How to fix Bluedart "Authentication failed" error?

This error appears when Bluedart's API rejects the credentials sent from ILS during shipment booking.

Why this happens: API credentials in ILS don't match what Bluedart expects for your account. Usually a copy-paste error, a rotated key, or a switch between test/live keys.

How to fix:

     
  1. Open ILS → Logistics Configuration → Bluedart.  
    2.  
  2. Re-verify the Login ID and License Key character by character against Bluedart's shared credentials.
    3.  
  3. Make sure you're using the correct set for your Test Mode setting (test keys for Test Mode ON, live keys for Test Mode OFF).
    4.  
  4. Click Save. If it still fails, ask Bluedart to reset or re-share the credentials.
