API02003: Token Invalid

What This Means​

The authentication token being used is not recognized by the server. This is different from an expired token — this token was never valid or has been revoked.

Common Causes​

  • Token revoked — An administrator revoked the session
  • Token corrupted — Data corruption during storage or transmission
  • Server reset — Server secret keys changed, invalidating all tokens
  • Wrong server — Token from a different WordPress installation

How to Fix​

1. Log In Again​

Clear your session and authenticate fresh:

  1. Log out completely
  2. Close and reopen the POS
  3. Log in with your credentials

2. Clear Application Data​

If logging out doesn't work:

  • Clear the POS app cache/data
  • On web: Clear browser cookies and local storage for the site
  • On desktop: Check app settings for a "Clear Data" option

3. Check Server Configuration​

If the issue affects all users:

  • Check if WordPress salts were changed
  • Verify JWT or authentication plugin settings
  • Review recent server changes

4. Verify You're on the Correct Server​

Ensure the POS is configured to connect to the right WordPress site, especially if you have multiple installations.
