Hello,
Has anyone had their 3dCart API simply stop working (e.g,, worked one day, not working the next day)?
While the error message is coming from the host system (Square), the response from Square is that it's 3dCart's issue. 3dCart has investigated (more than Square support was willing to do) and have again responded that the error message is coming from the host system (Square) so 3dCart can't process the credit card transaction.
