Tip Adjust {#sis-cloud-sale-on-receipt-tip-adjust-intro}
========================================================

Use this information to process a tip adjust when the app is in Cloud mode. This follow-on transaction is required when processing an on-receipt tipping transaction. The tip adjust request must be sent within 24 hours to capture the transaction.  
After the original transaction is pre-authorized, the customer writes the tip or total amount on the printed receipt. A follow-on tip adjust request is then sent to capture the additional tip amount. This transaction is also referred to as an *overcapture* . For more information, see [Sale with On-Receipt Tipping](/docs/cybs/en-us/sis-pax/integration/all/rest/sis-pax/sis-pymnt-svcs-cloud-mode-intro/sis-cloud-sale-on-receipt-tip-intro.md "").  
Generate a bearer token before sending each request. For more information, see [Generating a Bearer Token for Authentication](/docs/cybs/en-us/sis-pax/integration/all/rest/sis-pax/sis-pymnt-svcs-cloud-mode-intro/sis-pymnt-svcs-cloud-mode-bearer-tkn-intro.md "").
