GET ../api.ordoro.com/product?dropship=true
GET ../api.ordoro.com/product?dropship=TRUE
GET ../api.ordoro.com/product?dropship=1
GET ../api.ordoro.com/produc/dropship/1
The /product?dropship=true endpoint should work correctly.
If you could post the x-api-request-id as well as the x-apiverson-request-id in the response headers and send us the error you are receiving then we can help you diagnose the issue.
I just ran into this the other day as well. I think you just need a trailing slash for the product endpoint.
So instead of: GET ../api.ordoro.com/product?dropship=true
You should use: GET ../api.ordoro.com/product/?dropship=true
