Operation not implemented, what can I do?

I have received a operationImplemented: false in my response. What does it mean?

It's one of the Common Elements (Boolean) returned in our API response. It informs you whether the method requested has been implemented by the Seller:

<operationImplemented>false</operationImplemented>

or

<operationImplemented>true</operationImplemented>

If you believe this method should be implemented by the Seller, please contact them directly so that they can check it on their side.
