Expose Integration Flow Endpoint as API and Test the Flow

[Ochowicz]

Tutorial issue: Step 2 "Try Out > Execute" returns 404 (router page) instead of expected 401 in Integration Suite Trial (APIM)

Title/Topic: Expose Integration Flow Endpoint as API and Test the Flow

Issue:
In Step 2 “Define the API”, point 12 says that Try Out → Execute should return HTTP 401 (Unauthorized) because no authentication is configured yet. In my Integration Suite Trial (ap21) I consistently get HTTP 404 with an HTML router page (“Sorry, the page you are looking for is currently unavailable. Please try again later.”). Calls counter stays 0, so the request seems not to reach the API proxy/gateway.

Environment:

• SAP Integration Suite Trial
• Region: ap21
• API Management runtime activated via Integration Suite Settings → Runtimes → API Management

Cloud Integration (CPI) backend works:

• iFlow is Deployed and Started
• Direct iFlow endpoint is reachable and returns 401 (Unauthorized), so backend is OK:

API Proxy configuration (as per tutorial):

• Target EndPoint URL (without /details):
  https://krzyszto-ochowicz-6f9nlghe.it-cpitrial03-rt.cfapps.ap21.hana.ondemand.com/http/products
• API Base Path: /products
• Resource: POST /details
• API state: Active
• Proxy deployed successfully
• API Proxy URL shown in Overview (after provisioning):
  https://nysltvv8gdmhkckkk7lj-trial.integrationsuitetrial-apim.ap21.hana.ondemand.com:443/krzyszto-ochowicz-6f9nlghe/products

Expected:

• Try Out → Execute returns 401 (Unauthorized) before authentication is configured (tutorial Step 2, point 12).

Actual:

• Try Out → Execute returns 404 (Not Found) + HTML router page (“currently unavailable”).
• Direct calls to the API Proxy URL also return 404.

Troubleshooting performed:

• Re-created the API proxy multiple times
• Undeploy/Deploy proxy
• Activated API Management runtime in Integration Suite (Settings → Runtimes → API Management)
• Removed standalone API Management instance/subscription from BTP subaccount (kept only Integration Suite)

PowerShell test results (curl.exe):
POST requests return 404 for all tested paths:

Request:
Can you confirm whether the tutorial is still valid for current Integration Suite trial tenants and if an additional onboarding / virtual host / gateway routing configuration step is missing? It appears the API proxy URL is not routable (router 404) even though the proxy is deployed and API Management runtime was activated.
