Hello Venkata, 

To resolve the destination connectivity issue you are encountering in the "Create SAP Build App to Trigger Workflow" step, follow these steps:

Verify Destination Configuration

1. Check Destination Configuration:

   • Ensure that your destination configuration is correct. Refer to the documentation provided and make the necessary configuration changes to the destination accordingly.
   • Verify that your destination configuration is correct. For more information about creating destinations, see Setting up HTTP Destinations 

2. Authentication Type:

   • Verify you've added the right authentication type. For more information about configuring authentication types, see Configuring Authentication 

3. OAuth Client Credentials Authentication:

   • If you're using OAuth Client Credentials Authentication, verify the settings 

Configure BTP Destination

1. Create a New Destination:
   • Open the subaccount used for developing with SAP Build Apps and navigate to "Destinations" in the "Connectivity" tab.
   • Click "New Destination" to start the setup process.
   • Configure the destination with the following exact inputs:
     • Name: Any desired name
     • Type: HTTP
     • Description: Any description
     • URL: https://spa-api-gateway-bpi-eu-prod.cfapps.eu10.hana.ondemand.com/public/workflow/rest/v1/workflow-i...
     • Proxy Type: Internet
     • Authentication: OAuth2ClientCredentials
     • Use mTLS for token retrieval: Off
     • Client ID: Paste the clientid noted previously
     • Client Secret: Paste the clientsecret noted previously
     • Token Service URL Type: Dedicated
     • Token Service URL: url/oauth/token, where url is the one noted earlier from the service key
     • Token Service User: Blank
     • Token Service Password: Blank
     • Additionally, enable the following Properties:
       • BuildApps.Enabled
       • HTML5.DynamicDestination
       • WebIDEEnabled
   • Your configuration should look similarly to the image below. Save your entries and check the connection with a button located below the fields. Proceed with the next steps if you see a green checkmark 

Additional Recommendations

• Region-Specific URL:
  • If your subaccount is located in the US region, modify the URL to have us10 instead of eu10
