After a successful test, VendVice begins importing all your data from HaHa — machines, products, planograms, and order history. This can take up to 20 minutes depending on how many machines and orders you have. You can continue using VendVice while the import runs in the background.

Troubleshooting​

The test failed​

If the connection test shows Auth Failed or Failed:

  1. Click the edit icon (pencil) next to your credential
  2. Double-check that the username and password match exactly what you entered in HaHa
  3. Make sure you registered the user in HaHa with the Admin role
  4. Verify that all devices are selected for the user in HaHa
  5. Save your changes and try the test again

Still not working?​

  • Make sure the user you created in HaHa is active and not disabled
  • Try generating new credentials and repeating the process
  • Contact support at support@vendvice.com if the issue persists
