+Proposed Solution: 
+
+1.	Synchronous Outbound Integration:
+  >	 Utilize the REST integration step within the Flow Designer to send request details to the third-party endpoint.
+  >  The third-party system is expected to send an acknowledgment upon receiving the request, confirming that it is being processed.
+2.	Status Tracking:
+    >	Introduce a new field or leverage an existing field in the sc_req_item table (or another relevant table) to track fulfilment status, with choice values such as "Success" or "Failure."
+3.	Inbound Import Set API:
+    >	Create an Inbound Import Set API that allows the third-party system to send updates back to ServiceNow. The fields in the import set table should include:
+          Request Number: A unique identifier for the request.
+	        Fulfilment Status: The status of the fulfilment (e.g., Success or Failure).
+	        Work Notes: Additional comments or information regarding the fulfilment process.
+4.	Transform Map:
+    >	Establish a Transform Map where:
+	      a. Source Table: The Import Set Table that receives the status updates.
+        b. Target Table: The sc_req_item table (or another relevant table based on the use case).
+	      c. Define field mappings to ensure accurate data transfer and use coalescing on the Request Number to allow updates only.
+        d. Map the fulfilment status field from import set to new custom field to store the fulfilment status in sc_req_item table.
+5.	Flow Changes:
+	 >  Update the request stage based on the integration fulfilment status value
+6.	API Sharing:
+    >  Provide the Inbound Import Set API to the third-party system, enabling it to send fulfilment status updates once the fulfilment process is complete.
