Testing and Debugging

The Nexx360 Prebid adapter supports several parameters for testing and debugging, passed through the OpenRTB ext object or detected from the page URL.

Debug mode

Debug mode enables detailed information in the bid response, including SSP transaction details and eligibility logs.

Debug mode is activated when any of the following is true:

• test: 1 is set in the bid request

• nexx360_debug=1 is present in the page URL (site.page)

• nexx360_debug: 1 is set in the request ext

Enabling via page URL

Simply add the query parameter to your page URL:

https://example.com/page?nexx360_debug=1

Enabling via request ext

pbjs.setConfig({
    nexx360: {
        // ... your config
    }
});

// In the bid request ext:
{
    "ext": {
        "nexx360_debug": 1
    }
}

Force test creative

You can force a Nexx360 test creative to validate your integration without relying on live SSP demand. This is useful for verifying that ad slots render correctly.

Via page URL

Add one of these parameters to your page URL:

• nexx360_test=1

• nexx360_force_creative=1

https://example.com/page?nexx360_force_creative=1

Via request ext

{
    "ext": {
        "nexx360_force_creative": 1
    }
}

Force test creative at a specific price

To test pricing flows end-to-end, you can force a test creative at a specific CPM. This automatically enables the test creative (no need to also pass nexx360_force_creative).

Via request ext

{
    "ext": {
        "nexx360_force_creative_price": 10
    }
}

Via URL query parameter

You can also force the creative price from the Booster / OpenRTB endpoint URL:

POST /booster?nexx360_force_creative_price=10
POST /open-rtb?nexx360_force_creative_price=10
POST /prebid-server?nexx360_force_creative_price=10

If both the URL query parameter and the body ext are provided, the body value wins.

The test creative will bid at CPM 10 in the auction currency.

Force bids

By default, Nexx360 applies bid reduction rules to optimize traffic. You can bypass this for testing purposes.

Via request ext

{
    "ext": {
        "nexx360_force_bids": 1
    }
}
