+## Pending Order Timeout configuration
+By default, an order remains in PAYMENT_PENDING status in order management for 1 hour and it is configured in dynamic order process defintiion file. 
+Based on which extension you are using (fulfillment or ordermanangement) timeout value can be updated in corresponding order-process.xml file. 
+
+For example, following 2 files have 60 mins configuration under waitForAdyenPendingPayment process with delay value=PT60M
+
+Fulfillment extension file - resources/adyenv6fulfilmentprocess/process/order-process.xml
+
+OrderManagement extension file - resources/adyenv6ordermanagement/process/order-process.xml
+```
+<wait id="waitForAdyenPendingPayment" then="checkPendingOrder">
+        <event>AdyenPaymentResult</event>
+        <timeout delay="PT60M" then="checkPendingOrder"/>
+    </wait>

 ## PayPal configuration
 This plugin uses Adyen's Checkout Component for PayPal payments. To use that in a live environment, a PayPal Merchant Id is required [(check here how to get one)](https://docs.adyen.com/payment-methods/paypal/web-component#get-your-paypal-merchant-id). This id has to be provided when adding your Adyen credentials to the BaseStore via the backoffice [(installation step 5)](#installation).
