Update order

Updates an order with a CREATED or APPROVED status. You cannot update an order with the COMPLETED status.<br/><br/>To make an update, you must provide a reference_id. If you omit this value with an order that contains only one purchase unit, PayPal sets the value to default which enables you to use the path: <code>"/purchase_units/@reference_id=='default'/{attribute-or-object}"</code>. Merchants and partners can add Level 2 and 3 data to payments to reduce risk and payment processing costs. For more information about processing payments, see <a href="https://developer.paypal.com/docs/checkout/advanced/processing/">checkout</a> or <a href="https://developer.paypal.com/docs/multiparty/checkout/advanced/processing/">multiparty checkout</a>.<blockquote><strong>Note:</strong> For error handling and troubleshooting, see <a href="https://developer.paypal.com/api/rest/reference/orders/v2/errors/#patch-order">Orders v2 errors</a>.</blockquote>Patchable attributes or objects:<br/><br/><table><thead><th>Attribute</th><th>Op</th><th>Notes</th></thead><tbody><tr><td><code>intent</code></td><td>replace</td><td></td></tr><tr><td><code>payer</code></td><td>replace, add</td><td>Using replace op for <code>payer</code> will replace the whole <code>payer</code> object with the value sent in request.</td></tr><tr><td><code>purchase_units</code></td><td>replace, add</td><td></td></tr><tr><td><code>purchase_units[].custom_id</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>purchase_units[].description</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>purchase_units[].payee.email</code></td><td>replace</td><td></td></tr><tr><td><code>purchase_units[].shipping.name</code></td><td>replace, add</td><td></td></tr><tr><td><code>purchase_units[].shipping.email_address</code></td><td>replace, add</td><td></td></tr><tr><td><code>purchase_units[].shipping.phone_number</code></td><td>replace, add</td><td></td></tr><tr><td><code>purchase_units[].shipping.options</code></td><td>replace, add</td><td></td></tr><tr><td><code>purchase_units[].shipping.address</code></td><td>replace, add</td><td></td></tr><tr><td><code>purchase_units[].shipping.type</code></td><td>replace, add</td><td></td></tr><tr><td><code>purchase_units[].soft_descriptor</code></td><td>replace, remove</td><td></td></tr><tr><td><code>purchase_units[].amount</code></td><td>replace</td><td></td></tr><tr><td><code>purchase_units[].items</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>purchase_units[].invoice_id</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>purchase_units[].payment_instruction</code></td><td>replace</td><td></td></tr><tr><td><code>purchase_units[].payment_instruction.disbursement_mode</code></td><td>replace</td><td>By default, <code>disbursement_mode</code> is <code>INSTANT</code>.</td></tr><tr><td><code>purchase_units[].payment_instruction.payee_receivable_fx_rate_id</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>purchase_units[].payment_instruction.platform_fees</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>purchase_units[].supplementary_data.airline</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>purchase_units[].supplementary_data.card</code></td><td>replace, add, remove</td><td></td></tr><tr><td><code>application_context.client_configuration</code></td><td>replace, add</td><td></td></tr></tbody></table>
