When I try to integrate the Parcelforce integration, I get the following error message:

EnterDetailsStage: Failed to validate user details with ParcelForce


The error message indicates that the credentials used, specifically username and/or password, are incorrect.

To fix this, check that the following points are taken into consideration:

1. User name

The user name should be the same as used for expressLink and be in the following format: EL_WDMxxx. 

Any other variation/format will not work. 

2. Password

The password should be the same as used for the expressLink password. 

Double-check that the used credentials are the same and try to integrate Parcelforce once more.

If the issue is still present, feel free to contact Linnworks Technical Support for further help!
