How can I call an API in Power BI when connected through a VPN?

I need to integrate an external API with Power BI while being connected through a VPN. What challenges might arise when calling an API under such network constraints, and what are the best practices or workarounds to ensure seamless API integration, authentication, and data refresh within Power BI?

Challenges When Calling an API via VPN

1. Network Restrictions & Firewalls

   • Some VPNs restrict API calls or external web requests.
   • Firewalls may block Power BI from reaching the API endpoint.

2. Authentication Issues

   • API tokens may expire if VPN connections disrupt session management.
   • Some APIs require IP whitelisting, which may change with a VPN.

3. Performance & Latency

   • VPN routing may slow down API response times.
   • Large API responses can cause Power BI timeouts or refresh failures.
