The DHL plugin can also be used with a DHL system user. The system user has the advantage that the password only needs to be changed every 365 days.
For system user data, an error message appears in the configuration window for the plugin when using the Verify account button, stating that the access data is invalid and that it should be checked in the business customer portal. This message is to be ignored, as it is not possible to log in to the Business Client Portal with the system user data.
As soon as the correct login data of the system user as well as the customer number and participation numbers are stored in the configuration window, the DHL plugin can be used as usual.
