How Do Timeout Settings Affect External REST Calls in a Visual App?

Timeout settings vary depending on how a service connection's backend is configured. Depending on the backend's connection type and authentication method, web apps can call external REST services directly or through the Visual Builder proxy.

If the REST service is:

• Called directly from the app, then you only need to worry about the browser timeout. Most browsers time out at around 4-5 minutes.
• Routed through the proxy, then in addition to the browser timeout, you should also be aware of the proxy timeout. The proxy times out if the REST API doesn't respond within 234 seconds.
