Oracle EBS Tech Integration Jobs

Hi, Good day. I am looking for someone who can guide me on how to work with Oracle Integrated SOA gateway. My main objective is to integrate Mendix (low code application development platform) with Oracle EBS 12.2.4. I need to read/write to Oracle EBS DB. How can I achieve this? Questions: What are the available scenarios? How can we publish Oracle standard API’s as a REST or SOAP API’s? What is the difference b/w REST or SOAP API’s? How can we publish custom PL/SQL procedure/functions queries? Note: we have applied Oracle REST API's patches.
