Have you tried Mockoon to simulate slow API responses?

Adding a pause to your mock API is an easy way to check loading indicators, catch timeout issues, or explore performance edge-cases. Mockoon lets you set those pauses—per route and globally—in just a few clicks.

Need a mock server first?
Check out my previous Club post “Have you tried Mockoon to capture and mock real API responses?” for instructions.

Your task

  1. Open your existing Mockoon server
  2. Add a delay to one specific route.
  • Select the route.
  • In the Response panel, set Response delay (ms) to something noticeable, e.g. 2000.
  1. Add a global delay for all other routes.
  • Go to Environment → Settings.
  • Set Latency to a different value, e.g. 1000.

  1. Start the server and exercise your application or API client.
    Refresh a few times and watch how calls with the route-specific delay compare to everything else.

  2. Share your experience and thoughts in the thread:

  • Which delays did you set, and why?
  • **How did your application behave with those delays?
  • Where could latency simulation be useful in your own testing?
