에서 페이팔 결제 연동 테스트
페이팔 가맹점입니다. 쇼핑몰 구축하고 페이팔 checkout 결제연동 중입니다. access_token 으로 Make REST API calls 를 하여 id, status, links를 받고 links에서 approve주소를 redirect해 결제창을 띠운 후 sandbox personal account로 결제를 진행하고 있는데 continue가 되지 않습니다. 결제창까지 떴는데 최종 결제가 이루어지지 않고 그냥 그 결제창으로 되돌아가는 이유가 무언가요?

[WHY?] I have a situation, not solved. I still have tried workaround with no success, same loop returning to same form in the PayPal website. I see the button is CONTINUE instead of PAY NOW. Is it maybe a clue?
search key word, paypal continue button redirect same address https://stackoverflow.com/questions/64346150/paypal-authorization-link-redirects-user-nowhere-and-keeps-a-loop-in-the-same-pa pay now버튼이 보이지 않고 continue 버튼이 보인다. 그리고 그 버튼이 계속된다. 결제는 되지 않고 왜지? 0 If you are redirecting the user over to the approval_url, then your original API request should have included a return_url, so PayPal knows where to return the customer. A return from the approval is required, so that you can capture the order, otherwise there will be no payment. The best integration uses no redirects whatsoever. In place of sending the browser to the approval URL, all you need is to create the order and get back its id value. Then use that to show a button that gives an in-context checkout experience, keeping your site loaded in the background (no redirect away). Once the buyer gives their approval, you'll then do the API call to capture the order. Here is the demo code: https://developer.paypal.com/demo/checkout/#/pattern/server It's actually very simple/straightforward, most of the stuff at the end is some pointers about post-capture error handling 답을 주긴 했다만 도움이 안된다. auto return 기능을 살펴보자 밥먹고와서 혹시 Return URL- Users are redirected to this URL after live transactions.

Webhook is the hint for CONTINUE LOOP PROBLEM
REST APIs Webhooks are HTTP callbacks that receive notification messages for events. To create a webhook in PayPal, merchants configure a webhook listener and subscribe it to events. A webhook listener is a server that listens at a specific URL for incoming HTTP POST notification messages that are triggered when events occur.

Authorized and captured payments Batch payouts Billing plans and agreements Log in with PayPal Disputes Checkout buyer approval Invoicing Marketplaces and Platforms Merchant onboarding Orders Payment orders Referenced payouts Sales Subscriptions Vault Matching CHECKOUT.ORDER.APPROVED with PAYMENT.CAPTURE.COMPLETED Options djslim djslim Contributor Contributor Posted on ‎Apr-04-2020 08:07 PM Hi, I'm completely new to the PayPal API. I'm using the smart button with a web hook to capture the payment & shipping information. I thought I'd get the shipping info with the event CHECKOUT.ORDER.APPROVED then when I get the PAYMENT.CAPTURE.COMPLETED event I'll be sure the payment is fully processed. I noticed that the transaction ID for both are different. so I have no way of matching the two. Is there a way to match the two that I'm missing? Or can I just assume CHECKOUT.ORDER.APPROVED is enough to trust that everything is good and ignore PAYMENT.CAPTURE.COMPLETED? We would always recommend waiting for the "Payment.Capture.Completed" webhook for each transaction. The webhook for "Checkout.Order.Approved" was actually intended to be used to notify your system to attempt Payment Capture. In other words, some capture immediately and really don't need the Approved webhook since just the Completed one would suffice. But some choose to authorize, then capture later, checking to make sure they got an Approved webhook before initiating the capture. That's just a glimpse into the original intent. I believe you can add your own order id called an "invoice_id". You can pass this in the "purchase_units" object when creating the transaction. Then, when you receive the checkout.order.approved webhook, you can look at the details of the transaction to find the invoice_id. Then, when capturing the transaction, that same invoice ID will be attributed to the captured ID as well. I hope that helps! Options IDislikThisGame IDislikThisGame Member Member ‎Aug-01-2021 11:15 AM This is the reality of PayPal in 2021. You cant pass data to PAYMENT.CAPTURE.COMPLETED for whatever reason and you can't match CHECKOUT.ORDER.APPROVED that contains the relevant data to the right COMPLETED. Using PayPal feels like fighting against PayPal not like using it Options MarcoT999 MarcoT999 Contributor Contributor ‎Sep-23-2021 01:29 PM This is a serious problem for us. There is no way to attribute `CHECKOUT.ORDER.APPROVED` with a `PAYMENT.CAPTURE.COMPLETED` since anything within the purchase_units don't show up in the latter webhook. Aaron... help us out man. -Aaron I did find a way by analyzing the JSON payload in the webhook. I was able to match the checkout with the successful payment using: req.body.resource.supplementary_data.related_ids.order_id

After you configure a listener.. WHAT MEANS? [HOw to use the webhooks simulator] [The PayPal REST APIs can use webhooks for event notification.]

[?]PayPal-Request-Id : 이것은 임의로 만들어 보내고 서버에 저장해서 사용할 수 있는건가?
PayPal-Request-Id Optional. Contains a unique user-generated ID that the server stores for a period of time. Use this header to enforce idempotency on REST API POST calls. You can make these calls any number of times without concern that the server creates or completes an action on a resource more than once. You can retry calls that fail with network timeouts or the HTTP 500 status code. You can retry calls for as long as the server stores the ID. For example, a user calls refund captured payment with the PayPal-Request-Id header that contains a unique user-provided ID. The user can make the call again with the same ID in the PayPal-Request-Id header for up to 45 days because the server stores this ID for this long for this call. If the initial call fails with the HTTP 500 status code but the server has already refunded the payment, the caller does not need to worry that the server will refund the payment again.

Auto Return Page https://www.paypal.com/us/smarthelp/article/how-do-i-use-paypal's-auto-return-feature-to-redirect-customers-back-to-my-website-faq3651
How do I use PayPal's Auto Return feature to redirect customers back to my website? *The feature is only available for Business accounts. The Auto Return feature for PayPal Payments Standard redirects the buyer back to your website after completing the payment. This feature replaces the PayPal-hosted Payment Done page with a page hosted on your website. Here's how to enable Auto Return: Click Settings. Click Website payments under "Product & Services" on the left of the page. Click Update next to "Website preferences." Click On under "Auto return." In the Return URL field, enter the URL where you want to send your payer after payment is complete. The Return URL is applied to all Auto Return payments unless otherwise specified within the payment button or link. Click Save. When you specify a Return URL for Auto Return, the target page must meet the following requirements of the PayPal User Agreement. The text must help the buyer understand that the payment was made and the transaction was completed. The text must explain that the buyer will receive an email containing details about the payment transaction. The page must provide a good user experience for your customers. This includes, but is not limited to: Visual consistency with the rest of your merchant site. No request for any PayPal account information details. Example: "Thank you for your payment. Your transaction has completed, and we are sending you an email containing the receipt for your purchase. Click here to log in to your account and view details of this transaction."

PAYOUTS API
Use the Payouts API to make payments to multiple PayPal or Venmo recipients. The Payouts API is a fast, convenient way to send commissions, rebates, rewards, and general disbursements. You can send up to 15,000 payments per call. If you integrated the Payouts API before September 1, 2017, you receive transaction reports through Mass Payments Reporting. Otherwise, view reports from your PayPal Business account. The Payouts API uses the ISO 8601 Internet date and time format.
