Calling 3rd party shipping provider plugins

Monday, May 27, 2024

If you're trying to use a 3rd party shipping plugin by putting the plugin's System Name in the Option rule's Rate Expression but get an error e.g., "Error=No property or field 'ThirdParty' exists in type 'QueryContext'", then you need to prefix the name with "Shipping".

For example if your Rate Expression has

ThirdParty.UPS

Then change it to read

Shipping.ThirdParty.UPS

Hello.
I was experiencing an issue with the plugin "NopAdvance.Plugin.UPS", and I tried changing the System Name to "Shipping.NopAdvance.Plugin.UPS".

However, now I’m getting this new error:
"No shipping rate computation method found with the specified system name
Parameter name: Shipping.NopAdvance.Plugin.UPS"

Could someone help me resolve this issue?
I appreciate any assistance. Thanks in advance!
