OData uses HTTP, AtomPub, and JSON as its core functionalities. OData is an open protocol that allows the creation and consumption of queryable and interoperable RESTful APIs in a simple and standard way. OData builds on HTTP as the application protocol for transferring data between clients and servers. OData uses AtomPub as one of the formats for representing data feeds and entries in XML. OData also uses JSON as another format for representing data feeds and entries in a lightweight and human-readable way. References: Introducing OData - SAP Learning, OData Overview | OData - The Best Way to REST

To send messages over a SOAP adapter to an integration flow, you must use the POST method. The POST method is used to create or update a resource on the server using the SOAP message body as the input. The SOAP adapter supports both SOAP 1.1 and SOAP 1.2 protocols and can handle both one-way and request-reply message exchange patterns. The SOAP adapter can be configured as a sender or a receiver channel in an integration flow. References: SOAP (SOAP 1.x) Adapter | SAP Help Portal, SOAP Sender Adapter: Example Integration Flow | SAP Help Portal
