Please visit this new guide on Getting started with Shiptheory and FedEx
FedEx requires any of their users to be signed off before their production details will work, this is a fairly easy process as you'll just need to create a label using your test details and send it to email@example.com, asking them to approve your production details, you should then get a response confirming this and you'll be able to use your production details in Shiptheory.
If you'd like to create a test shipment in Shiptheory rather than creating an entirely new order in your web store, you can use our manual shipments form, which you can access directly from this link.
If you have any issues or queries regarding your details feel free to contact support.
