I am new for Magento and want to create REST API of instant purchase functionality for mobile application using Magento version 2.2.6. I have configured instant purchase option for site and it's working fine.
To create API for instant purchase, I have googled but unfortunately did not find api url for instant purchase. I have already worked for magento API like add to card, list products...etc but unable to create for instant purchase. So could someone suggest me if possible, how to do this?
Thanks
