What does 'Custom Proxy' means?

The 'Custom Proxy' feature indicates that a subscription plan does not include Proxy in its base price, thus a 3rd Party Proxy provider has to be used.

This configuration is exclusively available to the Scale plan users, as due to it having unlimited page credits available to it, the Proxy has to be added separately.

Once a Scale plan has been acquired, your account will have an additional 'Proxy Manager' page available to it

Here you will be able to find the instructions on how to integrate the Proxy as well as select the Proxy provider you would like to use alongside specifying the country of origin for said Proxy.
