How to fix Delhivery "Authentication failed, please check warehouse details" error?

This error appears when the API token saved in ILS is rejected by Delhivery.

Why this happens: Your API key is wrong, expired, or belongs to a different Delhivery account than the warehouse you're trying to ship from.

How to fix:

  1. Log in to Delhivery One and go to Settings → API to copy your active API token.

  2. Open ILS → Logistics Configuration → Delhivery.
  3. Paste the token into the API Key field (test or live, matching your Test Mode setting).
