Setting up your ads.txt file

Introduction to ads.txt #

All of the exchanges we run through NitroPay require a valid ads.txt file on your site. If you don’t set this up properly, you’ll be missing most if not all of the high-paying revenue opportunities that are available to you.

Per the one-hop rule in the IAB specification, it is highly recommended that you set up a 301 redirect from yourdomain.com/ads.txt to the hosted ads.txt file maintained by NitroPay. Setting up a redirect ensures that you are kept up to date to any changes and not at risk of lost revenue.

We have documentation for settings up redirects on Apache, Nginx, Cloudflare, and others.

The URL to your custom ads.txt is below, where #### is the ID of your site which can be found in the panel.

https://api.nitropay.com/v1/ads-####.txt

Alternatively you can copy the contents of our hosted ads.txt and host it locally on your site’s ads.txt file, but this discouraged as we add new partners regularly and it will be your responsibility to update the file.

Custom entries may be added by visiting the Sites configuration on the NitroPay Panel.
