paypal-rest-sdk

问题 About 2-3 weeks ago I added PayPal payment processing to my site and it worked like a charm with no problems. Now I've come back to the project to tweak the code. I haven't touched the Paypal code that I finished 2-3 weeks ago, and I tried to pay an invoice. I am currently running this in sandbox. The error I am getting is a duplicate transaction, duplicate invoice id. However each invoice ID is unique to each invoice created so I don't see how that could even be an issue (let alone I didn't

问题 I'm using the Paypal PHP REST API SDK, following exactly the samples provided by PayPal here to CREATE and CAPTURE an order.

问题 I am using PayPal iOS sdk to accept payment from user in my iOS app. I am using sandbox for testing. The payment is working fine, I am getting successful payment response along with Payment_ID.

问题 I'm using paypal-ruby-sdk to create recurring subscriptions by credit cards. When I create subscription plan, I set transaction(setup_fee) fee to zero. So paypal sandbox returns webhooks and the transaction fee is paid to PayPal according to their transaction fee rules. But I'm not sure who pays the fee to PayPal. I want a seller to pay the fee. The below code shows subscription plan creation I wrote: plan = Plan.new({ :name => self.unique_key, :description => self.title, :type => 'fixed',

问题 In my Dev environment, I can correctly use the Rest API to the sandbox site: $sdkConfig = array( "mode" => 'sandbox' ); $cred = new OAuthTokenCredential( $SANDBOX_clientId, $SANDBOX_clientSecret ); $access_token = $cred->getAccessToken($sdkConfig); When using the same code with Live Keys and a verified Live account: $sdkConfig = array( "mode" => 'live' ); $cred = new OAuthTokenCredential( $LIVE_clientId, $LIVE_clientSecret ); $access_token = $cred->getAccessToken($sdkConfig); I get this error

问题 I'm using paypal's REST API for digital transaction on my website. I have it all setup and working and have been able to successfully accept payments from a few users and give them their digital product. However, as of yet PayPal sees the transactions as if they were for physical items. I didn't find anything in the REST documentation regarding marking a transaction as digital. An example of one of my requests for the payment looks like this: { "intent": "sale", "redirect_urls": { "return_url

问题 I am trying to incorporate a member subscription on my website using the paypalrestsdk with python in a django application. I understand that I need to do the following: Set up a BillingPlan for each type of subscription (ie. a monthly plan for $10 a month and a yearly plan for $100 a month) Create a BillingAgreement, which (based on the user choice of billing plan) redirects the user to approve the agreement and which returns the agreement object which will give me the ability to access the
