OIC - Can you explain how you use REST and SOAP connections in OIC?

Answer:

In Oracle Integration Cloud (OIC), REST and SOAP connections are set up to enable communication with external applications or services that expose their APIs in these formats.

🔹 REST Connections:

• I create REST connections using the REST Adapter in OIC.
• The connection is configured by specifying the base URL, authentication (like OAuth 2.0, Basic Auth), and optional headers.
• I typically use REST connections to integrate with modern web services, like external APIs or Oracle SaaS REST endpoints (e.g., ERP/HCM Cloud REST APIs).

🔹 SOAP Connections:

• I create SOAP connections using the SOAP Adapter.
• This involves uploading the WSDL file or providing the WSDL URL.
• The adapter uses the WSDL to define available operations and data structures.
• I use SOAP connections for integrations with legacy systems or Oracle SaaS SOAP web services (e.g., certain HCM/ERP services that are still SOAP-based).

✅ Practical Use in OIC Integrations:

• Once the connections are created, they are used in the integration flow.
• I drag and drop the REST or SOAP connections onto the integration canvas as invoke actions to send or receive data.
• In the mapper, I map the incoming or outgoing payloads to match the API’s structure.
