+### Authorize & Capture Later
+
+In EveryPay, when the payment will be captured is configured at the account level. If you want to authorize a payment without capturing it, then you need a Merchant Account configured accordingly.
+
+To authorize a payment, simply substitue `purchase` and `completePurchase` methods with `authorize` and `completeAuthorize`. Then call `capture` to capture the funds.
+
+```php
+// Here, pass the payment array that we previously stored when creating the payment
+$gateway->authorize([
+        'amount' => $amount,
+        'paymentType' => PaymentType::CIT,
+    ])
+    ->setCardReference('previously stored card token')
+    // Set all the other parameters. See previous examples ...
+    ->send();
+
+// Redirect the user to 3DS confirmation as necessary.
+
+// When EveryPay redirects the user back, do this...
+// This won't capture the payment yet, but makes sure the authorization is successful.
+$authorizeResponse = $gateway->completeAuthorize()
+    ->setTransactionId($_GET['order_reference'])
+    ->setTransactionReference($_GET['payment_reference'])
+    ->send();
+
+// Hold on to this.. You'll use this reference to capture the payment.
+$paymentReference = $authorizeResponse->getTransactionReference();
+
+// When you're ready to capture, call:
+$response = $gateway->capture([
+  'amount' => $amount, // You can capture partially, or the whole amount.
+  'transactionReference' => $paymentReference,
+])->send();
+
+if ($response->isSuccessful()) {
+   // Payment captured!
+} else {
+  // Something went wrong!
+  // Check $response->getMessage();
