A <code>secure_smart_token</code> is a unique string of encrypted data values that authenticate PayNearMe orders within your app or website that is running the Embedded Client. The button used to invoke the PayNearMe JS Library requires a Smart Token to initialize the timed session within the iframe. Smart Tokens can be configured at the Site level to expire after a set amount of time or can remain the same for the duration of the order’s lifetime.</br></br>How you generate Smart Tokens will depend on how you configure orders. If consumers will be making payments at the time of order generation, use the /create_order call. If payments will be made after order generation, use the <code>/get_smart_token</code> call to regenerate an expired token for an existing order. A typical implementation uses the <code>/get_smart_token</code> call after creating orders via bulk upload. To regenerate the Smart Token for a specific order, use one of the following values:<ul><li><code>pnm_order_identifier</code></li><li><code>site_order_identifier</code></li><li><code>pnm_customer_identifier</code></li><li><code>site_customer_identifier</code></li><li><code>site_creator_identifier</code></li></ul><h2>Configuring the Smart Link</h2> The encrypted Smart Link URL (i.e., <code>secure_smart_link</code>) returned in the /create_order, /find_order, and /get_smart_token API responses contains all the consumer data passed in with the order and will display all payment types configured for the merchant site. To enforce specific flows or define specific redirect URLs, use the <code>/get_smart_token</code> call to customize the behavior of the Smart Link. For more information on configuring an encrypted Smart Link see Customizing the Secure Smart Link. Use the following parameters to put the consumer in a specific payment flow in the Embedded Client:<ul><li><code>flow_debit</code></li><li><code>flow_credit</code></li><li><code>flow_ach</code></li><li><code>flow_retailer</code></li><li><code>flow_apple_pay</code></li><li><code>flow_google_pay</code></li><li><code>flow_paypal</code></li><li><code>flow_venmo</code></li><li><code>flow_pin4</code></li><li><code>flow_push_debit</code></li><li><code>flow_push_ach</code></li><li><code>flow_cash_app</code></li><li><code>flow_push_paypal</code></li><li><code>flow_secure_all</code></li><li><code>flow_edit_schedule</code></li><li><code>flow_tokenize</code></li><li><code>flow_hide_saved_payment_methods</code></li></ul>To enforce a fixed, uneditable payment amount, include the <code>payment_amount</code> parameter along with the <code>payment_field_fixed=true</code> parameter. </br></br>To specify an expiration date for the Smart Link or return URLs for specific outcomes that can occur in the Embedded Client (e.g., errors, link expiration, etc.), use the following parameters:<ul><li><code>link_lifetime_seconds</code></li><li><code>short_order_url</code></li><li><code>flow_pay_url</code></li><li><code>flow_no_pay_url</code></li><li><code>flow_add_url</code></li><li><code>flow_no_add_url</code></li><li><code>flow_return_url</code></li><li><code>flow_expired_url</code></li><li><code>flow_error_url</code></li><li><code>flow_venmo_return_url</code></li><li><code>flow_show_all_ppas</code></li></ul><h2>Guaranteed ACH</h2> Gaming Operators on the PayNearMe for iGaming platform can use the <code>/get_smart_token</code> call to initiate Guaranteed ACH transactions using Trustly. To initiate a Guaranteed ACH transaction, include the following parameters along with the other required parameters for <code>/get_smart_token</code> calls:<ul><li><code>flow_trustly=true</code></li><li><code>ext_customer_enrollment_date</code></li><li><code>ext_customer_date_of_birth_pii</code></li><li><code>ext_customer_tax_id_pii</code></li><li><code>flow_bank_oauth_redirect_url</code></li></ul></br>For more information on PayNearMe's Guaranteed ACH solution, see the Guaranteed ACH guide.
