Fix the WooCommerce authorisation - currently doesn't work!
The woocommerce integration doesn't work - I get an error message (missing parameter app_name) when trying to authorise Click & Go with Woocommerce.

Hi Bex,
Unfortunately due to WooCommerce being a self hosted integration we can sometimes run into errors, we are currently not aware of any issues regarding our WooCommerce integration. You may wish to contact our helpline for further assistance, the contact information can be found here: https://help.parcel.royalmail.com/hc/en-gb/articles/115003806094-Contact-Support.
Due to the lack of support I will be closing this as our integration is functioning as intended.
