Is there a webservice or REST API to Update Customer Transacations & Credit Memo in Fusion AR?

Hi Guys,

i need to know if there is a webservice or REST API to Update Customer Transacations & Credit Memo in Fusion AR? the scenario is we are try to define Approvals on Customer transactions and Credit memo using PCS. As work around, once approved in Process Cloud service we mark the transaction as complete using below REST API (these only update limited information). But we need to update the status of Approval by updating any DFF or Standard field using webservice or API. It will be helpful if someone can share the solution. Thanks in advance.
