+SearchOrders
+
+Search all Orders for a merchant and return either [Orders](#type-order) or [OrderEntries](#type-orderentry).  Note that details for orders processed with Square Point of Sale while in offline mode may not be transmitted to Square for up to 72 hours. Offline orders have a &#x60;created_at&#x60; value that reflects the time the order was originally processed, not the time it was subsequently transmitted to Square. Consequently, the SearchOrder endpoint might list an offline Order chronologically between online Orders that were seen in a previous request.  By default, SearchOrders will return all results for all of the merchant’s locations. When fetching additional pages using a &#x60;cursor&#x60;, the &#x60;query&#x60; must be equal to the &#x60;query&#x60; used to fetch the first page of results.
+
+### Example
+```javascript
+var SquareConnect = require('square-connect');
+var defaultClient = SquareConnect.ApiClient.instance;
+
+// Configure OAuth2 access token for authorization: oauth2
+var oauth2 = defaultClient.authentications['oauth2'];

-Charges a card represented by a card nonce or a customer&#39;s card on file.  Your request to this endpoint must include _either_:  - A value for the &#x60;card_nonce&#x60; parameter (to charge a card nonce generated with the &#x60;SqPaymentForm&#x60;) - Values for the &#x60;customer_card_id&#x60; and &#x60;customer_id&#x60; parameters (to charge a customer&#39;s card on file)  In order for an eCommerce payment to potentially qualify for [Square chargeback protection](https://squareup.com/help/article/5394), you _must_ provide values for the following parameters in your request:  - &#x60;buyer_email_address&#x60; - At least one of &#x60;billing_address&#x60; or &#x60;shipping_address&#x60;  When this response is returned, the amount of Square&#39;s processing fee might not yet be calculated. To obtain the processing fee, wait about ten seconds and call [RetrieveTransaction](#endpoint-transactions-retrievetransaction).
