This error (An Error Occurred when trying to Create Shipment: The remote server returned an error: (403) Forbidden or (401) Unauthorized) from Evri typically occurs when there is an issue with the Evri business integration setup in Mintsoft.
To resolve this issue please review the steps below:
Check your Evri account type
The Evri business integration requires a Credit account, not a Pay As You Go account.
If you're unsure, please confirm your account type directly with Evri.
Verify the invoice flag setting
If you have confirmed you’re using a Credit account but still receive the error, it may be due to an issue with the invoice flag on your Evri account.
This will need to be reviewed and resolved by Evri.
Confirm the API key validity
Check if the API key entered in the Evri integration within Mintsoft has expired.
If expired, request a new API key from Evri and update it in the Mintsoft integration.
If all of this has been checked and you are still getting the error, please raise a new case online and reference the title of this article.
