    <p>I've a sandbox account with PayPal. I can retrieve the token via the api using curl on PHP, however processing a test card just returns null. Anyone see a problem with the code? Is this a known problem with the PayPal sandbox? The client in the below snippet are fabricated, however, as mentioned before, using my real credentials I can successfully make a call to retrieve the token. </p> <p>The PHP to generate the request: </p> <pre><code> &lt;?php class psPayPal { private $tokenUrl = 'https://api.sandbox.paypal.com/v1/oauth2/token'; private $paymentUrl = 'https://api.sandbox.paypal.com/v1/payments/payment'; private $client = 'dlkjasdfkja;skdjfaksdjfkajsdkfjaejkjefkekjakdjfaksjdfadjf;ja'; private $secret = 'klj;akjdfjeieiadfaldkjfelkajsdfkjaejeiejisadif;alkdsfj;kjjie'; private $token; private $tokenHandle; private $paymentHandle; public function __construct() { $this-&gt;tokenHandle = curl_init($this-&gt;tokenUrl); $this-&gt;buildTokenRequest(); } public function buildTokenRequest() { $header = array( 'Accept: application/json', 'Accept-Language: en_US' ); $user = $this-&gt;client . ':' . $this-&gt;secret; $data = 'grant_type=client_credentials'; curl_setopt($this-&gt;tokenHandle, CURLOPT_HTTPHEADER, $header); curl_setopt($this-&gt;tokenHandle, CURLOPT_USERPWD, $user); curl_setopt($this-&gt;tokenHandle, CURLOPT_POSTFIELDS, $data); curl_setopt($this-&gt;tokenHandle, CURLOPT_RETURNTRANSFER, true); $this-&gt;commitTokenRequest(); } public function commitTokenRequest() { $response = json_decode(curl_exec($this-&gt;tokenHandle)); $this-&gt;token = $response-&gt;access_token; curl_close($this-&gt;tokenHandle); } public function buildPaymentRequest($cost = '', $description = '') { $this-&gt;paymentHandle = curl_init($this-&gt;paymentUrl); $header = array( 'Accept: application/json', 'Accept-Language: en_US', 'Authorization:Bearer ' . $this-&gt;token ); $data = array( 'intent' =&gt; 'sale', 'payer' =&gt; array( 'payment_method' =&gt; 'credit_card', 'funding_instruments' =&gt; array( array( 'credit_card' =&gt; array( 'number' =&gt; '5500005555555559', 'type' =&gt; 'mastercard', 'expire_year'=&gt; '2018', 'cvv2'=&gt; '111', 'first_name'=&gt; 'Joe', 'last_name' =&gt; 'Shopper' ) ) ) ), 'transactions' =&gt; array( array( 'amount' =&gt; array( 'total' =&gt; '39.54', 'currency' =&gt; 'USD' ), 'description' =&gt; 'This is my descrription for hats' ) ) ); $d = json_encode($data); curl_setopt($this-&gt;paymentHandle, CURLOPT_HTTPHEADER, $header); curl_setopt($this-&gt;paymentHandle, CURLOPT_POSTFIELDS, $d); curl_setopt($this-&gt;paymentHandle, CURLOPT_RETURNTRANSFER, true); $this-&gt;commitPaymentRequest(); } public function commitPaymentRequest() { $response = json_decode(curl_exec($this-&gt;paymentHandle)); var_dump($response); curl_close($this-&gt;paymentHandle); } } ?&gt; </code></pre> <p>I've tried with a variety of options, although I believe the code above to be complete. I've also validated the jSON I'm sending with JSON Lint. The JSON follows: </p> <pre><code>{ "intent": "sale", "payer": { "payment_method": "credit_card", "funding_instruments": [ { "credit_card": { "number": "5500005555555559", "type": "mastercard", "expire_year": "2018", "cvv2": "111", "first_name": "Joe", "last_name": "Shopper" } } ] }, "transactions": [ { "amount": { "total": "39.54", "currency": "USD" }, "description": "This is my descrription for hats" } ] </code></pre> <p>}</p> <p>Any suggestions greatly appreciated! </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
