PublisherDesk

This is a WordPress plugin for clients of The Publisher Desk, intended to automatically propagate changes made to The Publisher Desk’s ads.txt file to client websites, while letting them add/retain custom lines as desired.
<h3>Functionality</h3>
This plugin provides management of the ads.txt file (Authorized Digital Sellers), an initiative from IAB Technology Laboratory, geared towards client of The Publisher Desk. Because the administration of a file outside the wordpress directory can pose challenges depending on the WP/Server configuration, the plugin decides on installation whether to use an actual ads.txt file in the root of the domain, or a quasi-ads.txt file built through a WP option and responding to a server request for “/ads.txt” by providing the contents of that option (containing both custom lines and those associated with TPD’s centralalized list).
Troubleshooting an installation: 
If you already have an ads.txt file present on your site, the plugin will rename it to ads-txt-original.txt on installation, and re-rename that file back on de-installation. If your site’s wordpress instance doesn’t have access to files outside of its installation directory and you already have an ads.txt file, the plugin won’t be able to dislodge the existing file and allow the management of the one it creates. You can check whether this has happened if you check your site’s ads.txt file directly (site.com/ads.txt) and there’s no line reading: 
 “### END TPD ADS TXT ###” 
a line that is used by the plugin to demarcate custom entries and The Publisher Desk’s. If this is the case, please deactivate the plugin, rename or remove your existing file, re-activate, and check the file again (you might have to refresh several times depending on caching). If you still don’t see that line and the file looks the same as before the update, please reach out to TPD for assistance.
Final Note: it’s good practice to have a backup of your custom ads.txt lines. We have functionality for retaining your custom lines on plugin updates/re-installs, but it’s good to make sure since it can be a big pain to recollect entries if you lose them.

ABOUT ADS.TXT
The IAB Tech Lab recently introduced the Ads.txt initiative (official website) to increase transparency in the programmatic advertising ecosystem. The “Ads” in Ads.txt stands for Authorized Digital Sellers, and it is a relative simple method for publishers to declare who is authorized to sell their digital inventory. In short, the Ads.txt file contains the publisher’s out loud references for his authorized sellers.
The process is pretty straightforward. The publisher puts a text file in his web server on the root level of the domain (publishersdomain.com/ads.txt), it must be called ads.txt, and it must have its Read permissions set to “World”. The file must obviously follow the IAB format (see below).
This file should list all of the companies that are authorized to sell the publishers’ inventory. Similarly, programmatic platforms will integrate ads.txt files to confirm which publishers’ inventory they are authorized to sell. This will allows buyers to check the validity of the inventory they purchase.
ABOUT ADS.TXT PUBLISHER
Ads.tx Publisher was created by Brightcom, a leading media house and a strong supporter of the Ads.txt Initiative to allow publishers to easily edit, validate and upload their ads.txt files within WordPress without any need for engineering resources and with the same ease as any other media asset.
TECHNICAL NOTES
<ul>
<li>Requires PHP 5.3+.</li>
<li>Requires WordPress 4.9+. Older versions of WordPress will not display any syntax highlighting and may break JavaScript and/or be unable to localize the plugin.</li>
<li>Rewrites need to be enabled. Without rewrites, WordPress cannot know to supply /ads.txt when requested.</li>
<li>Your site URL must not contain a path (e.g. https://example.com/site/ or path-based multisite installs). While the plugin will appear to function in the admin, it will not display the contents at https://example.com/site/ads.txt. This is because the plugin follows the IAB spec, which requires that the ads.txt file be located at the root of a domain or subdomain.</li>
