POPaypal says my CancelURL is invalid?
text
Body
copied!<p>I'm creating a site and am just adding in payments.<br> I'm using the <a href="https://github.com/paypalx/SDKs/tree/master/Merchant/merchant-php-sdk" rel="nofollow">Paypal SDK</a> and have setup my <code>SetExpressCheckout()</code>.</p> <p>Here is the response,</p> <pre><code>object(SetExpressCheckoutResponseType)[72] public 'Token' => null public 'Timestamp' => string '2012-08-23T15:21:15Z' (length=20) public 'Ack' => string 'Failure' (length=7) public 'CorrelationID' => string 'e0278e8e18b4f' (length=13) public 'Errors' => object(ErrorType)[78] public 'ShortMessage' => string 'Transaction refused because of an invalid argument. See additional error messages for details.' (length=94) public 'LongMessage' => string 'CancelURL is invalid.' (length=21) public 'ErrorCode' => string '10472' (length=5) public 'SeverityCode' => string 'Error' (length=5) public 'ErrorParameters' => null public 'Version' => string '93.0' (length=4) public 'Build' => string '3556406' (length=7) </code></pre> <p>I'm not sure what's up. My <code>CancelURL</code> looks like, <code>urlencode('https://www.example.com/users/account/');</code>. I've included the trailing slash, which some people think can cause it to be invalid. </p> <p>The only thing that I can think of is that because my site isn't online anywhere, that Paypal can't reach the page. I have created a dummy page and uploaded it into <code>/users/account/</code> on the server so it's reachable and still nothing. I also have an entry in my <code>etc/hosts</code> to route <code>example.com</code> traffic to my localhost which worked fine for my Facebook Auth bits.</p> <p>Anyone have any ideas on what the restrictions are for a CancelURL and why Paypal is kicking my request?</p> <hr> <p><strong>Request generation</strong> </p> <pre><code>$int = new PayPalAPIInterfaceServiceService(); $amount = new BasicAmountType(); $amount->currencyID = CakeSession::read('Locale.currency'); $amount->value = Configure::read('Subscription.price.'.CakeSession::read('Locale.shortname')); $req_details_type = new SetExpressCheckoutRequestDetailsType(); $req_details_type->OrderTotal = $amount; $req_details_type->ReturnURL = urlencode('https://www.example.com/paypal/getExpressCheckoutDetails'); $req_details_type->CancelURL = urlencode('https://www.example.com/users/account/'); $req_details_type->MaxAmount = $amount; $req_details_type->OrderDescription = "Monthly subscription to Example.com Pro"; $req_details_type->ReqConfirmShipping = 0; $req_details_type->NoShipping = 1; $req_details_type->LocaleCode = CakeSession::read('Locale.shortname') == 'usa'? 'US' : 'GB'; $req_details_type->PaymentAction = 'Authorization'; $req_details_type->BuyerEmail = AuthComponent::user('email'); $req_details_type->BrandName = urlencode("Example.com"); $req_type = new SetExpressCheckoutRequestType(); $req_type->SetExpressCheckoutRequestDetails = $req_details_type; $req = new SetExpressCheckoutReq(); $req->SetExpressCheckoutRequest = $req_type; $response = $int->SetExpressCheckout($req); var_dump($response); </code></pre>
