+#### Adaptive Payments
+
+To use adaptive payments, you must set the provider to use Adaptive Payments:
+
+```
+PayPal::setProvider('adaptive_payments');
+```
+
+<a name="usage-adaptive-pay"></a>
+* **Pay**
+
+```

+
+// The above API call will return the following values if successful:
+// 'responseEnvelope.ack', 'payKey', 'paymentExecStatus'
+
+```
+
+Next, you need to redirect the user to PayPal to authorize the payment
+
+```
+$redirect_url = PayPal::getProvider()->getRedirectUrl('approved', $response['payKey']);
+
+return redirect($redirect_url);
