AffiliateWP includes a full read-only  RESTful API  that allows developers and external applications to interact with data in the AffiliateWP databases. This REST API Extended add-on adds Create, Update, and Delete operations into the mix, giving developers and external applications  complete  control over data in the AffiliateWP databases. With the REST API Extended add-on, the following actions are available to the REST API for affiliates, creatives, referrals, visits, and payouts: Create affiliate/creative/referral/visit/payout Update affiliate/creative/referral/visit/payout Delete affiliate/creative/referral/visit/payout The possibilities enabled with this extended API are nearly endless. A few examples of possible applications include: Visit and referral tracking from external websites, including non-WordPress sites Referral tracking in custom and non-WordPress eCommerce systems Synchronization of affiliate accounts across multiple databases and servers Automatically updating affiliate accounts when changes are made from external applications Creating referral records for affiliates each time an order is processed in an external payment processor Custom affiliate areas hosted outside of WordPress See our  documentation  for examples of the REST API Extended in action and for assistance in building your own applications!
