Hello, If your request is to enable reference transactions for a sandbox account, they should be enabled already on all sandbox accounts. If this isn't the case for your sandbox account, please share the merchant id for the sandbox account and I can take a look. Details on how to retrieve the merchant id for a sandbox account can be found within the thread pinned to the top of this forum titled "how to report a sandbox issue". For production or live accounts, you would need to contact our customer service team to request reference transactions for your account. https://www.paypal.com/smarthelp/contact-us Thanks !
