AEM Edge Delivery Service, Form Submission to custom CRM like Sales Force
On an AEM Edge Delivery Service web site, we understand that the code is all frontend. As a current customer of AEMaaCS with a contract, and having 4 existing websites that serves on the platform. Adobe says using AEM Edge Delivery Service is free, so we wish to use this.
While customers are surfing our AEM Edge Delivery Service website, we wish to present a form to them. Once the form is submitted, we want post the data to a custom CRM like Sales Force. In order for us to connect to the CRM, we need some backend implementation which will connect to the CRM via Oauth2. What is the best way to archive this?
