I'd be interested to know if anyone has experience of setting up a Shipping App to work with UPS and An Post in Ireland. Currently, we only ship within the Rep. of Ireland from our depot to domestic customers. In time we will use our courier to do international shipping.
I am also looking for the same.
@Keoghscrisps_ for the app you mentioned above, does that provide you with discounted UPS rates (vs. their standard rates on their website)? What kind of rates are you seeing for shipment to the US, if I may ask.
I feel your pain, I have tried every app. What was the challenge with connecting to the UPS account, was it the missing postal or zip code? I'd love to know your challenges as I have escalated this to UPS. Feel free to drop me a direct line.
I was able to successfully connect to ShippyPro and ShipTheory.
Hope this helps
